Just wanted to post this in the Trek forum. I just received my 2013 Trek Superfly SL 100 Pro. As you know, it comes with Sram XX. I took off all the Sram XX parts and replaced with Shimano XTR.
If anyone out there has a 2013 Trek Superfly SL 100 and wants to upgrade to a Sram XX kit, let me know, I'll give you a great deal and everything is ready to fit on your frame. Only thing I kept was the Sid XX fok.
The parts ARE completely NEW and have NEVER been used al all.
