- Can someone please explain BCD?
As above really, am wanting to run a set of Rival cranks that at the moment have a 53/39 set up on 130BCD
But i am wanting to if possible use the cranks on my next cross bike build but run a 46/36 set up 110BCD
Can i do this? and what is BCD? is it the gap between the bolts?!Posted 4 years agoSuperficialMember
It’s not distance between bolts, it’s the diameter of the holes.
I’m not sure if you’re wrong or you’ve just worded that very badly.
It’s the diameter of the bolt circle. For a 4-arm crank, that’s also the (centre-to-centre) distance from one bolt to the opposite one.Posted 4 years agoMacavityMember
They do exist, but not always for chain rings.Posted 4 years ago
