Maybe not the best place to ask but I have these on both my bikes so I’m probably gonna die soon anyway. What’s the right bottom bracket length to use with these? Some sites say to use a 110mm and some say to use a 107mm. I’m guessing that the length has changed over the years as on my bike with the older (safer?) primatos I’ve got a 110mm campag bottom bracket and the chain lines bang on. I’m looking to put a new bb in on my other bike with the newer black primatos on as there’s a creaking noise seemingly coming from the bb that came with the cranks (second hand, can’t see marking on the shell to denote size) and the chain line on this frame seems a little off. If the creaking persists with a new bb I’m just gonna assume death is knocking on the door and my cranks are about to give way.
