I don't know who BD83 is so I just want to mention that some of the riders in the 180+ range have had bad times with the Sid flexing to the point the wheel rubs on the for leg.

This was the early 09 version and effected the race and the team, and I hear they've changed the casting to make it better, just someing to check on, and I try to support my LBS, too- cause they can make it much less expensive in the long run.

Riders are fast, Bikes are expensive.
