and once the UCI gets its act together mechanical shifting is on its way out I reckon.
How are the UCI stifling the proliferation of electronic shifting? 😕
I agree they're not exactly progressive when it comes to technology, but AFAIK they've done nothing to halt this!
Some riders still use mechanical through choice (Cancellara?).
whoever said that electronic shifting will probably come to be cheaper than mechanical was spot on - hardly anywhere in product ranges is it cheaper to mass produce something mechanically complex over electronics. Whilst there will be mechanical groupsets in the lower ranges for many years to come, I would be surprised if shimano continued to make a mechanical XTR/Dura Ace for much longer.
The mechs still have to have all the same moving bits really, in fact the only bit you really get rid of is a spring, and you replace that with a motor, so arguably the same complexity but more expensive.
Shifters on the other hand change from a complicated mechanical close-tolerance clickety, ratchety, tiny-springs bundle of magic to a pair of buttons, so you have point there.
Sorry njee, for some reason I thought UCI disallowed electronic shifting.
Well then I'm even more convinced we will see top end mechanical groupsets die out in the next 5 years
I bet they bring out something like nexus di2 as well for the city bikes.
Non electronic shifting will be left to the BSO's and maybe deore for the expedition riders/cycle tourists and the retro crowd!

Alfine Di2 is already out there!

Believe Nibali prefers mechanical too, rode mechanical Campag SR I think at the TdF.
There has been a bit of Di2 teething troubles in the pro-peloton I think. Wiggins "parking" his bike at Trentino comes to mind.
Mine actually played up a bit soon after I got it, it would be fine for a while then take a good few stabs at the shifter to change down. A software upgrade seemed to resolve it. Did shake my confidence in it a bit but it's been flawless since.

Right, so Di2, hydro discs and belt drive - about as close to maintenance free as it's possible to get I reckon.
Have you actually used a belt drive, molgrips? 😯
Am I right in thinking that the Di2 XTR mech doesn't have a clutch?
Does seem to have a little gold thingy, but doesn't mention it in the specs, and it doesn't look like it's in the right place.

No, I read the thread on here, MTQG wasn't it? He got through a lot of belts, but that was off-road.
Perhaps I'd stick with chain and one of those fully enclosed floating chain covers.
That XTR Di2 looks like it has a clutch - the bit that says 'Dynasys II'.

See TurboFerret's ti commuter build!

Agreed, and the orange lever is in exactly the same place as the clutch switch on the mechanical mech.
yep, clutch controlled - as with the mechanical XTR you can adjust the tension on the clutch too. they reckon you can run the clutch tighter as the motor is more powerful, meaning shift performance isn't compromised... i wonder what chris porter would say 😉
motor disconnects in a big stack like the road ones do to protect it and lessen the chance of damage.

[url= http://singletrackworld.com/forum/topic/custom-ti-frame-thoughts ]Linky link[/url] for my interpretation of that, although I hope my belt has a slightly longer life-expectancy than MTQG! I don't anticipate quite so much mud on my London commute though 🙂
