A completely unique system for Speedplay pedals to reduce aerodynamic drag and increase biomechanical efficiency by reducing the stack height by 3mm. For those riders searching for every watt saving solution possible, this is a must have. Currently used by World Cup winning Huub Wattbike Test Team.
Designed for use with a 3 bolt shoe. Our reduced depth stack plate replaces the standard adaptor plate. To do this the shoe needs to be drilled to suit a 4 bolt system.
We appreciate drilling your shoe's baseplate isn't for everyone so we have teamed up with custom shoe specialist Gallus Baffies as our approved installer. Once an order has been placed you will be supplied with the address to send your shoes to. Gallus Baffies will carry out the install for you. This is included in the listed price.
As a comparison of relevant shoe stack heights. Please note the stack is measured from the centre of the pedal spindle to the bottom surface of the shoe.
Look Keo - 17.1mm
Shimano SPD - 13.7mm
Speedplay Zero (3 bolt system) - 11.5mm
Speedplay Zero (WattShop system) - 8.5mm
