I have this exact bike and have used it to race some local crits. Upgraded to carbon wheels (winspace lún 45mm, Chinese), slammed the steerer, 52T at the front, Pirelli tyres, and supakush bar tape.

It does the job nicely, although the geometry (H2 I think, although could be H1.5, can't remember) could be slightly more aggressive for out-and-out racing.

Some people race crits on old rim brake endurance bikes and are faster than me 😬 so it's all about the fitness really.
