Hey, What is the difference between a M14 and a M15 crank bolt because on Tartybikes they have Echo Sl crankbolts in M15 size only and I am wondering if they would fit my ZHI Isis bottom bracket.
Somebody said on a previous topic that Dan-Ko had spent some money which he had made to buy an Audi R8 And since somebody said Dan + China, It just sprung into my mind.
