BMC - tickling your fancy?

Really? My SL01 didn't budge an inch, I couldn't get it to flex in any way no matter what I tried. And the carbon seat stays gave so much more comfort over a fully aluminium frame that I often was worried I had a puncture as I couldn't feel all the bumps. It seemed to just get more stable at higher speeds and handled great. I would have another one in the right size by now if I hadn't ordered a custom frame.

Totally agree with the higher speeds thing. I even get annoyed with myself for being slow on the flats, as theres more fun in the bike that I'm not tapping into.

^ exactly, thats what I call comfort. The sizing was an issue for me as well, their 51cm has top tube of 50.5cm and 52 has I think 54.5, my ideal bike is 52cm horizontal TT

I think the small has a 53cm ETT. Still, bikefit is more than just ETT.
