Make your move to 1X and crush the steepest climbs on your trail bike with the EX cog.
Add much needed range to your existing 1x 10 speed drivetrain without breaking the bank. Shifts stay crisp thanks to e*thirteen speed shift technology and the EXA+ anodized aluminum resists flex under heavy power.
Pair this with a dual width Guidering M you are ready to go.
