The TwinPegs™ idea is quite simply to add an additional footpeg behind the original footpeg, placed so close to the original footpeg that the riders boot will cover both. It does not affect the operation of the gear/rear brake levers, and the additional footpeg will have the same fold-away safety functionality as the original one.
The additional footpeg gives the rider firm heel support, which enables the rider to use the leg muscles to stabilise the body, rather than relying fully on support from the upper body. Thus reducing “arm pump” and general fatigue. The pivoting of the boot around the original single footpeg, is moved to the ankle joint.
