Oooo.. me, me! It's a still a work in progress. Got it two weeks ago and tweaked it with some Doubletap 10, single lever shifters (awesome!), Conti GP4000s in 25mm, Ergon GP1 bio-cork grips, and the Brooks B17 Imperial I had on my previous bike. For whatever reason, the Brooks is more uncomfortable for me on this bike than any of my 3 previous ones, two of which I still ride. After my last ride I took off the Brooks and put on an E3 Form seat which I tried briefly before, liked, and stuck away for future use. We'll see how that feels. It's about 7 pounds lighter than my hybrid and you can feel it! It's nice to have both a hybrid and a road bike. I can see using them both with regularity. Mendota on the greenway, rail trails, etc. and Sirrus on the roads. Why does it have to get cold?!
