The following front suspension and rear shock models are known to be incompatible with Quarq's ShockWiz.
For more about compatibility, check out the ShockWiz Compatibility Requirements article.
Cane Creek
Double Barrel Inline AIR (January 2017 to present):
The latest iteration of the Double Barrel Inline Air rear shock has a redesigned air can that features a 'parallel to the air can' inflation valve. The ShockWiz hose will contact the air can due to the small amount of clearance this design creates. ShockWiz CAN NOT be used with any Double Barrel Inline Shock that uses this parallel inflation valve.
Diaz Suspension Design
The Runt:
This air-spring add-on functions by creating 2 separate positive air chambers - one high-pressure chamber and one low-pressure chamber. During the compression of the fork, the compression ratio measured by ShockWiz will change. This creates a variable compression ratio making it incompatible with ShockWiz.
Formula
Neopos:
Formula Neopos is a variant of a traditional volume spacer that is added to existing air springs. These spacers compress during the suspension stroke, creating a variable positive air spring volume making them incompatible with ShockWiz.
Fox
Equalizer Rear Shock (Exclusively on Scott):
All versions of the Equalizer rear shock are NOT compatible with ShockWiz. This shock features multiple positive air chambers. Depending on the "Mode" that the shock is in one or both of the air chambers may be active, resulting in a variable compression ratio.
Dyad Rear Shock (Exclusively on Cannondale):
All versions of the Fox Dyad are NOT compatible with ShockWiz. This Shock features multiple positive air chambers. Depending on the "Mode" that the shock is in one or both of the air chambers may be active, giving it a variable compression ratio.
Nude TR Evol Rear Shock (Exclusively on Scott):
All versions of the Nude TR Evol shock are NOT compatible with ShockWiz. This shock features multiple positive air chambers and this creates a variable compression ratio.
Manitou
Dorado Air System:
All Manitou suspension forks that use the Dorado Air system join the negative and positive chambers of the air spring when a shock pump is installed. The ShockWiz hose acts no differently than a shock pump when installed.
MRD IRT (Infinite Rate Tune):
This air-spring add-on functions by separating the positive air spring into two separate chambers (. This creates a variable compression ratio in the positive air chamber measured by ShockWiz making it incompatible.
MRP
All MRP Suspension Forks from 2014 through 2016:
MRP Suspension forks manufactured during this time feature an air spring that fills through the negative air chamber. ShockWiz cannot function when attached to the negative air spring and is therefore not compatible with ANY MRP air spring that fills this way.
Ramp Control Cartridge:
This air-spring add-on functions by altering the volume of the positive air spring chamber during compression. This creates a variable compression ratio making it incompatible with ShockWiz.
Ohlins
RXF 34 & 36 Suspension fork:
The RXF 34 and RXF 36 suspension fork use an air-spring design that features two positive air-spring chambers. This creates a variable compression ratio in the air chamber measured by ShockWiz.
Not Compatible
DH Race Fork:
The DH Race Fork uses the same air-spring design as the RXF 34 & 36. This creates a variable compression ratio in the air chamber measured by ShockWiz.
RockShox
Suspension Forks with Dual Position Air (DPA) Springs:
Due to the way that the ROCKSHOX Dual Position Air spring functions it is not compatible with ShockWiz. When the ShockWiz is attached, it reads pressure from the negative air chamber making it incompatible.
Wren
Wren TwinAir Suspension Components:
Wren suspension forks that use a TwinAir design feature two positive air-spring chambers. This creates a variable compression ratio in the air chamber and cannot be measured by ShockWiz.
Other
DRCV (Dual Rate Control Valve) Suspension Products:
Exclusively on TREK Bikes - Suspension forks and rear shocks that feature the DRCV designation CAN NOT be used with ShockWiz. During a specific point in compression, a valve within the air spring is opened, which alters the air volume of the positive air spring and changes its compression ratio.
All Coil Sprung Forks/Shocks:
ShockWiz CAN NOT be used with ANY coil-sprung suspension fork or shock.
