Tools & Maintenance

Although this was a good deal on the exact part I needed, I was converting from MS to XD, so ended up also needing a new axle end cap. Save yourself the shipping fees and get them together. Aside from that, perfect.
Oh - and be careful with the springs. You need your old ones and when they pop out they can be really hard to find.

Thunder mountain always has what i need at a great price!

Authentic Shimano at a reasonable price.

XTR works great and when it doesn't they take great care. Sometimes the extra cost is worth that warranty. Thunder took great care of me when I had some issues with my shifter.

Used this XT to replace the Deore cassette that shipped on my new mountain bike for the weight savings. I also replaced the Deore crankset with SLX (the XT is actually a few grams heavier than the SLX). It works great and love that the different Shimano product levels are all compatible.

Arrived promptly, fit like a glove on XTR M9100 crank

Very good

Bought the new TRP EVO PRO lever assemblies to upgrade my old brakes and having the bite adjustment and reach adjustment makes it's so easy to dial in the how quick your brakes bite and where you like the blade to be while riding.

Super easy to switch out to the new ones and only had to do a quick lever bleed on each one afterwards to dial things in.

If you already have TRPs and want to get a better feeling lever blade and way more adjustibility then these are the way to go!!!

Switched out my old TRP EVO levers for the new PRO ones and also ordered their new adapters for dropper lever and shifter lever. These new adapters integrate into the levers so much more nicely than the old levers.

Oh and Thunder Mountain is super fast about shipping things so everything showed up way faster than I expected!

Upgraded this with new xtr shifter from XT that came on the bike. Shifting is very crisp and effortless.

This is my 3rd pair of Deathgrips! They’re the best.

The best wheels I’ve had!

They are a total Game changer!!

Two day shipping and fast shipping

They always have what I need and have fast shipping. Thanks guys.
