Chroming is generally a bad thing but looks pretty.

....Hydraulic disc brakes have their problems but they make sense on an MTB.  On bikes with dropped handlebars disc brakes make less sense anyway and hydraulic discs are appreciably more difficult to set up, needlessly expensive to buy and run, and far from immune from other difficulties.
Sigh, you were doing so well, Brucey, until you brought your prejudices regarding discs on drop barred bikes into it...

and you have no 'prejudices' then?

Read what I wrote carefully and you might see that your reaction is more to do with your prejudices than what I have written.

It is self-evident that disc brakes make less sense on bike with dropped bars, else more of them would be so equipped, eg in the pro peloton.

Ditto hydraulic brakes for other applications, e.g. touring.  It should be obvious that hydraulics are off-putting to many folk, else (say) Maguras would have been more popular over the last 30 years or so. 

I agree a lot of mechanics have yet to become 100% au fait with dropped bar hydraulics but (amongst other things)

a) I harbour a doubt about the fundamental layout of such MCs; I don't think that they are intrinsically self-bleeding in the same way as in some other arrangements

b) there is not enough flexibility in the system; once you have hydro STIs you are pretty much tied into using the gears and brakes that match them, and nothing else will do.  This limits choice and also sounds like a fast-track to built-in obsolescence.

c) there are not many spare parts available; if your hydro STIs go bad, chances are that you will have to replace them. Parts and labour for such is about the same cost as the cost to buy an entry level road bike outright.

d) you have several hundred pound's worth of kit strapped to the handlebars right where it is most likely to get clouted  in the event of a prang, or even a parking knock. Ordinary STIs are bad enough but hydro ones take it to a whole new level.

Many of the above (and more) may well be corrected in time. But right now, to a lot of folk, systems of this type look more like a load of faddy nonsense than anything else.

£30 for pads?  I hope that's for both bikes. I've been using for a good while now.

After market options don't yet appear to be available. That's £30 for two sets from the cheapest possible Euro supplier that I happened to be ordering a dynamo light from! £20 for one wheels worth rrp. "But you save on rims!"
I'd ask the same about steel frames for all but long-distance pan-continental touring

Because I don't like fat carbon and aluminium tubes on a bike and like the ride feel you get from steel

Which is all fine. I'm not going to tell you what you should like riding.

I like a nice lively frame that responds in a snap to efforts and doesn't feel like it is absorbing energy. I've had loads of frames, 4 steel, 3 Ti, 5 Alu, at least 7 CF.  They all rode slightly differently especially the CF, in terms of comfort and responsiveness. One of the most fun to ride is a fat-tubed aluminium. I haven't missed any of the steel ones at all. But that's me. I ride in a certain way, for certain distances. I have certain requirements, but not others. My bikes are never subjected to being bashed about which would concern me if I had a CF bike with pencil thin stays.

Thru axle, to be honest it's nothing major, just accentuates the other rub. Going to try more delicate rotor trying and check the front hub is all as it should be. The bike is only just over a year old with little use so only changed the front pads so far, made sure poisons were pushed well back and that's when I gave up on the rotor trueing and just left them to bed in a while.

Sexual dimorphism, that's the term I was looking for.

I think Sky have given us enough rope with the known facts, without the need to resort to speculation.

That doesn't really make any sense at all. It is speculation that has caused the rope to be given. If there hadn't been speculation about possible contents of the jiffybag there would not have been any interest in pursuing the case. The 'jiffybag' leaker speculated as to the contents.

I am surprised but I guess it’s a very personal thing. In my time, I have ridden steel bikes by Mercian, Condor, Woodrup, Arthur Caygill, Colnago, Dave Yates* and Shand. All have been, and some still are, a pleasure to ride. All but the Shand are horizontal top tube, lugged brazed frames, the Shand has a sloping top tube and is TIG welded.

* actually built by me on Dave Yates’ framebuilding course.

Can I ask if the bike is thruaxle or QR?
I have had ultegra di2 hydraulics with both and the QR was a constant battle with rub.

I found that there was an optimum tightness which held the wheel but did not stress and warp the carbon.

If they are thruaxle then something is wrong with the system. Taking the wheel out and back in with thruaxle is a joy. No checking for alignment or fit. Once the axle is in they are centred and rub free. I would find a good bike shop.

I apologise to all the great mechanics on this site but I think some road bike shops are relatively inexperienced with the road hydraulics.

I think in the UK the only Super Randonnee recognised by ACP would be the Cambrian 6C, if done in 60 hours
