12 tooth front sprocket

By: on 24 July 2025

I bought through ebay but I wish that I had come to you directly. I'm grateful that you listed the correct information for your sprocket as some ebay sellers are lazy and have no idea how to communicate. your sprocket matched and did the job perfectly , thank you.
