The Clearance Clarence:
A simple laser-cut tool to check clearances for double and triple, road and MTB chainsets, made from 3mm stainless steel.
Note that this is only a guide, if clearances are going to be tight best to measure the actual chainset and bottom bracket you’ll be using.
Clearance Clarence – £15 
Hey,
£15 seems like a bargain for the Clearance Clarence.
Are you on lockdown or is it possible to swing by your shop and pick one up?
We can arrange a handover!
