    I9 Hydra 6b Bearing Tool Kit

    Very nicely machined, high quality, albeit a tad expensive, drifts. Plus, the colors look pretty. Need these to do the job right.

    I have the eagle 90 transmission with 30t chainring and now it has some protection thanks to thunder mountain bikes. The product works perfectly, easy install and back on the trail. Thanks thunder mountain bikes.

    Great Hub

    Needed a burly rear wheel to convert Ebike to mullet. Love hydra hubs though that engagement is useless with Ebike. The buzz is a bonus

    xt di2 8250

    This upgrade is amazing. Everything you need to go wireless. Easy set up and precise shifting, smooth and quick. Doubt if i'll ever go back to cable/housing.

    Great price and fast shipping

    Thunder Mountain Bikes is my go place for on-line purchases. They always have what I need at great prices and extremely fast shipping. If Thunder Mountain and “Shop X” have the same price, I always choose Thunder Mountain for their fast shipping plus everyone that works there are great people
