Page 7: Chapter 3: Basic Maintenance
Our indoor cycles are some of the quietest available because they use belt drives (GR5/6) and chain drives (GR3) and cantilever brake resistance. We use the highest grade bearings and chains/belts to minimize noise. However, since the resistance system itself is so quiet, you will occasionally hear other slight mechanical noises. - Page 8 DAILY Wipe down the indoor cycle after each use to remove sweat and moisture. Use soap and water, or a diluted non-abrasive domestic cleaner solution. Rinse to remove detergent residue and then dry off. Before each session, inspect for loose components such as pedals or cranks prior to commencing the next use.
