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.

Inflates my gravel tires as advertised. Excellent customer service, fast shipping, happy customer, thank you!

Great price top quality you can not go wrong Thanks

Amazing little tool!

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

Theyre great

Good price and great customer service!

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.

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

Smooth hub and great wheel for trail riding!!

These are the best crank boots, use them on all my Shimano cranks.

Shimano quality as usual, 5 stars.
