I ride about 80 miles a week. I've had the bike about 5months now. Best commuter i've had. Nothing really crooked. I don't use the canti mounts. I have Avid BB7 Road Disc Brakes. The derailleur is really strong. I once broke my SRAM Rival Derailleur once right by the bolt (I was in a really low gear going up a hill and a large but short stick got lodged in my derailleur) and the derailleur only slightly got bent. It was only a 5 min fix with a deraileur hanger alignment tool. Only think I didnt like was that the seat post binder is integrated with the frame and not separate.
Mine is a 54cm. I'm about 5'9" with 30-31" inseam.
