XT replacement lever blade

Not compatible with SLX 7100 brake levers as hoped and unable to return since attempted install of blade

Leslie Chow
just what I needed

broke my brake lever blade and was so happy to find this rather than have to get the whole brake lever assembly (which is unavailable for 12 months anyways, yay supply chain..) customer service was great and was able to expedite shipping to make some scheduled rides. thx thunder mountain bikes!

Brad Lewis
Under promise, over deliver

The parts are exactly what I ordered, but the original turn around time was significantly longer on the shipping days because of the holiday weekend. Everything arrived 4 days earlier than expected. Very happy with the purchase and experience.

Adis Kovac
Perfect fit

It came only a couple days after ordering. Great experience and will be buy again from Thunder

Perfect fit

I have the Shimano XT M8120 levers & broke the rear one recently. Thankfully it wasn't the left side since (as of 6/6/22) they're out of stock! I used YouTube for instructions & this was not that difficult to install. I'm not a mechanic by any means.
