T500 520 chain conversion
Posted: Wed Aug 23, 2023 3:58 pm
For the T500 cafe build, picked a fat ContiGo 120/90-18 tire on an Excel shouldered 2.5x18 rim, and a fat 530VX3 chain. Not quite enough clearance to properly line up the wheels.
It’s close, so a 520 conversion with offset sprockets should be ok.
530 & 520 chain widths:
