Title: Turbo trainer
Post by: salar55 on 17 March, 2020, 10:18:42 am
Have an old Elite realpower trainer its about 12 years old, whats a good one today. Its been faultless apart from starting up, sometimes takes 3 or 4 attempts to connect to the computer. Anyone using the Elite Drivo ones? Or whats another good one, dont want computer generated images on the screen, old one has video climbs.

We have Drivos and the cave looks like this:

You basically have a choice of wheel on or wheel off. If you have the cash, go for wheel off as they are quieter and don't wear down your tyres (assuming your bike will fit - check for through axle compatibility etc depending on what you want to put on there).

After that, there are a few brands that are reputable - Elite are one of those. The best place to check out reviews is probably https://www.dcrainmaker.com/2019/10/the-smart-trainer-recommendations-guide-winter-2019-2020.html - DC Rainmaker knows his stuff. How you control your smart trainer is up to you - there are quite a few platforms, and a basic one will probably come free with your trainer.

I bought a StacZero Halcyon last year - wheel on, uses magnetic induction on the wheel, with some weights on the spokes.  I connect it to the Tacx software via ANT+.  Instead of swapping wheel weights on and off, I have a tyreless wheel that I swap in an out.

It's bloody quiet, just the noise of the chain and your breathing tortured gasping for air

Stac got bought by 4iiii's last year. There is a 4iiii's version of that trainer out, which has some cool developments, but also some disappointing power limitations. I was reading the DC Rainmaker review today as it popped up and they are such a neat idea...

I don't think that will apply to me with my paltry 3.2 W/kg ftp

I've been on the elite ones and they are lovely. However, I got a tacx neo - done 17,000km on it. Whatever you get, if you are doing lots of miles on it, it's probably not worth skimping. Mine can simulate 25% climbs and has roadfeel surface simultion. Sounds like you don't need any of that. Still, they do feel different - the Neo is deliberately flexy, which is good for carbon, but like rocker plates, requires some adjustment if you sprint.

The Elite drivo 2 has good reviews, same gradient max as old one. The videos are important as i get bored easily, not interested in CGI. Less space taken up with no rear wheel, that's a plus and just found out its mac compatible unlike the old turbo. Wonder if the demand for turbos have shot up as i don't want for ages if not in stock. If i get back from Spain will look for a good price.

Depends how heavy you are. DC Rainmaker seems to think that for someone with an FTP much above 200W, VO2 and anaerobic intervals might be an issue: https://www.dcrainmaker.com/2019/12/4iiii-fliiiight-smart-trainer-in-depth-review.html
Title: Re: Turbo trainer
Post by: ElyDave on 18 March, 2020, 01:50:39 pm
70kg, so FTP around 220-230W, intervals I'm normally peaking around 250-300W.  The odd thing is at start up as the wheel is moving slow, the magnets move closer adn then back off, so you can end up doing a peak wattage of 4-500 just to get going and then sit at a steady 150-200 for the rest of an hour.

I bought it partly on the basis of ability to use with the FWD 'bent based on another forum, but also reading DCRainmaker's earlier review when they were still StacZero

I have a Neo (though it's about to get loaned out) - the flexiness bothers me, but that might be because I'm used to really solid static bikes.

I miss my old Tacx Speedbreaker, which was a PROPER turbo trainer...just a centrifugal fan and a flywheel.  It was noisy but it did a pretty good job of simulating real-world resistance.  The magnetic thing I have now is rough by comparison, if quieter.

I have a KICKR just finished it’s 3rd winter and it’s been solid , I do though find it very stiff and have to use more cadence than on the road 100 or more or it tends to hurt my knees/hips so I would try a Neo if I was getting another .

Bought a Drivo 2, good price saved £500. Set up the turbo, wheel circumference etc, 1st run i am a superstar ( no way) . Downloaded a climb (Sierra Nevada ski road up to the petrol station at 16km stopped there as its 27km total. ) and checked against the same section of the climb on Strava (real world) a lot faster on the turbo🤔. Reset the turbo to get the times similar for climb. Zwift has a default setting of 50%, so if its up to you to set resistance whats the point of signing up for races.

Oh it’s possible as the GPS track generated looks no different to if you’d done it outdoors. It’s just the way it is submitted to Strava that means it appears under a virtual ride. I’m sure there’s a few out there populating KOM as some of times seem barely credible for uphill segments.

Well, that's not how the original Digital EPO used to work (see other thread for more info), but anyone can mess around with the files that GPSes spit out.

Anyway, back to Turbos. I got given a very basic trainer for my downstairs neighbour (he runs a removals company and gets given tonnes of junk to dispose of). I can't set it up easily in a 1st floor flat (I did get a trainer mat) and especially not now we're all holed up here - there's enough cabin fever already.
Title: Re: Turbo trainer
Post by: drossall on 26 March, 2020, 02:50:08 pm
I've got a basic one that a clubmate gave me some years back. It was really for a Scout activity - we had them "racing" on static bikes. I tried it the other day, and it's so noisy that I don't dare use it even in the back garden! Also it's a fan-resistance model so it doesn't really give much resistance. I think my ideas of trying Zwift may have to go on hold. Luckily my wife has a very old, traditional, but fairly decent exercise bike, made before anyone had ever heard of connecting the things to anything. It does a few programmes, but the controller runs on a couple of D cells if I remember correctly.

Finally managed to track down a Kickr.  Rare as hen's teeth at the moment so very pleased.

I've never used a trainer of any kind so this is going to be a novel experience.  I'll be using it in the back yard while the weather stays dry so no 3rd party apps or screens - I'll rely on HR and wattage info to judge efforts.

Any suggestions for getting going?
Title: Re: Turbo trainer
Post by: DuncanM on 27 March, 2020, 01:42:57 pm
What do you want to do on it?  Just ride along? Some form of structure for each ride? A structured plan?

Assuming you have a modern smartphone, you can use that to control the turbo. Zwift probably wouldn't be much fun, but the OEM app would probably work, and stuff like Trainer Road is happy on a phone screen too. An elastic band over the Garmin mount will hold it in place (maybe a zip tie around the stem for extra support). If you want to give TR a go (either choosing a workout as as you want, or building a plan), PM your email and I'll send you a months free trial.

Thanks Duncan! PM sent.

I'll probably be doing intervals, trying to replicate what I've been doing in the gym, so 1-hour above/below FTP.

Never thought about using phone as a screen.  I've also got a tablet so could maybe rig that up on a stand of some kind.

If you have a music stand then a tablet would go on one of them nicely.  You should get an email with your referral link from TR today.

Is there anywhere that's good for feeding in some requirements and seeing what's available? Product descriptions aren't always clear. For example, I don't think I can justify the cost of wheel-off, I'd quite like to let Zwift or similar control the trainer, and I'd really like to use my old 5/6 speed road bike = narrow drop-outs.

Not that anything's available at present anyway, of course...

You want a smart trainer that supports ANT+ FE-C, Bluetooth Smart open. If it supports those it’ll work with any smart trainer app including Zwift.

If it says "smart" and "Zwift compatible" it's a start. Beware there are models that say both these things *don't* allow electronic control of resistance - it just means they have a speed sensor or something. You really need to read the reviews/specs very carefully to know which is which. If it's got a manual control lever on a cable that's a bad sign.

For a wheel-on you'd just insert a spacer between the supplied QR and the frame, or maybe not even that. If it's not QR you need special nuts to interface with the trainer.

That's my impression - and the reviews, not the manufacturers' specs, because they sometimes obfuscate it on purpose. Thanks for the lever tip.

It's true, but all this has sparked my interest. As above, I have a plan B for now, so I'm prepared to take a slightly longer view and wait for something suitable to be available. We don't know how long this will last, and models will come back into stock eventually. There may even be offers if the market has now been saturated. Not to mention a flood of little-used ones on eBay!

Hi, I do audax and now things have changed....I need to support the NHS of course, and feel like I am liking in a very cosy cage!
Anyhow I started doing Training Peaks sessions with a Yahoo Elemnt Bolt on a WattBike at a local gym two months ago as the weather was so bad, however the gym has closed now.
So what sort of turbo trainer do I need at home to use the Elemnt Bolt to do Training Peaks sessions?
I have access to an Elite Turbo Muin Smart B+ turbo trainer which has been in a box for 2 years and never used, but will this work with the Elemnt Bolt?
If not what do I need?

At her request, I tried to set up my daughters 24" wheel bike on my old Tacx Booster. The latest one can accommodate 24" wheels, but mine must be a bit older - it only goes down to 26". :( She's not so enthusiastic about riding the rollers (fair enough, they are a bit scary) - any suggestion of how I can provide some resistance with the wheel hanging in space?
Title: Re: Turbo trainer
Post by: Phil W on 30 March, 2020, 11:45:05 am
Might sound daft but would a 26” wheel fit in her frame ? Not ideal on road but might work on turbo if frame has clearances. Then raise front wheel a bit with a stable block of wood. Remember the rear brake wouldn’t be used and wouldn’t need to be fitted for turbo use.

Otherwise playing cards taped to every spoke on her rear wheel?

Molish a stand-off to support the resistance unit closer to the wheel.  Here's a not very good photo:

(http://www.ductilebiscuit.net/gallery_albums/sprint/IMG_3258.sized.jpg)

Ingredients:  A couple of bits of MDF (sheet metal would be better), 1 long bolt to go all the way through the resistance unit, a couple of woodscrews each side (nuts and bolts if using metal).

That I've never got round to making a decent version out of the 3mm aluminium I've got kicking about is a testament to our infrequent turbo use.

I have some 1.6mm zintec sheet kicking around, but the way the brake unit attaches isn't as simple as in your example. I'll have to see how the pivot point is attached. It looks like this:

Mine goes to within a few degrees of horizontal, but that makes it harder to read the score :D

1.6mm zintec sheet I had lying around, plus a couple of nuts and bolts to move the pivot point. Works nicely with her Islabike Luath 24.
Now let's see if she will actually ride the thing longer than 10 seconds!

I am wondering if I will have to do the same thing to my smart trainer (Bushido smart) so she can go on Zwift and make it interesting for her!

Woke with a cunning plan for knocking up a tablet stand from stuff to hand.

Made a wooden frame to sit around a worklight & stand with a resting ledge on the bottom.  Took about 30 minutes.  Finished off with a bit of black gaffer tape (quicker than painting!)

I've been thinking for a while that I ought to look into getting a turbo trainer. Had a chance glance at Ebay this morning and there was one for sale in Wickford, only 10 mile from here. Put in a bid and won it. Within 2 hours of the bid going in, the guy had delivered it.

The only drawback is that the QR skewer on my Thorn is too robust to fit the machine so I have ordered a TACX one from the LBS. That should arrive soon.

It's a Cycleops Magneto or some such. Will have a play when the QR skewer arrives.

Finally succumbed to jumping back on the turbo too. We have total lockdown here at home so no riding at all off property.
I picked one up about 18 months ago to do hard sustained efforts for race training, but found a knee injury flared up and abandoned the idea.
Since then we put an old rust bucket on the turbo that just about fits myself and Ms Morbihan. There is an old rusty triple set up with an 8 sp cassette. Some gear selections actually work :-)
The couple of sessions I have had didn't seem to aggravate my knee which is a pleasant surprise. Whether it is the smaller frame, a flat pedal and sneaker set up, or shorter cranks the my racing bike I don't know. Im just ecstatic to be able to turn some pedals TBH.

First session on the Kickr today doing a Trainerroad ramp test.  FTP 223 which sounds about right and leaves plenty of scope for improvement!

Everything working really well - Kickr synced to Tickr HRM, Bolt, TR on tablet (on bodged up stand which does its job).  Outside on the patio and the floor fan was on full blast.

Ah - interesting.  I'm hoping for a bit of improvement so have set up a 1-month plan (I know - very short, but that's the length of the trial period - thanks DuncanM!).  I'll see how that goes and then probably start paying.

I've got to say the Kickr feels good and works really well - syncs up with everything faultlessly.  The workout even gets logged on RideWithGPS (what I use for road stuff) automatically.  Really happy  :thumbsup:

Just finished my first TR session proper.  Reinstein 90min.  Easier than I was expecting - massive recovery intervals so got a bit bored at times. The tri-bars are really useful for those  :)  I suspect the ramp test yesterday may have given too low an FTP - I didn't really prepare for it so may not have given everything.  I'll do another in a week or so.

Final tweaking/adjustment/positioning of equipment.  I've gone as far as marking positions of everything on the mat so I can replicate the setup precisely  ::-) ;D

I have, in the past - though we're mostly a Zwift household these days.

You can do TR workouts on Zwift; just let TR control your trainer, and "free ride" on Zwift. Another decent integration is Zwift/TrainingPeaks; if you're on a programme on TP, your workout will appear as a custom workout in Zwift, and you can ride it on there as a Zwift workout.

Thanks Chris.  That's really useful.

I'm thinking that maybe TR in the warmer months when I'm hopefully able to set up outside, then possibly move over to Zwift in the winter when I'm in the spare bedroom facing a wall. I could set up a TV for some extra motivation. 

Another limiting factor is the cheapo tablet I'm using outside at the moment -  it's fine for TR but can't handle the graphics of Zwift.

I use a PC, but a perfectly decent and much cheaper option is Apple TV; it's what fboab uses. You have to put up with the remote though - which is the very work of Beelzebub himself. She has hers connected to a 32" TV, and it's just fine - very slightly lower quality graphics compared to my PC, but still more than satisfactory.

Ah yes.  I'll have a Mac Pro in the bedroom which should handle VR graphics and could link that up to a wall-mounted TV via HDMI.

Just been looking at BigRingVR as an alternative to Zwift.  I'm not so interested in the social/group side of things (stereotypical anti-social miserable audaxer  ;D) and the BigRing graphics and routes look great.  They even have my favourite Tenerife Teide climb! Oh - and it's cheaper  ;D

I'm starting to really "enjoy" the TrainerRoad sessions on the Kickr (thanks Duncan!).  I suspect my FTP was measured a bit low at 223 so I've found the first few weeks quite easy.

However, one thing that has come to my attention is cadence.  For years I've been grinding away at (probably, never really paid much attention) around 70-80, and 65 on steep hills.  On all the TR session in ERG mode I'm quite happy doing threshold intervals at 90-100.  Hopefully this will translate to road riding, at least to some extent.

Another really useful thing is being able to do long periods on the tri-bars.  I'm using the bike I do audaxes & other long stuff on so the setup mirrors real-world conditions and this will hopefully reap rewards too.

All in all, is some ways this turbo stuff is turning the lockdown from what could have been a minus into a bit of a plus.

Have done four rides on the elite turbo muin b+ as a complete novice.  It doesn't take data from Zwift so I tend to stay in the same gear and watch the grades and speedo.

It's moved my ftp from 230 after ride 1 to 251 ride 4. What accuracy this has I don't know but the speeds seem right for me on climbs - lowest so far 5km/h! Biggest incentive is competition with other riders, I had a long tussle with a Brazilian rider in Harrogate. He was stronger and more skilled but I made him work for his ultimate triumph.

I want to climb Alpe d'Huez next but it's locked - level 6 and I am still only a 5.

Wonder how long the virtual rides will count on the challenges.  Cant be bothered about Zwift, prefer to get a kicking on the hills using the the trainer.  The turbo came with 2 years sub for Elites myE training.  Has 50 training videos you can pay for and 2k of free training videos to chose from, some brilliant and others crap. Last day of the challenge was Lac de estang, Murat to St Flour via Prat de Bouc and the Descent from the Pourtalet to Biescas.  The descents are crap on the interactive trainers still have to pedal.  Been down the Pourtalet on the tandem, hit 90km/h and hardly turned a pedal.  The descent is well graded and hardly any blind corners. Today its the Soulor and Aubisque then hunting thro the videos for the Pyrenees and Massif Centrale for more nice cols. 😄

Post by: Asterix, the former Gaul. on 02 May, 2020, 10:55:09 am
I don't mind that descents are only perceptible on my trainer by looking at the speed.  One advantage is that I don't spin out and 85 km/h is not unreachable. 

One day I will pay a lot more and get a trainer that will do what Zwift tells it to do!

I'd a fantastic descent down the Aubisue but it's best to slow it a bit through the tunnels:

Is there any correlation between an indicated speed/distance on a turbo to #reallife. I have an very basic and fairly old turbo with a resistance lever on a cable. If I stick a cycle computer on the rear wheel. Well on the handlebars but reading off the rear wheel obviously would this be at all accurate. Unfortunately I don't have any way of measuring power to compare against on the road
Title: Re: Turbo trainer
Post by: DuncanM on 03 May, 2020, 01:48:18 pm
Some turbo trainers publish resistance curves. This would, in theory, allow you to calculate power from speed (and resistance level if it has variable resistance). Unfortunately, the error margin is enormous - tyre pressure and how hard the drum is pressed onto the wheel make a massive difference.

However, if all you care about is measuring improvement/effort, you don't need one of those curves. Just keep the tyre pressure the same (ie check it regularly), don't adjust the drum settings, and record how fast/far you go. If you are going further in the same time, and all else has remained equal, you are fitter. This is essentially the method Graham Obree used when he was breaking hour records (he basically did a 30 minute TT every week on his trainer to see if he could go further).

Yes I think that will be the answer, I got it going after a bodge where you connect via the companion app on the phone, even though my laptop could see the tacx Zwift thought BT was constantly turned off. It seems a bit flaky so I've ordered a dongle.

On another note, jesus wept how complicated is Zwift, I need an instruction manual or something. I can't seem to end a ride without it closing the game, the only option I get is to "save and exit", if I press "back" I just go back to the ride and not any sort of main menu.

Still managed some sort of training, I'm not exactly sure what but I was sweating anyway so must have done some good. I've a long way to go to get the hang of this and make any sort of productive/structured use out of it though.

If you have a smart turbo then I think that the turbo does the math and sends the power data (probably with speed and other stuff) over BLE/ANT to whatever software it's talking to (TR, Zwift, Sufferfest, whatever).
The only case where the software needs to do the math is where you use a dumb trainer and they are doing virtual power (and the chances of that being accurate are remote).
Title: Re: Turbo trainer
Post by: ElyDave on 17 May, 2020, 06:01:24 am
Correct, the power based speed from my StacZero that gets to the software is way different from that indicated on the Garmin display. Tbh I should probably stop using g the Garmin as well, it only creates issuesvwith multiple tracks.

I'm not sure why this is as I think/thought the StacZero used power to derive speed, but it also has a wheel magnet, so is clearly sending both bits of data. I've not really played with the road feel settings too much, but I do seem to be in a higher gear than the indicated speed would suggest

Post by: giropaul on 17 May, 2020, 08:29:27 am
Unless you have a properly calibrated power meter the information going to the i-platform are always going to be guesstimates. This doesn’t matter as long as you don’t change anything, you will still be comparing yourself against previous results, and hopefully tracking improvements.
During lockdown a group of riders who previously attended Wattbike Classes are having fun with some 10 mile TTs etc. Some are on Wattbikes ( rented out from the studio) but others are using various smart or dumb trainers. I know their FTPs etc from before lockdown, and some data now is wildly different.
I know that some take i-racing seriously, but the same issues exist - and I gather that it’s not unusual for riders to use clever manipulation to their advantage.
If you haven’t got an accurate power meter, your pulse rate is the best available indication of power - slightly lagging behind the effort level though.

the StacZero is based on a calibrated powermeter, I belive the power numbers coming out from it, the speed algorithm is somewhat irrelevant. I'm only curious as to why it is so different from the wheelspeed

Unless you have a properly calibrated power meter the information going to the i-platform are always going to be guesstimates. This doesn’t matter as long as you don’t change anything, you will still be comparing yourself against previous results, and hopefully tracking improvements.

Yes I didn't expect the power to be anything like accurate enough to not take with a pinch of salt, I was more worried I was a country mile out because I'd potentially failed to input any wheel/tyre size but that seems a non issue.

On a further note I'm really enjoying Zwift now I've got the hang of it, I've finished sessions on there at an effort level I've never been close to on the road, for one reason or another.

What I seem to be finding when doing a higher intensity is that I'm not getting severely out of breath or an overly increased heart rate, it always seems to be lactic in the legs that has me backing off, where as with running it is the complete opposite, the legs feel fine and it's just due to breathing through my arse on the verge of collapse that I have to stop.

I had a really weird experience yesterday. I signed up with Zwift, meaning to do the clubrun (as a meetup, obviously). I tried the introductory "hilly loop" a day or two ahead, for familiarisation, but got called away to real life before I'd finished, so left the ride part-done. I didn't have enough free kilometres left, so I paid before the run.

Yesterday, I clicked on the meetup in Zwift and was whisked off to another world, but it was back to the hilly loop. I was getting some updates from the meetup, but not many, and I couldn't see other riders. So I ended up doing the loop again, by myself. But I ran out of timed meetup (for the clubrun - I could see the remaining time) before I'd finished the loop. So I reckon that every time I go back into Zwift it will be groundhog day on the hilly loop, and I'll never finally finish it.

I can't seem to end a ride without it closing the game, the only option I get is to "save and exit", if I press "back" I just go back to the ride and not any sort of main menu.

I think this a feature rather than a bug. The aim, I think, is for Zwift servers not to be overloaded by people logging on, switching between rides and never logging off between rides. Ending a ride forces you to log off and presumably freeing up server bandwidth for someone else until your next time.

BTW 1, take a look at zwiftinsider.com for interesting information on Zwift.

BTW 2, I've also been trying RGTcycling.com which is kind of similar, not as sophisticated but it is free.

INCOMING!

New motherboard for the dead Drivo incoming from Elite SRV tomorrow.  :thumbsup:

Can't fault the Support experience so far; especially as they're located in Covid-Central, Italy.

I think UK has taken over the mantle of covid-central! 

Good news, though.  Hope it fixes the problem.

Indeed! Although....

I rode outside today.

Wrong time to be asking, but once we're allowed to travel again (I'm trapped down in SW Wales)...

...are there any bike shops with a selection of demo turbos to try? Mainly smart ones.

I know Tredz in Swansea -currently covid closed - have one direct drive set up; I'm wondering if any further afield have a bit more choice.

If so, I'll probably struggle on with my knackered old fluid trainer until such time as I can go try a few out. Otherwise, I might as well just hunt stock on-line for now. It's a lot of money to drop for me and so I'd like to maximise the chances of getting it right first time...

Probably a bit far for you but Palace Cycles in Carlisle had a whole room filled with every model of Tacx trainer with bikes and computers/iPads for you to try. Mind you, they probably sold them all by now.
