These are fantastic! 3 years plus, 2000+ later and they are still going strong.

Been rocking these on my lacroix lonestar for the past three years. I’ve ridden well over 2000 miles and they are not even close to wearing down. If you’re in the market for a motor pulley that will last vs the stock aluminum ones get these. They are worth the money! I wish they made a 16T variant of these as I kind of miss the off the line torque but the stop speed is amazing.

These are amazing

I love these pinions. and the grub screws are a game changer, simple and needed. Great work Matt as always.

So quiet!!

These are basically silencers. My board went from being really loud with the Aluminum pinions to almost silent with these. So far I really like them.
