Adventure System - Shimano XT/XTR 12sp

Utilizing a 14-Tooth / 18-Tooth Narrow/Wide pulley wheel combination, our Adventure System is unmatched by any competitor on the market when it comes to strength, durability, and performance!  Reducing drivetrain friction does not have to come with a trade-off of decreased durability, decreased shifting performance, or even taking an aesthetic step backwards (current offerings on the market).  SLF Motion Oversize Systems use cages produced from "Made In The USA" 100% real carbon fiber (unlike competing brands' nylon plastic "composite" cages) along with unique coated bearings for added durability and performance.  Improve your current stock drivetrain or even your current competing Oversize System with the installation of an SLF Motion Adventure System.  Every System is designed, tested, and hand built in Pawnee, Illinois USA.
