My life gear advantage spin bike needs adjustment or repair parts since on the downward stroke of the peddles the arms seem to catch at the bottom of the stroke. I can't find a repair manual to see if I need the flywheel center bearing and "drawn cup roller" or if the problem is in the crank bearings or simply a tension adjustment on the grooved belt. Thanks. Jim
This bike looks to be of the Lemond Revmaster series.
first, dial the resistance knob back until the leather break pad is no longer touching the flywheel. Get down on the floor and postion yourself between the flywheel and pedal cranks. Slowly turn the cranks arms and listen and feel for a roughness in the bike.
This has bike has bearings and a belt. It should not make any noise.
Now with the right pedal at a 2:00 position tighten the resistance knob down all the way so the flywheel will not turn. Then get on and push very hard on the right pedal. If the belt is loose, the pedal will move. Austin Fitness Rentals Rent Commercial grade Fitness Equipment in... ">
Testimonial: "There is a slight bearing noise but I have replaced both outer bearings in the fly wheel. Your solution has definitely eliminated the majority of the problem. I feel the belt is not original since the set screw which increases tension is not long enough to apply the tension needed to stop the petal. I put a longer one in and it seems to allow me to stop the belt slippage."

No because your arms are stationary on the handle bars thewhole time.
