Take the KICKR indoor riding experience to the next level by adding physical grade changes to your ride using the KICKR CLIMB. Preparing yourself to take on the toughest challenges and tallest mountains. The world isn't flat; now, neither is your ride!
KICKR CLIMB quickly raises and lowers your bike to match ascents of up to 20% and descents of -10% when paired with the new KICKR or new SNAP. Climbing workouts and virtual courses are now more realistic than ever as KICKR CLIMB recreates the grade changes in real time.
KICKR CLIMB physically adjusts your bike position to mimic real roads and mountain climbing. This allows you to naturally change position on the bike, engage climbing muscles, and improve pedalling technique indoors to become more efficient and powerful climber outdoors.
Connect to the most popular online training platforms to create a truly immersive ride experience. Whether riding a virtual course or performing a structured workout, KICKR CLIMB blends physical grade changes with resistance changes to take your indoor ride to the next level.
KICKR CLIMB was designed jointly with the new KICKR and new KICKR SNAP Smart Trainers to deliver the best possible riding experience. This connection enables the Wahoo Smart Trainers to control the KICKR CLIMB. You can also use the KICKR CLIMB's remote to quickly pair to your 2017-model KICKR or 2017-model KICKR SNAP.

CLIMB Modes
Unlock Mode allows the CLIMB to react to grade changes from external sources such as Zwift or TrainerRoad, or from your ELEMNT or ELEMNT BOLT GPS bike computer. Lock Mode ensures the KICKR CLIMB will only respond to commands received from the remote.

Remote Control
KICKR CLIMB's remote attaches to your handlebars so you can adjust the grade manually with a simple press of a button. When not in use, the remote conveniently stores away in the top of the KICKR CLIMB.

Trainer Compatibility
The KICKR CLIMB works exclusively with the 2017-model KICKR (part code WFBKTR117), as well as 2017-model SNAP (part code WFBKTR2).

3rd Party Compatibility
When paired to a 2017-model KICKR or 2017-model KICKR SNAP, the KICKR CLIMB can match grade changes from select training platforms including Zwift and TrainerRoad.

ELEMNT Compatibility
Connect an ELEMNT or ELEMNT BOLT to your KICKR and KICKR CLIMB system to relive the ascents and descents from your favourite rides or routes while training indoors.

Bicycle Compatibility
In addition to standard quick release hubs, KICKR CLIMB also supports 12x100, 15x100, and 15x110 thru axle hubs.
