What is the Hammerschmidt crank really capable of? We tested six Hammer enduro bikes together with downhill pro Marcus Klausmann.

So, how does the crank handle?" Why just the crank? After all, we have some very interesting enduro bikes in our luggage. But no matter where you go, the Hammerschmidt gear crank from SRAM takes centre stage. The bike around it is secondary. Our test field consists of six of these side issues: hand-picked Hammerschmidt enduro bikes between 2799 and 4800 euros, all fighting with the same weapons. Back to the crank. The X.9 trigger lever on the left-hand side of the handlebars is an old favourite. A short, defined push and the crank clicks. Much faster than with a front derailleur, under full load as well as when stationary. The reverse shifting logic of the gearbox is unusual: the large lever is used to access the light 1:1 mode and the small lever is used to activate the so-called overdrive with 1.63 times the gear ratio.
