Looked up other manufacturer designs and they weren't like this they have lips on them. So I figured this product would just put it lips on me. ### ⭐ Junk *by R***T on December 30, 2022* Idler pully has wrong bearings on it. If you tighten pully against bracket, pully does not turn. The pully MUST be tight, otherwise the belt skips. ### ⭐⭐⭐ It works great no pop from chain *by B*** on August 19, 2019* I like the product , I only wish it came with a little instruction and or a sprocket hub adapter . Since I received the belt and put on ,my bike has been down ! πŸ˜“ when I parked it because of broke chain and ordered belt drive because I was tired of hassle with chain , the clutch drive pulley is rather large and tight fit but works ,I can’t wait to get it all good again πŸ˜“ . The customer service for this outdoor power equipment was absolutely outstanding!
