The EXT Hydraulic Bottom-Out Control (HBC) is a position-sensitive damping system designed to improve end-stroke support and control.

It uses a secondary piston and inner tube near the bottom of the shock. As the suspension approaches the final 15% of travel, the secondary piston enters the tube, restricting oil flow through a calibrated circuit to create a controlled ramp-up at bottom-out.

By making the final part of the stroke more progressive, HBC allows for softer initial settings without sacrificing support at full compression. The result is improved traction, a more controlled feel, and consistent bottom-out resistance even on the roughest terrain.

Available on all EXT MTB shocks supplied by Ryder Imports New Zealand, the LOK 2.0 Pedal Platform system improves climbing efficiency while maintaining the traction and control EXT is known for.

Using a dedicated hydraulic circuit, LOK 2.0 reduces pedal bob and increases support during climbs and long pedal sections. In Open mode, the system is completely bypassed, allowing the shock to deliver maximum sensitivity and descending performance.

A built-in blow-off valve protects the shock if the platform is left engaged on rough terrain, while custom tuning options allow riders to tailor performance to their weight, riding style, and local trail conditions.

Ideal for trail, enduro, and e-MTB riders seeking the perfect balance of pedalling efficiency and downhill performance.

The EXT shock uses a low reservoir pressure system set at 55 PSI, designed to maintain consistent damping performance while reducing internal cavitation. This low-pressure design helps improve sensitivity and traction by allowing the shock to react more freely to small impacts, while still maintaining strong support under load.

The shock features a DLC (Diamond-Like Carbon) coated shaft, designed to reduce friction and increase durability under extreme riding conditions. This ultra-hard surface treatment improves smoothness through the stroke, enhances small-bump sensitivity, and provides long-term resistance to wear and corrosion.
