Wahoo Fitness KICKR CORE 2 Riser Feet

Overview

This is a series of replacement feet for the Wahoo Fitness KICKR CORE 2 Smart Trainer that raise it up higher than stock.

The axle of the KICKR CORE 2 is around 332mm above the ground. This is about the same height a a 700c x 23mm. If your front wheel or tire is larger than that, you may end up with the front wheel higher than the rear, which messes up your bike fit and makes the saddle uncomfortable. For example, with 700c x 32mm road tires I needed to raise the trainer 14mm to make the axles level and have it feel normal.

Supplied are a series of different height feet (+5mm to +50mm in 5mm steps) to make your bike level. These secure with the same screw as the stock feet, and labels inside of each foot note the lift above stock and let you keep track of them if you're printed different ones for different bikes.

What size do I need?

To find the size you need, you have three options:

1. Measure how far the front and rear axles of your bike are off the floor, and the difference is the height you need. (For example, if your front axle is 344mm off the ground and rear is 332mm, you need a +12mm riser, so choose either +10mm or +15mm, or export a +12mm from Fusion.)

2. Measure how far the center of the front axle is off the floor, and the difference between that and 332mm is the height of riser you need.

3. Use a ruler and a long level to measure how far the rear wheel is above the front, then choose the best fit or export a new model from Fusion. This method may be best if your floor isn't level.

How To Install

These replace the stock rubber feet which are held in place with a small screw (use a 3mm hex tool), accessible from the underside of the legs. Remove the screw and they slide right off.

More Details

Included is a parametric Autodesk Fusion model that'll allow you to make your own custom height feet. Change the parameter liftAdditional and everything else will adjust automatically.

Also included is project file from Bambu Studio showing the print settings I used, with the most important being 0.2mm layer height, 6 walls, and 25% gyroid infill.

The riser feet shown here on my trainer add 14mm height to the rear of the bike and were printed Overture PETG in Black at 50mm/sec with all fans off in a Bambu Lab P1S. Yes, this is slow, but it ensured good layer adhesion and a nice finish. (Other plastics, and much faster, would probably print and hold up fine as well. Let me know what worked for you.)
