    Being a heavier rider I added the Cush to my rear

    Being a heavier rider I added the Cush to my rear tire and it seems to really help. Watch the install videos, because it helped a ton! Always love dealing with Thunder Mountain!

    Best stem in n the market.

    This is the third industry 9 stem a35 (50mm) that I have purchased in the last 3 years (for 3 Different builds). They are the best in my opinion and look good too!.

    Great addition to my girls bike. She sits more upright and feels like she has more control of the bike. The pink is just the added addition she loves

    So far so good

    So far so good. I like that I don’t have to be clipped in and they have plenty of shoe contact. I have only been out on them a couple of times but they seem worth it. Also big thanks to Thunder Mountain because they shipped these to me so quick!

    In stock and ready to go.

    We have been purchasing various parts from Thunder Mountain Bike for a few years now. They have always had parts in stock and ready to go. When we need the odd random item, this is one of the first places I check.
