Yeah, that was a real pity. The best thing about the flat CG races is getting into a group, staying with it, then having a race for the line at the end.Well that was annoying - had formed a group of 3 out front at halfway with Bill and Aleman, Rod chasing just behind. Then my chain came off at the surprise 7%, followed by BSIM loosing signal and what seemed to be putting me back on a different course!
