High-Pivot

High-Pivot Rear Linkage

Overview

High pivot bikes typically use a single pivot design, but the pivot point is placed much higher than normal. This would result in unacceptably high levels of pedal-kickback if it wasn’t for the use of an idler pulley, which routes the chain line up past the pivot point.

The advantage of this design is two-fold. First, it provides a rearward axle-path. This in itself can help the rear wheel to deal with square-edge hits and contributes to the overall pedaling efficiency of the bike. Second, because the chain passes right by the pivot point, there is next to no pedal kickback. This further improves suspension sensitivity.

The disadvantages of high pivot designs include increased drivetrain drag and maintenance thanks to the idler pulley, high levels of anti-rise due to the high pivot point, and a rear-centre length which increases as the bike sits into its travel — this can have some odd handling characteristics.
