Lack of belt tension can lead to tooth jump or “skipping”, when the teeth of the belt slide
over the teeth of the rear sprocket. Too much tension can damage the bearings within the
rear hub, can cause the system to drag, and can increase the wear of your drive system.
Tensioning procedures vary depending on the bike. Common types of tensioning systems
include sliding or pivoting dropouts and eccentric bottom brackets.
Hang the main tower on the belt. Put the ruler on the two sprockets.
Check the tension: Red means increase the tension. Yellow means decrease the tension. Green means tension is good. Correct alignment of the belt has to be maintained as you adjust tension. The tension may vary a little along the belt, so you should repeat this procedure several times. Rotate the cranks a quarter turn after each measurement and measure again.
