Stage6 12mm-10mm bearing adapter

Stage6 small end bearing, adapter for 12mm to 10mm piston pin reduction. Made for owners of Stage6 crankshafts for 12mm piston pins who want to use a cylinder with 10mm piston pin without having to replace the entire crankshaft.

Note: it has a 17mm outer diameter which means that it is not compatible with all crankshafts; many have a 15mm or 16mm outer diameter. So make sure it will be compatible before ordering.

10x17x13mm.
