Quick 23 mile blast around Woking and Guildford, and I have to say, I love the SRAM groupo. Doubletap just..... works, I didn't even have to think about changing my shift technique. And I'm a 175mm crank convert, maybe it's psychological, but being a fairly grindy rather than spinny rider, I'm convinced I could feel a torque advantage. Pedals do feel closer to the ground while cornering though. I got the indexing spot on first time, and the front mech only rubs slightly in top gear without trimming- I daresay that could be tuned out by accurately aligning it. Which is just as well, because I can't find the trim position!
And the major joy is the silence- the Microshift shifters (which I still rate by the way) clacked all the time, the Srams are silent. And silence makes me feel happy. And happiness makes me feel fast.
Also the shifter bodies are so comfortable, having all the cables routed along the bars makes it feel so uncluttered and open.
Overall, I like.
