Does anyone know the correct bottom bracket length for Stronglight 49d cranks running a single chainring/fixed gear set up on a road/track frame?
I currently have a TA 314 axle fitted which was correct for a set of TA pro 5 viz ('pista') cranks but I have broken these.
As this is the 2nd set of TA cranks I have snapped (the non drive side broke at where it fits to the BB axle this time with no warning) I am a bit wary of them , so would like to move to a set of 49ds which will after all be more period correct for the frame.
