Which Groupset?

who are we talking about here? Dov o Neil?

BITD maybe.

Aren't pictures of bike parts breaking purely anecdotal? Surely anything will break with enough mis-use or even just a anomaly that leads to failure. Until there's a mass of evidence then it's just down to the individual user no?

Pretty much.t'interwebs full of failed this, failed that.

I've torn the left hand pedal, from two completely different cranks, in the space of a couple months. My left leg is fecking awsome though.

Red had a rep for saving too much weight on the chainrings, and the front mech though.

"Saving too much weight".. lolz

You know what I meant...

...oh wait...... look at this DA 7900 crankset.......OMFG...... DA will kill you......in the face......with fire....

Fiddled with an Ultegra Di2 display bike at lunchtime fro first time, the shifting very impressive but the levers felt really flimsy compared to standard carbon Ultegra and I don't know if it was the set up but there was some weird ratcheting/stepping thing going on with the brake cables.

Verdict : sort of want.

^ that sounds like a badly cut brake cable.

I had a go on the Ultegra Di2 last week, it was strange. It shifted instantly and I think would take a bit of getting used to, I'm going to stick with Sram for now but if I find/win a load of money I'd get a Di2 group set, just for fun.

Neil, Ultegra di2 test bike in at Edwardes. Nice and local.

11 speed dura-ace..so many choices so little time

Will the 11 speed DA be di2 then as well?

You can wait for the next big thing forever though.

Current Di2 is very simple compared to Ultegra Di2 and all future varients due to them moving to Canbus signalling.

So the DA Di2 is much easier to modify- for example putting the battery in the seapost.

^ i found it very good but would defo take a while to get used to..I like to 'hang a gear' sometimes then change.. didn't seem to like that on the test version in the shop, but probably just a matter of getting used to it.

If i had the money I'd go for Ultegra di2 but at the moment a £400 second hand Red gruopset going to have to last me.

Would there ever be a wireless gear system? Surely something like that makes sense?

Well on the one hand everything else has gone wireless, but on the other hand there is the matter of power- Di2 has one battery, if it was to go wireless it would need 4.

4 more things to go wrong

Judging by the latest PX newsletter they're gonna do a deal on Ultegra di2 next week.

Also not to mention 4 batteries to recharge...
well I guess the upside is if you wanted to you could hack it so you could shift your opponent's bike into the big ring as a hill is coming up hehe

To get wireless to work and overcome channel clashes you'd have to make each rider's transmissions unique in some way. Riders could 'sign' their transmissions with a code known only to them, and the derailleurs would have to verify that code on each shift. This would require some kind of code entry system and interface. Fancy plugging your bike into your laptop, or using some kind of display like the Di2 Alfine?

It would make it all massively more nerdy.

Tech already exists though- ANT+ for example, for wireless SRM's to speak to their specific Power Control.

One consideration is whether you will be working on your kit yourself, or paying a bikeshop to do it. SRAM kit is certainly a little fiddlier to work on, especially when it comes to replacing cables. I have been running a Dura-ace groupo for 5-6 years now and I seriously can't fault it. It's never let me down and is showing no signs of doing so any time soon. It is a personal thing though, and you really need to have a go on both before deciding.

Or just accept that they're both excellent and that you'll get used to whatever you buy.
