Cranksets

The Runt Cartridge works exactly as described! It's an amazingly well priced upgrade for my Fox 36 Factory fork and I'm really enjoying the progressive feel that's leagues better and a far more precise approach than Fox's stock plastic spacers.

good fit, true to size and Thunder Mountain Bikes customer service excellent!!

Off the start, I would say 9 out of 10 on the way this item looks if you’re trying to go with that Kashima gold match this is perfect also extremely fast shipment would highly recommend ordering items from here.

The part I ordered arrived very quickly. Stoked out of my mind!

Nice sale price on this helmet, fast shipping

I had been using thunder Mountain bikes for different things over the years, but finally purchased a demo bike from them this summer. They were amazing about teaching me everything about it and then giving refresher lessons anytime I stop in. They just did an incredible tuneup that was under warranty, but they didn’t just do the basics they reviewed the bike from tip to tail and made sure everything was in good working order. Once again, I learned even more about my bike when dropping it off and picking it up. I would recommend these guys to.

Excellent service and friendly staff.

Great place to buy from smooth as silk. Highly recommended

The XX group set is probably the best transmission tier you can legitimately ride hard, and it works well. Smooth shifting, light but powerful cranks, and quiet. By comparison though, it’s still noticeably heavier than other wireless drivetrains and comes at a $erious premium. If weight isn’t really your primary concern the GX derailleur and cassette are more rugged and might shift better (personal experience), but as a whole package the XX still takes the cake.

Love that TM always has the small parts I need and ships super super fast to get me back on the trails so J dont miss any weekend rides

Rented e-mountain bikes, top of the line Ibis. Reasonable pricing, great service, perfect recommendations for trails. Excellent place!

Right product, right price. Shipped quickly.

Great product—better clipping in from any angle. Worth every penny.

I tried to find a generic kit that worked with my Motives but it’s a headache. This is just the recommended, right kit to use. Looks well built.
