Cane Creek DBcoil IL G2 Trunnion Rear Coil Shock
IL shocks feature class leading externally adjustable DB Twin Tube technology for the widest range of 4-way damping adjustability on the market.
Both AIR IL and Coil IL now feature a thicker inner damper tube for increased strength and a 17mm reduction in overall width on the valve body to increase fitment possibilities on tight frames. AIR IL features a 6mm reduction in the outer diameter of the Air spring to further increase the likelihood of fitment while increasing the max psi pressure up to 350psi (Up from 300psi). Coil IL features added detents on the preload collar allow more precise preload tuning.
Hand-assembled and individually dyno-tested in our Western North Carolina facility, IL shocks continue to provide a level of quality, performance and rider benefit that is unmatched.
INLINE SHOCKS TWIN-TUBE DESIGN
Setting the DBair & DBcoil IL apart from other inline shocks, oil circulates continuously through externally adjustable shock valves. Twin-tube shocks have two main chambers, a compression chamber, and a rebound chamber, separated by the adjustable valves. The main damping piston forces damping oil between the compression and rebound chambers via the externally adjustable damping valves.
Compared to other shocks in its class, Cane Creek inline shocks use significantly more oil in the damper; 40-50% more oil. On the trail, this routing of oil translates into less fade, more control, and greater consistency.
4-WAY ADJUSTMENT
The DB IL shocks offers an unparalleled range of adjustability through external adjusters that independently control each phase of damping without crossover effects. High and low speed compression, and high and low speed rebound are independtly adjusted.
Other inline shocks typically provide the user with a single rebound adjustment or rebound combined with limited pre-set low-speed compression. The easy tunability of DB IL shocks means a rider can make a quick trail-side change, increasing pop, plushness, or other features for personalized fine-tuning.
CLIMB SWITCH
When engaged, the low-speed damping is changed via a set of internal “climbing circuits.” We tune these circuits specifically for the demands of off-road climbing to achieve improved pedal efficiency with less chassis motion. Unlike other climbing platforms, our CS feature adjusts both low-speed compression and rebound.
All variants include the new integrated tool nested in our CS (Climb Switch) lever.
LinEair SPRING
The DBair IL features our LinEair Spring. Requiring a lower force to activate, the LinEair Spring provides the consistent feel of a coil shock from the initial stroke, full support during mid stroke and the added bonus of a progressive air spring curve when deep in the travel.
Features:
- Weight: 285 grams (weight varies by size, without spring)
- Damping: Twin-tube independent compression and rebound in two high-speed and two low-speed damping circuits
- Adjustments: 4-way independent adjustment: High speed compression Low speed compression High speed rebound Low speed rebound Climb Switch
- Shaft Material: Aluminum 7075
- Shaft Diameter: 8mm
- Frame Mounting Options: Standard or Trunnion
- Spring: VALT or Progressive VALT Springs
- Compatibility: COIL IL shocks are NOT compatible with Specialized Stumpjumper and Levo frames
Occasionally, without notice, manufacturers change product design and/or specifications.
Rear Shocks Sizing
It is not as simple as just bolting on any rear shock, there are some very important measurements to take into consideration.
Once the spring type (air or coil) has been decided, there two fundamental measurements needed.
Eye to eye: The total shock length. Measurement is made between the centres of each mounting hole/bolt in a straight line. This must match the new shock and is listed by the frame manufacturer in either mm or inches, often along with the stroke length. eye to eye is listed first and stroke length second. For example, 190mm x 50mm or 7.5” x 2.0“
Stroke length: The amount of travel the shock has (not the bike) can be seen by how much the telescopic part of the shock moves under full compression. Either the shaft itself can be measured or it can be worked out from the difference between the eye-to-eye length when fully extended, and fully compressed. Shown as the second number in the shock size by the manufacturer (eg 190mm x 50mm or 7.5” x 2.0”), this again should be the same as the original shock and as intended by the frame manufacturer to work with that particular linkage design.
Mounting hardware
Hardware includes the bushings and bolts that fit into the eyelets at either end of the shock, allowing it to be fitted to the frame. Although standards are starting to settle, the hardware will vary with each frame and shock combination. If replacements are needed there are dedicated suspension tuning specialists who can supply these parts.
Coil Shocks
Coil shocks can be tuned to your riding style by using a spring with the correct spring rate for your weight. The best spring for you will most likely be purchased separately, some riders will find they experiment with different springs to find their best set up.
Springs are rated by pounds (lbs) and this should be printed on the spring along with the travel length of the spring in inches. For example 400 lbs x 2.25”.
Coil springs are available in either steel or titanium, there is no noticeable performance difference between the two apart from the weight advantage of titanium.
Most people will experiment with spring rates to find the right spring for them, although a few turns of preload can be added when setting sag it is always best to find the correct spring rate for your weight, riding style, and frame.
Jargon Buster
Attack position – body position of the rider when riding into a technical section of trail, braced for any trail feature with weight balanced in the centre of the bike.
Compression – Controlling how the suspension moves through the available travel.
High-speed compression – How the suspension moves through the travel from High-speed hits not high-speed riding, for example rocks, roots, braking bumps, landing from jumps/drops etc.
Low-speed compression - How the suspension moves through the travel from low speed movement not low-speed riding, for example when under compression through a berm, going up a transition of a jump etc.
Linear – The strength required to compress the spring remains the same through the full movement.
Progressive – The strength required to compress the spring increases progressively through the full movement.
Metric – Referring to the eye-to-eye measurement of a shock in mm rather than inches.
Piggy-back – An extra part of the shock that comes out from the main body. This gives a larger oil volume for internal damping, offering better damping control and more consistent performance on extreme terrain. The frame design must have the space for this larger type of shock and will not fit all bikes.
Preload – How much the coil spring is compressed in its static state.
Rebound – how fast a shock returns to full extension.
Sag – how much travel is used under rider weight.
Shock pump – A high pressure air pump used to adjust air shocks, running at a much higher pressure than a normal inner tube/tyre pump.
Spring rate – The force needed to compress the shock.
Stroke length – the amount of travel the shock has, not the same as the amount of travel the bike has.
Trunnion – A trunnion mount shock has a larger body where one eyelet is housed in the body. This allows a longer stroke length in a shorter eye-to-eye.
Volume spacers – Internal plastic spacer that can be added inside an air shock to reduce internal air volume and so increasing the progression of the shock through its travel.
