Shimano Deore M4100 Series

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.
