SRAM X0 Eagle AXS Transmission

Perfect fit, with the removal of 2 chain links! Gave me a little extra assist on those long climbs.

Hub fit perfectly, no issues whatsoever. Might have been nice to get some info about how much, what kind of grease to use but other than that, the product is great

Amazing!! 5 Stars

exceeded my expectations!! 5 stars👍

Ordered these to complete a Shigura set up and they were exactly what I needed. Worked well, great price and good delivery time. Hard to beat.

Order was in stock and shipped same day, can’t ask for better service than that.. Will definitely be ordering from Thunder Mountain again

Quick delivery. Correct product. Right price.

Great bike at a great price. The slack head angle will have the front end wavering all over on steep climbs and it feels like you need another gear if you are an XC person. Downhill however is like lightning. A new bike for the price of a used bike - this is a bargain.

The GX AXS transmission was explained to be not an evolution in drivetrains but revolution in technology. It is expensive so I held off...until curiosity got the best of me and the teeth on my 1st generation Eagle GX required a cassette repalcement so I made the purchase. 1. Shifting under full load in the middle of an extreme climb is a joy!! 2. Durability - the components of the deraileur are beefy - high confidence. In spite of the thin 12sp chain, it is also beefy 3. Installation - SRAM did an outstanding job to install, calibrate - set and forget - VERY well done. 4. Quiet - 'nuff said 5. battery on the deraileur overcomes battery anxiety by having a replacement in saddlebag to overcome horror stories of Shimano DI2 users getting stuck in one gear. No question I would buy again and now I'm thinking of AXS for my gravel bike!

Everything was groovy

great price on some excellent XT brakes. Shipping was SUPER FAST! I will be shopping again. Wish I had an LBS like Thunder Mountain.

USPS lost the shipment but Thunder Mountain Bikes took care of it. I received the reshipped levers and they are exactly what I needed at a great price. Thanks TMB

Cassette is good and a great experience. Purchased arrived on time.

Excellent customer service guiding me to the correct product for my bike. Electronics shifting has been awesome!

Great product. Fast shipping
