Groupsets

The Crankset was delivered promptly and was exactly as described on the website. it's been working perfectly fine on my Canyon Dude with the other SRAM Equipment I picked up to upgrade the entire bike to a SRAM Electronic Drivetrain.

Well designed
Fast shipping

Nice, fit perfectly. Just they would last on my ebike.

Thunder Mountain always keeps my bike rolling. Thanks again, Kevin.

Very timely delivered. Guard seems to be guarding alright.

I have them on the front and rear and they are great. I like them on my local rooty trails and are just at home riding in Pisgah.

Fast shipping

I have had some issues with technical climbs, was told my free hub was part of my issue. Didn’t have money for a wheel set up grade, but this new ibis free hub for 69$ was a great compromise. Install was straight forward, thanks to many YouTube videos. I noticed a big difference immediately.
I buy from thunder mountain because it is not a variable,I can count on them.

Nice upgrade

Wanted to go up to 203 on the rotors - that was the right choice - and these were the right choice. So easy. Should have done it sooner.

Definitely will buy again. Thanks!

Helmet looks great and fits well.

Shipped very quickly and came in perfect condition, ready to easily install!
