Performance Redefined
Manufactured and hand assembled in-house by the legendary
suspension technicians at PUSH Industries, the new HC97 Compression System
replaces the stock compression assemblies found in the popular Rock Shox PIKE,
Lyrik forks equipped with Charger 2 and 2.1 dampers. What does this
mean for riders? Increased traction and small bump sensitivity with higher
levels of stability and control all while giving riders more external fine-tuning
control over their front suspension.

PUSH engineers focused on creating a far more useable
adjustment range for riders looking to get the most out of their front
suspension performance. With an updated 28 clicks of low-speed compression
adjustment externally, riders will no longer find themselves hunting for a
setting “in between” clicks. Utilizing the parabolic low speed needle design, borrowed from ELEVENSIX, riders have a precise and consistent change
between each click. Additionally, the high-speed compression adjustment of the
new HC97 Compression System features a fine thread adjuster barrel also offering
28 clicks of precise resolution over the damping curve range.
Shim-Less Design
Harshness has met its match! With traditional shimmed
compression valves, steel shims are bent upwards as fluid flows through the
valve. The more aggressive the impact, the more these shims need to bend in
order to allow the wheel to move through its travel. This shim bending is
progressive in nature resulting in an increase in damping force leading to
harshness on square edge impacts. Removing valving shims to help reduce
harshness at high speeds leads to an overall reduction in compression damping
and results in a decrease in low and mid speed control and performance.

The exclusive PUSH
“Shim-Less” Compression Valve design, also borrowed from the class leading ELEVENSIX
rear shock, eliminates this compromise. The progressive nature of shim bending is
replaced by using a precision machined sliding valve seat that can “dump” fluid
under the most aggressive square edge bumps. This resulting fluid flow allows
the wheel to compress more freely in aggressive terrain resulting in more
comfort and control through every stage of the fork travel.
Damping Synchronized
Low and high speed compression, low and high-speed rebound,
mid valves, shims, bleed ports, needles, bladders…how does this all work? Well,
MTB dampers are a complex animal and when you hit a bump, the damper
experiences a very complex series of events. Having all the internal systems
synchronized optimizes the damper’s ability to respond and therefore directly
relates to the fork’s suppleness, control, and comfort when the trail gets the
most aggressive. With the HC97 from PUSH, our engineers first focused on improving
the communication between the internal systems ensuring proper balance at all
suspension velocities. Imbalance in these velocities is referred to as
“Hysteresis” in suspension terms and relates to the “delay” in the damper’s
response when changing from the compression to the rebound stroke. The HC97
provides key improvements in this area resulting in better bump sensitivity and
cornering traction.
