Holly Newton
Xt brake lever

Great price and fast shipping. I needed a replacement brake lever and Thunder Mountain had the best price. This particulate lever has a little catch on return. This is unnoticeable when riding but it is not something I’ve ever noticed on other Shimano levers.

Jack Gu

Deore XT BL-M8000 Disc Brake Lever

Nice strong brake

The brake quality and function are typical XT greatness. The bar clamp is different than the sain lever I replaced. Had a little shifter/seat post lever interference. No fault of the brake but worth noting.

Service and products in stock

Needed a replacement Shimano handlebar brake and TMB had what I needed in stock and shipped to me so fast! Thank you for the really quick turn around and great selection. Site was great to use and easy to checkout. Great shop because of great people, ride-on!

Deore XT BL-M8000 Brake Levers

Great price & fast shipping with Thunder Mtn Bikes. The levers are a perfect upgrade from the stock Shimano levers that come on most bikes nowadays.
