The �Puck� is an optical sensor which does NOT mount on the bike. Instead it sits on the floor beneath the pedal to sense pedal rotation which is communicated to the Handlebar Controller by cable. The cadence signal supports the display of both Cadence AND SpinScan�. The
sensor is rugged, sweat-proof and very easy to use. It eliminates the time required to attach and detach the standard cadence sensor from the bike.
The cost for the �Puck� as part of a new CompuTrainer is $149.95. Previously purchased CompuTrainers are "Puck ready" if the existing Handlebar Controller is Rev. 41.62 (purchased after approximately June 2012), Prior to that Rev. number, the Handlebar Controller must be rebuilt at a cost of $99.95. The Handlebar Controller would be sent to our factory for the rebuild using the following form including a note that it is for a Puck upgrade.
