Utilizing a 14-Tooth / 18-Tooth Narrow/Wide pulley wheel combination, the EVO 1X 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 1X System. Due the environment that these Systems are used in, all E1X Systems will ship with pre-greased bearings from our HQ.
Every EVO Speed System is designed, tested, and hand built in Pawnee, Illinois USA.
