Ordered the deraileur through Thunder Mountain Bikes. The product was exactly what I needed. Very easy process and fast delivery. The website has a lot to offer and they sell quality products. They are now one of my go to for shopping.
I purchased this derailer from thunder mountain. It fit perfect and the shipping was fast. Also like the cool sticker that came with my order.
Awesome derailleur at a good price. Thanks Thunder Mountain!!!
The Shimano SLX M7100 rear derailleur works just as well as the XT I currently have on my Ibis Ripmo V2, which surprised me!
Order received expeditiously, and exactly what I needed.
