SRAM GX Eagle Series

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

Excellent product. Also Thunder mountain bikes were extremely helpful.

Thank you

Great bars, great fit and finish.

Code RSC lever arrived quick. Installed and upgraded from a Code RS lever. Better feeling and more springy return with the RSC lever.

These really do calm down trail buzz and makes my 70 year old arms able to hold on for long rides.

These chains are your dad.
