I have a mag trainer attached to my set of rollers. the trainer has adjustable resistance and a remote. I do not know the make of the mag unit.

well when my speed ramps up or I set the resistance high I get an awful squealing noise from the trainer. Needless to say the noise makes me slow my speed or lower the resistance but this does not help me get the best workout.

Do I need to get a better trainer or is there a fix for this?
check the band (if it uses one)jw25

If the unit uses a rubber band to transfer motion from the rollers, that's the likely source of the squeal. You probably have some oil on the pulleys or band, so clean them both thoroughly, and the sound should go away.
If it's a direct connection, look at the rollers. If the rears have tire deposits on them, and your tire looks shredded at all, you'll want to make sure they're inflated to optimum psi, and also clean the rollers.
If they're shiny, it's probably something inside the mag unit, and your guess is as good as mine.

I've got a mag trainer, and I've found it to have a harmonic resonance around 20 mph (rear-wheel computer). No matter the resistance, it'll hum at 19-20 mph, but quiet down above or below. It's not a squeal, though.
Good luck.
Maybe the bearings are shot. nmeschelon

Sure it's not tire slippage?cory

My trainer's sort of grumbly, but the only time it squeals is when the tire slips on the little spindle. Underinflation, crud on the tires or my dog drooling on the thing (he likes to sleep with his head pillowed on it) have been causes in the past. You might check inflation pressure and clean the roller and tire.

thank you all I found last night that the tension on the belt was to loose. Tightened it up and now no noise.
