Which Groupset?

where does sram fit in? except for Red being 'lightest groupset in pro peleton'?
Value = no
Ease of use = subjective but mostly no (DafuqTap)
Better design = no
Aesthetics = subjective/debatable
But mega hipster points

I've gone for Force rather than Ultegra on two of my bikes because:

1. It's roughly the same price as Ultegra
   
2. It's considerably lighter than Ultegra
   
3. Shifting devices are a matter of personal taste, but I get on perfectly well with Doubletap now I've got used to it
   
4. Aesthetics are indeed debatable, but generally I think Force is more attractive than Ultegra (and indeed that SRAM groupsets are generally more attractive).
   
   

The front shifting on the SRAM groupsets isn't as good as on Shimano/Campag (pre-Yaw shifters anyway) but on the Force groupset it's perfectly adequate if a bit sensitive to being set up just right.

I've got an Ultegra/XT mix on another bike. My own view, and again it's subjective, is that the shifting is better on the SRAM Force bikes. The lever throw on the SRAM shifters is less than on the Shimanos and there's a better 'click' on shifting. And I definitely prefer the braking with the SRAM brakes, although the Dura Ace calipers on the Dentist's Chair are very nearly as good. And the comparison's not fair anyway as the SRAM Force brakes have Swissstop Blacks in them, while the Dura Ace has Zipp Tangente pads.

Oh, and the winter bike's got Campag Veloce - at the moment the only one of my bikes to have Campag other than the Hetchins, and I don't think comparing mid 1980s Super Record with modern stuff is a useful comparison. It's nice, and the hood shape is excellent, but I still don't like the thumb shifter. Reminds me of my old Sora bikes.

Conclusion: First World problems. They all work, they're all roughly comparable in price and functionality if you compare equivalent groupsets, and each has its pros and cons.

The only real outlier is Di2. Bloody marvellous. Haven't tried Campag EPS yet, so I can't comment on that.
