Description
Replacement pulleys for Wahoo KICKR V4. There are two different versions of bearing system in the V4 KICKRs, each uses a slightly different pulley and it’s imperative that you use the right one!

The trainer uses a wave washer between the flywheel and the left hand bearing. The pulley has a 1mm deep counterbore as standard.
Spacer tube type
The trainer uses a spacer tube between the flywheel bearings for prolonged bearing and flywheel shaft life. There is a 0.5mm shim between the flywheel and left hand bearing NOT a wave washer! The pulley has a 2.5mm deep counterbore as standard.
