If your skier skips - has a 'ratchet' sound and occasionally gives way, you need to IMMEDIATELY REPLACE one or both center DRIVE ROLLERS.
Drive Rollers internally wear down over time - normally, 5 ~ 10 years of sustained use.
Please contact NordicDanny - your Ski Machine Specialist at NordicFitnessTrack anytime -- 24 / 7.
