Exactly what I needed

No offence, I never heard of this site until I broke my brake lever in a crash and this was the only place I found it in stock. It shipped quickly and was exactly as advertised. Most people are probably familiar with this lever already but its a great lever. If you are upgrading from something lower I would go straight to the XT but the SLX is great as well.
I couldn't be happier with my buying experience with Thunder Mountain Bikes and will be sure to check their site for future needs.

Of course the lever was great, it was shimano how can you go wrong.
What did impress me was the great service I got from thunder mountain.
Before I ordered I had a question so I called and spoke to one of your mechanic/bike riders Who was very knowledgeable and answered my questions spot on. Quick shipping with no hassle. 5 stars... thanks, you got me back on the trail..

Diego Yepez

Came quick, fixed the bike with the part. Much appreciated

Great Bike Shop

SLX lever is best bang for the buck. No need to go to XT or XTR unless you just like the bling but they won't stop you any better. As advertised and fast shipping. I added the hot sauce to get the free shipping. Delicious.

Ryan Rocks!

I called to inquire about a MTB brake lever. I was lucky to get Ryan who knows A LOT about bikes! He guided me to a less expensive lever, that was a better match for my situation. I learned a lot, they shipped the lever immediately, it arrived super fast, I installed it and rode the next day! Excellent experience. I will be checking with TM for any and all bike part needs I have in the future. Thanks again, Ryan.
