Dolan Pre Cursa / PreCursa / Track Champion

I didn't understand that. I was worried that they wouldn't fit mine due to what you said. Re you using the strong light 107mm bb? Cause that's what I am using and it is as tight as fook, but it fits fine.

Hi JB,

I actually have two Stronglight 107mm BBs which will not work as the crank spider hits the frame (making turning the crank impossible).

In fact there is no way the cranks would spin with a 42mm chainline due to the very bulky spider on the 2000's. I had to get a wide shimano BB so that it would clear the frame but this pushed the Q factor much wider putting the chainline well out of whack.

The root of the problem is that the Pre Cursa (my one anyway) has very wide chainstays with clearance for 35c Tyres which is an unusual feature for a track specific frame.

Must get back to finishing this build as it is presently unsuitable to ride with and I have yet only rode it briefly once on a test tun which was in late November as seen in the photo below.
