Looks like they've changed the rules on handlebars, which in previous editions banned all tribars. The 2019 English rules say:
Handlebars extensions are allowed only if they do not extend beyond a line created between the front of the brake levers, which must not be pointed forward.
However the French original says:
Sur les guidons dits « 3 positions ou course » les prolongateurs avec repose avant-bras sont autorisés à condition qu’ils ne dépassent pas la ligne passant par les points les plus en avant des poignées de frein.
Which Google translates it as:
On handlebars known as "3 positions or race" extensions with forearm support are allowed provided that they do not exceed the line passing through the most forward points of the brake handles.
In any case, doesn't look likely I'll be able to get my bullhorns past the bike inspection which is a bit boring.
-
no tt bikes then.. ::-)

Any news on Unicycles?

Two or tree wheeled bikes only.

So it's the same rules as in Olympic triathlons. Nothing longer forward than front of brakes.
These (https://www.chainreactioncycles.com/dk/en/deda-elementi-carbon-blast-clip-on-aerobars/rp-prod84204) will be legal, just like the good old spinaci.
-
I've seen (on PBP videos) Spinacis in use, masquerading as bar bag supports.
In any case, doesn't look likely I'll be able to get my bullhorns past the bike inspection which is a bit boring.
That was a major reason I didn't enter a 4th PBP (they brought in the handlebars restrictions after my 3rd, 1991) and by then I was using 'bullhorns' (not a word I like) as I have done ever since.

But it looks like bullhorns may only be a problem from now (depending on how you read the restriction).
I had no problems with my bullhorns in 2011 (http://www.greenbank.org/audax/pbp_01.jpg)

Phil Chadwick used similar as well. Can't see that there should be a problem with your 2011 set-up; doesn't look like the bars extend beyond the front of the brake levers...
-
I think "3 positions or race" must mean road drop bars*, so it's not saying much at all about any other types of bars.
(reading the French rules strictly, flat bars and full length aero bars should be allowed...)
-
I would like to see some clarification on flat bars with bar ends as I intend to use a touring bike with such a configuration.
-
As I understand the french rule they are only talking about "guidons de course", which are drop bars in anglo-saxon. I would have thought that bullhorns should be ok, your hands are next to the brake levers. I don't know what the rules are on flat bars with horns but the situation is not as extreme as tri bars; perhaps they couldn't complain about stubby extensions that don't come any further forward than the handles of the brake levers.
-
Those folk in Quattrovelos are going to need special dispensation.
Indeed, that has already been discussed at the relevant level.
-
The intent of the number of wheels limit is to prevent rollerbladers and suchlike from participating. Same for the 'chain drive' requirement after Alpo on the Kickbike at PBP03. Belt drive bikes were nodded through, of course.

Where's the fun in that?
-
Reading that, wouldn't bullhorns be ok, along with draft legal aero bars? The bull horns don't extend beyond the brake lever...
Looking at my current bike, I could lop off about 15mm off the front of my aero bars, and they wouldn't extend beyond the limit of the brake levers...
Maybe I won't need to buy a velomobile before 2023 afterall...

Have you tried overtaking a rollerblader while riding a bike only slightly quicker? Now imagine doing so while both people are quite sleep-deprived...

Fit handlebars with long ramps to push those brake levers further out and you won't have to trim the aerobars.

Our Chairman, Chris Crossland, is travelling to Paris this weekend for the annual "presentation" from ACP. It may be worth asking him to see if he can get clarification on any points that concern members. It's probably best to email him at chair@audax.uk with any specific questions to ask.

Especially as there are also a few informal sessions with ACP representatives around that meeting.
I'll be there as well, representing Randonneurs NL

That depends. If it's a rolleblader with a good technique, usually someone with a marathon speedskating background, then it's not such an issue. If it's someone with an ice-hockey style background, that's a completely different problem.
-
That bit about "must not be pointed forward" is completely absent from the cited French spec. Seems like the translator added it gratuitously.
Chum of mine had no problems with bullhorns in 2007 or 2011. His brake levers point backwards, though.
-
Prior to the 1995 PBP we (on behalf of AUK) sent ACP a sheet with several sketches of possible handlebar configurations, for their comment. Included were bullhorns, straight bars with extensions at the ends or inboard, short and long tri-bars, butterfly bars, I think there were 8 sketches in total. They returned the sheet with all the sketches crossed out except the standard road drops.
That was then of course, things have obviously moved on since. It was probably one of those situations where it would have been better not to ask the question.
-
I would like to see some clarification on flat bars with bar ends as I intend to use a touring bike with such a configuration.
I rode flat bars with bar ends (not extensions, per se) in 2015 and Eduard (bike check) raised his eyebrows and nodded it through. If he had said "non" then I would've removed them there and then and probably refitted them up the course somewhere, as they barely showed forward of the bar, being mid-mounted.
However, he may've been raising his eyebrows as much at the bike (https://www.16inchwheels.uk/2015/08/20/paris-brest-paris-a-fold-of-bromptons/) as at the bars ;)
There was a mountain bike tandem that I drafted for a while, and they also had bar ends ISTR.
It was probably one of those situations where it would have been better not to ask the question.
This.
-
I rode my mountain bike with multi-position bars in 2003, the bike checker called for an adjudication on seeing them and the adjudicator just waved them through. Each time I've ridden PBP I've seen a few people riding flat bars (with or without bar ends) and I can't imagine that they would suddenly be banned this time. It's just tri-bars they don't like, however in trying to provide a quasi-legal definition of a tri-bar other configurations get included. Fortunately the officials take a very French attitude to regulations and ignore them.
-
I have just watched bits of a YouTube video made by Idai Makaya, riding PBP 2015 on his Elliptigo bike. It looks very much as though he, and his comanions, are using the same Ergon grips that I have. They obviously got through the bike check.

Isn't there a different set of rules for recumbents etc starting in the special group? You see plenty of them on PBP and almost none of them have drop handlebars.

In theory, no difference. In practice, the French are pragmatic at PBP.

No penny farthings then. :demon:
-
Only one high bicycle has ever ridden PBP, back before audax or randonneuring existed and the time limit was 10 days then. It would be a real athletic feat to do PBP on one. The End to End record is a little over five days, so doing not too much less distance in under 90 hours is a bit of an ask, even with better roads. If somebody entered who had a decent chance of actually doing it, the organisers would cheer them on.
-
The chain drive requirement would rule out rollerbladers whatever the number of wheels though.

I don't understand 'draft legal clip ons' link to example appreciated.

there was (at least) one who've done it on a kick scooter - no chain drive. perhaps a personal exception?

The normal Cinelli Spinaci or TTT Tiramisu don't have connected ends, so they need a separate bridge to join them.

This is something that wasn’t clear in the regs. Do they have to have connectors?
-
The connector thing for draft-legal bars is based on the comment upthread that it is the same as for triathlons, which at least would be justifiable consistency. I don't actually know whether the PBP bikecheckers would reject unconnected Spinaci bars.

Awesome, many thanks for all the suggestions. Let the investigation commence!

Anyone fitted these short bars? Not convinced they'd work for me.

I found titchy aerobars more trouble than they are worth when I tried them a couple of decades ago but I am >180cm tall with forearms to suit and prefer to have the pads close to my elbows. An Oompa Loompa would probably like the little ones though.

Currently £5. Worth a punt.
Although I notice it states quite a small clamp diameter. Suck it and see.

Yes I have long limbs as well and suspect that to put my wrists on the pads would be very awkward indeed.
-
Well,as I’m too sniffly to be doing Benjamin Allen’s Spring Tonic, I’ve had a little tinker with the trike.
It’s now sporting Tiramisu bars! They are very short. I’ve not ridden with them yet, but the advantage of the trike is it’s very easy to hop on and see how they feel. I suspect they’ll be most comfy if I don’t hold them, but rest my wrists on the ends, kinda like the ‘virtual bars’ position people used, but with a bit more support. I’m definitely going to need to double wrap my bars, but I was planning on doing that anyway.
When I’ve had a play I’ll report back.
They will be very useful for supporting a couple of feed bags, so they may stay on even if it’s only for that purpose.
-
It always makes me nervous when I see pros using the "virtual aero bars" position at the front of the Tour de France peleton.
I wonder if ACP are allowing these short aero bars to avoid potential catastrophe due to riders not actually holding on to anything and maybe bringing a massive bunch down if they hit a pothole?
I might try some myself. I had full size aero bars on in the 1991 PBP, the last time they were allowed, but one of the bolts holding an arm pad snapped early on, so the aero bars became a non-aero luggage rack for the rest of the ride.

This is what I'm planning. Deda Parabolica. I bought an extra set off ebay so that I could use 2 clamps on 1 set and put the pads just behind the bars.

This is good news. Now where did I put my 150mm stem... :thumbsup:

Thanks for the inspiration @ John, Diesel. I just took these off ebay. I have old style 26mm bars from a 1984 Dawes Galaxy. Not sure why the description says "Standard" 26mm. Is standard not 31.8mm these days? Never owned a bike made after the 80s.
If they are too long I intend to cut them back.

Have you been coping with this setup? I have ridden with my setup quite a bit. I do like it. However I have yet to cut the bars to brake lever length and fear they’ll be useless after. I do also miss the lost hand position on top of the bars. Saying that, I’ve removed them now and my body naturally wants to fall on them when riding. Quite a comfy luxury!
-
This works for me, have ridden up to 300km so far with this set up.
It is compromised, not where I'd like it to be but seems to be ok.
With my setup I can just use the tops still but don't often.
400 and 600 coming up so will see how it goes there!

Thanks, please do keep us updated.

Dear All
With about a month to go, I am finding that my hands wrists are really playing up when I get to 600km +, so I welcome the idea of of the wrist rest rule. I have tried a few events with them and have stacked them quite high, so loose any aero benefit (I am much lower than when on drops!) but importantly hands 'ok' at the end. However, being a very slow adopter, I am on old fashioned shimano slr brake levers and not sti levers as I used single speed and fixed. This causes a bit of an issue, as these are very short compared to STI levers , by about 4cm.
The sti levers tend to have their levers pointing down so the rubber bits are the most forward part of the brake, and my old fashioned levers have the tip of the levers well forward of the top rubber bits in a intended use normal set up. , not tilted in any funny way.
I have read rule 8 on bikes etc - what is the consensus on where the front of the brake lever is - top handle rubber bits, or tip of lever? If this sounds like overkill, it is because I have long arms and the last 4cm will really count so i don't keep banging elbows and pads etc on knees if i mount further back.
I could of course just buy some second hand STI levers and not use the gear bits I suppose..... but my brake levers are not broke so no need to replace yet!
Any thoughts?
-
My read on the new tri bar rule is whatever part of the break lever is the furthest forward counts, so it could be the bottom of the lever or the hood depending how the levers are installed on the handlebars.
-
And it's easy to control. Just take a spare arrow, hold it in front of the handlebars and check what object touches first
-
if i install bar end shifters on the tribars, i suppose the measurement will be from the shifters (and not where the tribars start)?..

Thanks everyone - feel like winging it, but not sure will get a reply from france!
Hopefully photo inserted to show my point - tribars set up in line with brake lever tips - camera angle may not show too well

Not doing PBP, but have got my bars sorted for TCR:
(https://pbs.twimg.com/media/D-sqpbfXYAE6EIX.jpg)
I need to fettle the position of the right hand aero bar, it's slighty twisted. I'm loving having the di2 shifter on the bar end...
Yes I know it looks bloody weird, yes I know I could buy something with the right sort of shape, but the base tt bars were €20, and the bar ends were €10. The bullhorn base bar was rather more...

I've found that I'm a lot more comfy doing a praying mantis with my elbows joints on the pads, palms down on the tops of the j bends. I only tend to actually grip the sticks on moderate descents and when putting efforts in to get up small climbs. Considering getting some kind of TT bar end plugs that I could grip more comfortably, like the size of squash balls.
And yes I know the bar tape is unequal 😬

I have now got used to my bar extensions after a few months. Couldn't spend long in them at first but now am on them most of the time. Not modern aero versions but will relieve any prolonged hand pressure which is main concern.
-
Not doing PBP, but have got my bars sorted for TCR:
if that's your preferred shape, there are profile jammer gt extentions that look neater and would be lighter too
-
before people get carried away - the discussion here is not whether tribars work or not (they do), but how to set them up in a pbp-compliant way and whether it's worth it (it depends).
-

Yeah, there's bars out there that are close to the right shape, But considering I got these for €20 (including the bar tape!), and added €10 bar ends, It's hard to beat on price. Not sure it's worth worrying about the few grams I'd save in terms of weight, Also the setup I have now works well for strapping a bag too.
Maybe when I have another job, I'll experiment, but for now, these work for me. I'm loving having the di2 shifter on the uprights. Being able to shift from the aero position is amazing! They would be PBP compliant if I was to cut about 15mm off the end of the horizontal too...

Bullhorns might allow you to use longer extensions (or not cut them down as much).
Shifters are less of a problem if you're using Di2 (or fixed). I didn't mind losing the drops as I rarely used them, much prefer aerobars for headwinds.
Compare these two for example and see how the aerobars don't stick out as far past the brake levers with bullhorns:

was playing around and testing different options today:
found a comfy setup that works, only the levers have to be opened forward (alternatively - a longer stem):
The rules say "Handlebars extensions are allowed only if they can't extend beyond a line created between the front of the brake levers, which must not be pointed forward."
Probably a good thing because my 2 foot long brake levers were a bit of a hazard.
-
The "must not be pointed forward" part doesn't appear in the French rules.
Sur les guidons dits « 3 positions ou course » les prolongateurs avec repose avant-bras sont autorisés à condition qu'ils ne puissent pas dépasser la ligne passant par les points les plus en avant des poignées de frein.

What do they mean by not pointed forward?

They are still a little bitter about Agincourt.

I had almost given up on the idea of using aero bars for the PBP because I couldn’t stay on them long without lower back and hip pain. It was also difficult to mount my lights as they need to be the right way up and would normally go in the same place the arm rests have to go. With the Mersey 24 hour TT coming up I decided to make a few changes to my bike including flipping the stem to raise the handlebars about three inches and then refitting the aero bars. I tested the new set up on Sunday on an easy DIY 200km and found it made a huge difference. I could stay on the aero bars almost all the time without any discomfort and the kilometres flew by with little effort. I’d only just recovered from illness and been off the bike for two weeks yet did my fastest ever 200km!
The bars are full length so too long for PBP but after the Mersey 24 I’ll fit some short ones that happen to be the same diameter into the same arm rests. As for the front lights, I have zip tied and taped them to the side of each aero bar so their beams are directed nicely onto the road ahead. I’m planning to test the new setup including lights at the weekend with another DIY 200km ahead of the 24 hour the following weekend.

all drop bar levers point forward if they are set up correctly, the question is how much forward is still usable/rideable.

bullhorns are an option, but i like riding on the drop part and use it often. one other option would be to use long reach drop handlebars, but i can't stand the shape to actually use them.
-
I think the intention is that you cannot provide a placement for your hands which is further forward than provided by the brake hoods. They have picture of “within the rules” tribars on Facebook. If people start pushing the boundaries officials could become pedantic. My tri bars don’t extend beyond the brakes but they are capable of doing so if I adjusted them. They therefore might break the rules depending on how you interpret “puissent”
-

Standard mounting for modern STIs has them pretty much vertical (https://www.facebook.com/ParisBrestParis/posts/10156534970378780). Mine point backwards because they're set to minimum reach.

it's one of the uncomfortable shapes of the bars i was talking about earlier, with long ramps sloping down. with ergonomic handlebars brake levers are slightly forward (at least when set up the way i like it)

It's worth thinking how you might modify your handlebar setup if you get Shermer's neck. I'm a bit concerned that riders are trying to limit the strain on their backs. The shock absorption given by the back, when arms are not locked out, will be transferred to the neck muscles.
Here's an article where a RAAM rider turned his aero bars through 90 degrees, and the problems with that.

I have stayed out of this discussion as I am not a tri-bar user. Most of the people who I have ridden with who use them are not aware that they weave around and make close group riding impossible. There are some exceptions who can ride in a straight line, but that is not common in my experience. If you must use these then please use them after the large groups have thinned out.

Inspired by this thread. Two cheap aerobars used - some modifications still needed but mainly ok. I added bolt to keep arm pads in right position and don't have to tighten too much.(https://uploads.tapatalk-cdn.com/20190711/da61a8db8254410a4085b1d870fda106.jpg)(https://uploads.tapatalk-cdn.com/20190711/6bd639dad94aa2e9ef0da3846cf60465.jpg)

Did any of you guys who used tri bars have any issues at all during bike check?
Did any of the bike checkers actually measure forward extension? Did they just eyeball it?
Was anyone asked to move/adjust tribars to make them compliant?

Bike checker eyeballed mine, then checked other things, then eyeballed mine again...then produced a board with a a spirit level screwed to it and announced "2mm". 2mm??? WTF?! I'd measured pretty carefully and can only think the 2mm could be because I'd done a pretty average job of tucking the bar tape into the end caps when retaping them the week before. Out came the multitool and I rotated them an infinitesimal amount which seemed to make my checker happy, no further spirit level required, waved onwards.
Talking to others (with aerobars plainly further forward than mine) I was particularly unlucky and they all just got eyeballed and waved through *sigh* so much for the scientific approach turns out it was luck that you got the one guy actually checking properly.
Wouldn't have been without them though; hands were fine at the finish. :thumbsup:
-
similar experience, the controller showed my aerobars need to be in line with the hoods. i showed that they are inline with the levers. then he took a spirit level board, measured against the hoods - "see?". i was about to get my allen key out, but he said "it's ok, good luck".
-
I didn't, but the Australian next to me did. I think it might be because I took the advice on this forum and tried to speak French to them. They voluntarily switched to English so obviously I wasn't that good at it.
-
Seems like there are a variety of experiences
I had a very quick bike check and I didn't notice them even look at the aero bars.
I also noticed one person ahead of me in my start group who hadn't moved their aerobars for the event, they protruded quite a way from the hoods.
That said, the short aerobars worked really well for me. No numbness of fingers and shoulders/neck were fine.
I did find though that using the aerobars limited my ability to join any groups. as I won't use them when I'm behind someone and I wanted to use them extensively.
Ironically, having put the aerobars back to their previous (long/regular) position this feels less comfy now! having spent 6 months getting used the the shorter configuation. But they are off the bike now and not planning on using again for a while.
-
Yes, quick check of extensions with their hands, but all good. Then lights. Then checked bottle cages. Then tried to stick the pass sticker with my number on the wet frame. That sticker didn't stick for long.
-
Presumably some pioneering engineer will come out with a set of aero bars that pop in and out like those collapsable police truncheons you see on The Bill.
-
or you could have clip in bar extensions like the ones on the massive sword in Highlander. The extra bits sit in your luggage till you are out on the road and get put back before entering any control.
-
in a similar vein one could bodge two mini pumps instead of the usual extensions.
-
My bike was thoroughly inspected: mudguards, bottle cages, brakes, lights (even had to show the backup rear had a non-flashing mode). No attention at all for the aero bars. Which ended forward of the brake hoods but did clear the levers. And the Berthoud bag protruded at least an inch.
-
Thanks - very useful as I start experimenting with tri bar setups. I'm getting a bit fed up of the continued tingly fingers/loss of strength since PBP and need to find something more comfy. Trouble is, at the moment, I am struggling to get a "compliant" position (not that it really matters for another 3 years, 344 days).
-
I thought the inspection was fairly cursory; checked brakes worked, bags not loose, they turned battery front light on, rear light was already on from riding there in the rain, checked bottle cages not loose - nothing serious really. Chap I cycled there with had to move his rear light from seat stay due to bag obscuring it too much.
Apparently there were long queues earlier in the day and maybe they'd been given the hurry up. I turned up a bit late and there was almost no delay.
-
Didn't have my bags fitted for the bike check. Maybe that left my aerobars as the only thing to moan about. ::-)
-
I expected lots of measuring as mine was within the rules but like only by one mm according to my home made wooden plank and spirit level. And maybe questions about my light mounted on it and protruding quite a bit.
Though there was a Corsica frame badge lingering on the bike.
The guy said Corsica?
Yes did my qualifier there,
lots a people?
Nah the two of us rode round the island in 35 hour as our 600 qualifier.
We chatted quite a bit about corsica. And then he asked got a back light? brakes work?
Me wanny see? Him no its fine just grab a free bottle and off you go.
Must say it was late afternoon and I am rather fluent in French

The American lady who checked my bike was too concerned that my brake levers operated different brakes to what she expected to be bothered about my aero bars. They were PBP legal, but that meant that I couldn't use them for long at a time. I put the full length bars back on yesterday and could stay on them all day long.
