ABOUT SLIPPAGE PROBLEM
Minoura's Rim Drive System works off the wall of the rim, not the tire. This system allows use on a wide
variety of rims including disc brake rims. Slipping will happen when pedaling strongly or the resistance
on the mag unit is set high. This slippage is normal and to be expected.
If you experience slippage all the time you use the trainer, check the belt tension first by pushing down
the belt with your finger. The K-16 V-belt will be worn down after long term of use but most reason for
the slippage problem is caused by improper (too much or too less) tension adjustment.
To adjust the belt tension, loosen both upper and lower bolts which hold the pulley arm by an M5 hex
wrench, then pull the arm outward by your hand and tighten the bolts firmly again.
If the V-belt is completely worn down or damaged, replace it.
This work requieres high skill for disassembling and assembling the Mag unit. If you don’t have confi-
dence, please ask to the Minoura dealer where you purchased the trainer.
