Set the circumference with Direto on a cycle-computer or a not-Elite app The circumference configuration on the external devices must be: Real circumference / ( subdivided per ) 12.1. Example: - Wheel circumference = 2095 mm, so 2095 / 12.1 = 173,14 - Must be set as 173 mm on the device Have more questions?

It seems that the wheel circumference should not be needed? Edoardo December 14, 2018 16:10 The speed sensor is not on the big pulley, and there is a multiplication between the big pulley and the little hub where the speed is read. Please set the circumference like this and it will work fine.
