i-track is a patent pending rear suspension system for mountain bikes, which allows pedalling characteristics to be designed independently of any other design variables.

This means that other key factors such as wheel path and braking characteristics can be optimised to perform best in coasting/braking situations, while the pedalling characteristics can be optimised for pedalling situations.

At the heart of the i-track suspension system is an idler pulley which controls the upper chainline running between the front and rear sprockets. This idler is located on an ‘idler control mechanism’, which moves as a function of suspension travel.

As the suspension moves, the mechanism moves the idler along a predetermined path (or track, hence the name i-track).

This movement of the idler strategically controls the chainline, and hence controls the way pedalling forces are transmitted into the suspension system.The i-track suspension system also allows the pedalling characteristics to be tuned with greater flexibility than is possible with current suspension systems.

A common band-aid fix for poor suspension designs is to use excessive amounts of low speed compression damping to control the erratic behaviour that occurs when pedalling.
With i-track, having complete freedom to tune the pedalling characteristics, with great flexibility, provides a system that can be designed to eliminate ‘pedal-bob’. This means that low speed compression damping can be reduced to levels where it works best for its intended purpose. Less low speed compression damping means more sensitivity, more traction, and more control.

i-track suspension can be applied to all genres of full suspension mountain bikes, but is most beneficial to long travel suspension bikes such as downhill bikes and all-mountain bikes.

i-track suspension can be configured in many different ways, allowing bike manufacturers to combine this new technology with an existing design philosophy.

When properly applied, the i-track suspension system results in a bike that performs better in every situation.
