XTR chain

Life changing experience for those seeking the ultimate in 12 speed chains. No really XTR chains are excellent in durability and shifting performance. Bought two as these things are a wear item and do need replaced but do last longer than some other less expensive ones.

12 speed XTR chains on sale?

Oil slick chains are vain, XTR chains are subdued and reliable. You can have something pretty, or something that works every time. Prove me wrong. In stock and on sale, Thunder Mountain for the win!

Great service and solid product

Thunder Mountain seems to have a better inventory for components than most shops and does not mark up the prices. Shipping is prompt and the systems provide great order/shipping status.

Excellent chain

So light, very quite an stiff. So happy I hope it last more than XT
