HAMMERSCHMIDT USE

HammerSchmidt has two front transmission gears: 1:1 and

Overdrive. In 1:1, everything in the mechanism is locked and

spinning together; one turn of the pedals equals one revolution

of the chainring. This is great for tackling steep climbs! In

Overdrive, one turn of the pedals equals approximately 1.6

revolutions of the chainring. This is great for hammering big

descents!

The shift from 1:1 to Overdrive can be made smoothly and

instantly using the proprietary HammerSchmidt X.0 or X.9

trigger shifters. Press the large shifter paddle to pull cable

and you’re in 1:1. Instantly! Press the small shifter paddle to

release cable and you’re in Overdrive. Instantly! With only two

shifting directions, you’ll never make a bad shift.

Remember, you can shift in any circumstance, no matter what

your chain tension is without having to plan ahead.

HammerSchmidt does not depend on pedaling; shift while

regrouping with your crew before the next climb, shift mid-

manual, even shift while coasting or pedaling backward. Shift

smoothly and instantly anytime, every time. Your days of front

shifting as you know it are over. HammerSchmidt!

Use only water and a mild soap to clean the HammerSchmidt unit.

Do NOT use a pressure washer. This will damage the seals and

allow dirt/debris to contaminate and potentially damage the

internals of the HammerSchmidt unit.

Periodically inspect all of the bolts of the HammerSchmidt unit and

crank arms for proper torque. See the service interval schedule at

Technical Service.

You should have a professional bicycle mechanic periodically

disassemble your HammerSchmidt unit to inspect the internals for

signs of wear or damage and to re-lubricate the mechanism.

Always inspect components for damage after any crash.
