The slat belt in all Peloton Treads has some degree of slack or sag that can be seen from underneath the Tread's deck. The Peloton Tread is engineered with extra slack to allow for a smooth, fluid interaction between the slats, internal belts and guide bearings. Some variation in belt slack between units is typical and does not indicate a problem with the Tread. In some cases, if a Tread is on high pile carpeting, the slat belt may appear to drag on the carpet itself, but should not cause an issue when in operation. If the slat belt drops low enough that it makes contact with the surface of the floor, please contact our Support Team so that they may help resolve the issue.
