Shimano M9250 Di2

I'm a big fan of One Up! Especially their dropper posts! It's my 2nd one. Thanks to Thunder Mountain for the GREAT price and fast shipping!!

So far so good. I like that I don’t have to be clipped in and they have plenty of shoe contact. I have only been out on them a couple of times but they seem worth it. Also big thanks to Thunder Mountain because they shipped these to me so quick!

We have been purchasing various parts from Thunder Mountain Bike for a few years now. They have always had parts in stock and ready to go. When we need the odd random item, this is one of the first places I check.

Quiet and powerful brakes. Rear brakes require a lot of work to route internally routed frames but caliper comes internally filled with oil so there’s less bubbles that need extraction. Overall a good upgrade from stock SRAM g2 brakes

Very happy with my new brakes. I upgraded from stock SRAM G2 R on my stumpjumper. Initially got a bad piston that wouldn’t retract fully causing rotor rub. Nate helped me file a warranty with Shimano and exchanged my caliper. Had to get more mineral oil to bleed caliper.

Brakes are quiet after after all and feel very powerful.

Been riding Eddy Currents ever since they came out and the new radial version is a marked improvement!

Grip and traction is amazing! I recommend adding an additional 3-5 psi versus your normal tire pressures on non-radials.

Bern super impressed with the grip these new radials provide and was abke to go with a 2.5 vs my normal 2.6 to gain better efficiency and less rolling resistance and the smaller width radial actually provides better traction.

I bought and did not need and return was fast and easy

Amazing Rims and price

Great price and fast delivery

Great price and fast delivery

Super light wheels, great beefy spokes, amazing hubs, instant engagement, flows and holds like crazy. Great sound to hubs too, but not so loud it takes focus off trail.

Great platform. Fantastic grip and feel. Pricey, but my favorite pedal.

Great price, and received very prompt responses to any and all questions i had

Fast shipping and you get free sticker which is SO rare nowdays

it came in perfect condition. The handlebars are like what I ordered.
