Exactly what I needed to get my Rail onto Transmission! Loved the option to pick up the cheaper open box version.

I was careful and moved all my pawls and springs over, but if you’re not the most careful or want peace of mind, pick those up too! (And the end cap too, as you’ll need that no matter what.)

Well-finished and lightweight, just be careful not to scratch or dent them, as that will ruin them.

Good quality, lightweight.

Great price, fast shipping and a great product. Form and function is perfect!

Works perfect taking my 2023 SRAM 3 bolt DM Carbon XO DUB cranks (non wide) 52mm chainline out to 55mm DUB Transmission chainline my new bike was setup for. ( I replaced the heavier 2027 XO aluminum Transmission 8 bolt cranks) It spaces perfect and it also runs the T Type chain smoothly and quiet with great retention. Love it. 0 mm offset.

Great product, even better price, even better service. Great place will buy from again.

All taken care of and put back together. Thanks for the help Thunder Mountain.

Excellent price, I will definitely buy here again

Fast shipping, no issues what so ever. Wheels were packaged well and clearly brand new. Very satisfied with my purchase.

I just replaced my XX1 gold chain with another from Thunder Mountain. I clean and lube it every ride. It takes 2 minutes. My new chain measures 1466mm after sizing for my Scott Spark RC World Cup. My 2 year old chain measures 1467mm. One millimeter stretch in 2 years and 6500 miles of often wet Florida trails. Great chain.

If you are still using Presta valves after you have seen the Clik valves work, You..are...wrong.

I installed these 4-piston brake pads on my Teverun Fighter 11 Plus electric hyperscooter, and I couldn't be more impressed! The braking performance is absolutely phenomenal. Excellent stopping power, fantastic responsiveness, and a solid, confidence-inspiring feel when applying the brakes.

Awesome! Super nice and helpful, ordered new brakes for me and replaced them all in about a week.

I’m From out of town and needed a repair done for my mountain bike which was essential. I stopped in and these guys got on it right away, fixed it thoroughly and professionally. They were also a wealth of information for the local mountain biking. I highly recommend.
