Upgrade a 720 chassis with the Serpent 803187 Brake Pulley Adaptor One-Way Set to refine braking feel and stability. The kit focuses on predictable behaviour when trail-braking and re-entering throttle.
The Serpent 803187 package includes a new 2-speed shaft, a one-way adaptor, a pulley adaptor fitted with a one-way bearing, an updated pulley, plus spacers and fixings. This arrangement permits the front and rear drivetrains to behave independently under braking, helping reduce unsettled rear-end action as rear tyres wear.
Because the centre pulley bearing disengages off-throttle, drivers can control rear traction without sacrificing turn-in accuracy. The result is steadier corner entry and improved mid-corner balance for consistent driving lines.
