Great Product; Had to Grind Derailleur to Fit
Torque arm works great to manage the torque of welded clutch regen with my Bafang G62! However on my bike frame Mongoose Dolomite, the clamping block and torque arm did not clear my rear derailleur. It was very close, though. My solution was to grind several MM of material off my inexpensive rear derailleur. No Big Deal with a 15$ Shimano Acera... But of course, If I had a more expensive derailleur- grinding it might not be a great solution. Be sure to test fit everything and get the angle right before you hammer the splined pieces together! When assembled, that part is not easy to disassemble. Follow the instructions and watch the videos bcause its Important to install correctly!! Thanks Grin Tech

Clamping block is too large
the base for hose clamps is nice but the clamping block is too thick and too large, and doesn't work with the suspension fork I'm using. The block interferes with the tube part of the suspension and there will not be much thread left on the axle, even if only a single washer is used.
