SLF MOTION EVO SPEED SYSTEM - Shimano for 11 speeds
Utilizing a 14-Tooth / 18-Tooth pulley wheel combination, the EVO Speed 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). Improve your current stock drivetrain or even your current competing Oversize System with the installation of an EVO Speed System. Every EVO Speed System is designed, tested, and hand built in Pawnee, Illinois USA.
