After many years of suspension analysis i came to the conclusion that in order to have zero pedal feedback with high amounts of antisquat and active braking i needed to ditch the chain.

Aim of the design

First proto will be an AM design
-use a rohloff hub mounted above the BB driven by the cranks via chain/sprocket.
-Send power to the rear via telescoping alu. shaft
-All of this mated to a 4bar linkage.

This will be a rolling labortary to test my theory,weight will be a crucial factor

Right now im in the stage of calculating and configuring the linkage to get the right amount of anti-squat with shaft drive.

One thing i noticed is the high amount of anti-squat when using shaft drive!(you take out the chainline in the equation)



All in good fun
