Wheel compatibility FAQ
What wheel sizes are compatible?
STAC Zeros can be adjusted for 650c-700c or 25.5"-29" wheels. Trainers come calibrated for a 700c (29") wheel. Adjust the height and calibration for other wheel sizes.
Are thru-axles supported?
Yes, but they require a thru-axle adaptor. Find one through the Robert Axle Project: robertaxleproject.com
Are disc brakes compatible?
Yes. Disc brake wheels generate slightly reduced resistance because the rims are built lighter. Double-check height alignment with the wheel rim, and use your bike's highest, fastest gear to maximize resistance.
Are MTB or CX bikes compatible?
Yes, with smooth or knobby tires less than 2" (50 mm). Make sure to check for steel pins; they're more common on MTB wheels.
Are there any requirements for compatibility with the wheel weights?
Wheel weights are compatible with most wheels, with a few exceptions.
