You can’t never go wrong with Shimano product(SRAM folks be hating)
XT is top of the line when it comes to MTB/TB
Thunder mountain bikes staff makes the process of purchasing a product even better. I do appreciate everything Ian have done to get me set up.
And thank you for always stocking Shimano products and for always having a person on other end of the transaction!
Great prices, accurate descriptions and fast shipping.
As always Shimano delivers. XT components are still the best bang for the buck. Thunder Mountain Bikes had the best price out there for this particular part.
