Minoura Urethane Roller Belt Replacement - Durable & Smooth Cycling Roller Belt for Indoor Bike Trainers - Perfect for Home Workouts & Spin Classes

Package arrived on time with minimal waste materials. Fit onto my 25 year old rollers with large-ish cylinders. Sits snugly in the drum grooves and drives the front drum without large oscillations between the nodes of the drums (which was what led to the premature demise of the previous drive belt). I’ve used it for a handful of spins (about 150 miles worth) and it has performed flawlessly for Z2, cool downs and intervals.
