Great price and quality
Needed a quick replacement for a customer. Nice quality and good fit and easy adjustment. Only been on for a month, so I cant speak of durability as of yet.

Please inspect the product before shipping.
The product was easy to install, but when it arrived, one part was missing. Since I was in a hurry to repair my bicycle, I didn't report it. This is just an observation: please check the product to make sure it doesn't have any missing parts.

It's a cheap Shimano - just what I needed and OEM
Excellent, a new Shimano RD-TY21B - an exact duplicate of the mangled one I am replacing on a Jasion CB1 ebike I rescued from a guy on Facebook Marketplace. Very happy to have it cheaper even than my local bike shop and almost as fast to have it in hand.
