XT grouppo

By Sh8-monolovr

I have this group on both my 29er hard tail and 6 inch all mountain bikes. I love it it shifts great and is responsive. Not to mention it looks sexy. The gear ratios are good. The brakes are sweet beyond belife and are what you want if you like your bike to slow down and even stop as silly as that may be.
