about
At the heart of i-track, is a dynamic idler pulley that engages with the power transmitting segment of the chain.
This idler pulley is attached to a member of the suspension linkage, so that it moves relative to the bottom bracket and the rear axle, as the suspension is compressed.
When using this technology, a suspension designer is able to strategically control the dynamic movement of the idler pulley relative to the other drivetrain elements (front chainring and rear cassette), to achieve their desired targets for chain growth or shrinkage. This provides independent control of the anti-squat characteristic, allowing it to be tuned independently of axle path and other kinematic properties.
