I've had my 2006 CRX1 for about a year; what a great bike! I did have a problem at first with the Truvativ Elite compact crank, it started creaking and then went loose, ie, you could move it laterally. The bike shop got a replacement which was also an upgrade to the Rouleur, not had a problem with it since. I had the Utlegra 12-27 cassette from the start, great for getting up the hills! and not had a problem changing gear. I swapped the Easton stem for a BBB High Rise (35 degrees). I use it nearly every day to commute and weekends too and estimate it's done about 4000-5000 k's. I've had Conti gator skins on which were great for puncture resistance but now have Conti GP 4000 700-23, BRILLIANT! I love riding this bike and I'll be sixty next year but still manage to "burn-off" some of the young-uns on it!
