DBAIR CS Twin Tube Technology
Exclusive Twin Tube Technology circulates oil continuously through the damping valving to achieve highly controllable, independent damping for both compression and rebound strokes. This unique design moves oil through externally adjustable valving instead of the main piston, allowing for superior tunability and eliminating the need for internal valving changes to achieve proper shock setup. The video below explains this concept in more detail.

4-Way Adjustment Low Speed Compression (LSC) LSC is used to manage traction and chassis stabilization. LSC adjustment eliminates pedal induced “bob”, influences small bump sensitivity, reduces brake dive and determines how the bike will react to weight changes. The DBAIR CS decouples LSC from HSC so the shock can address the aforementioned issues while still feeling plush and bottomless.
High Speed Compression (HSC) HSC is critical to absorbing energy from high impact forces, such as square edge hits and harsh landings. It also aids in bottom-out resistance. The DBAIR CS manages HSC through an adjustable poppet valve and full oil circuit flow path. The wide adjustment range allows for custom, rider-specific tuning. Low Speed Rebound (LSR) LSR works in concert with LSC to stabilize the chassis and manage traction. It is analogous to the single rebound adjuster on most other rear shocks. Rider-tuned LSR adjustment (combined with LSC) ensures maximum traction during technical climbs, high-speed chatter, off-camber corners and braking in stutter bumps. High Speed Rebound (HSR) An adjustment unique to the DBAIR CS, HSR control enables a bike to recover quickly from deep in suspension travel while allowing for controlled take-offs from jump faces. Independent control of HSR and LSR, eliminates bucking (a high shaft speed problem) while preventing the shock from packing up (a low shaft speed problem) by inducing quick recovery. Climb Switch (CS) CS is a proprietary climbing mode on DB shocks that changes the low speed damping via a set of internal “climbing circuits” when engaged. These circuits are tuned specifically for the demands of off-road climbing to achieve improved pedaling efficiency with less chasis motion.

Climbing switch technology
CS is the most innovative climbing feature available. This proprietary climbing feature (patent-pending) for Double Barrel shocks alters the entire low frequency dynamic response of the shock to specifically address the demands of ascending on a bicycle.

What is it?
CS is a selectable climbing mode on Double Barrel shocks that allows the rider to retain the advantages of a fully-suspended bike while climbing, without unwanted suspension motion. CS is not your conventional pedal-platform as it adjusts both LSC and LSR. By selectively tuning both compression and extension phases when climbing, the shock maintains better traction and control while enhancing pedaling efficiency through the shock?s entire travel.

Why is it better?
The strength of CS lies in the fact that it provides climbing-specific chassis damping in both compression and rebound. The result is better rear-end traction and connection with the trail while minimizing annoying pedal-induced bob. Simply put ? the rider is less fatigued and more comfortable. Traditional climbing ?platforms? only deal with one half of the climbing dynamics, and thus require the rider’s body to respond to the minimally damped rebound forces that are common during technical climbing.

How does it work?
The Climb Switch changes the low speed damping of Double Barrel shocks in one simple switch, to optimize suspension dynamics during climbing. It does this by turning on and off a set of internal ?climbing circuits? that are accessed when CS is engaged. Cane Creek tunes the ?climbing circuits? specifically for the demands of off-road climbing to achieve improved pedaling efficiently with less chassis motion. When the rider is ready to descend, with the flip of CS, the shock returns to the traditional low-speed circuits of the Double Barrel.

To best illustrate the advantage of CS, we created the animation below using real data from dyno plots of a shock with CS off and then with CS on.
How is it different?
The CS feature on DB shocks completely alters the low-speed damping character of the shock. That is, CS changes compression and rebound damping simultaneously to mitigate unwanted chassis motion while climbing without compromising the traction and control one expects from a modern suspension bike. Other shocks with climbing specific adjustments only alter the compression behavior of the shock with no impact on rebound. The Dyno Chart below illustrates the the action of the DBAIR with CS ON and CS OFF as compared to the competition. A damper generates force in opposition to velocity. As velocity increases, so too does the force generated by the damper.
Graph Overview
The horizontal axis of this graph shows shaft speed (velocity). Negative velocity indicates the shaft is moving into the shock (compression) while positive velocity is extending the shock (rebound). The vertical axis represents force. Positive force is the force generated to resist compression and conversely negative force is the force generated to resist shaft extension (rebound force). In a nutshell, the upper left quadrant is compression, the bottom right is rebound. As velocity increases (moves away from the middle) the force increases.

CS ON vs. CS OFF
The grey line is a graph of a shock with CS Off and is indicative of a typical Double Barrel damper at a mid-range setting. The orange line is the CS ON setting and is much steeper than the grey line. This indicates that for the same shaft speed, the CS ON setting develops more force. In other words, the CS ON setting is stiffer and resists movement more than the CS OFF setting and both compression and rebound are affected. For the rider, this translates into better traction and control at low speeds.

Traditional climbing Platforms
The red line is a competitor’s shock with the climb feature on and the blue line is the competitor’s climb feature off. Most notably, the rebound curve overlaps because there is no change in rebound damping. The compression curve is steeper because our competitors require more compression damping to make a bike feel efficient by limiting the suspension movement. The rider’s body is then required to respond to the minimally damped rebound forces and can experience less traction, less control and more fatigue.

CS stabilizes the suspension during both phases of the shock’s travel – so your full suspension bike can be a full suspension bike all the time.
