General Double Barrel FAQs

  • Do you make a Double Barrel to fit my bike?

    Most likely, but we need to know the year and model of your bike to ensure there is adequate clearance. Because the width of the Double Barrel's twin adjusters and large reservoir volume, there are bikes that it won't fit. Having said this, we make a shock for any bike worth owning, so we've heard some say if the Double Barrel won't fit your bike, it's time to get a new bike. Click here for our shock fit finder.

  • Can you valve a Double Barrel shock for me and my bike?

    The Double Barrel eliminates the need for "custom valving". The Double Barrel is so user adjustable that you (the rider) custom tune the shock yourself, to match your conditions, riding style, and trail/course. Instead of having to send the shock off for tuning, you just turn the external adjusters to dial in your unique settings. Because each adjuster is independent (for example: changing high speed compression will not affect anything besides high speed compression) the Double Barrel is remarkably intuitive to tune. A comprehensive instruction manual is included with each Double Barrel that explains how the adjusters work and how to get the most out of your shock.

  • Is a Double Barrel difficult to adjust?

    No. In fact it's quite simple. Since the Double Barrel is the only shock that offers 4-way independent adjustment with no air pressure to change, it's as easy as turning an external adjuster.

  • How do I get my shock back to factory settings?

    Pretty straightforward. See pages 5-6 of the Tuning Field Guide for instructions.

  • Why do you ship a shock at these particular factory settings?

    Every shock is shipped at the settings we use to verify the shock's function on the dyno. These settings can be used as a starting point, though really any settings could be used as a starting point! The intent is for the rider to tune it to work best for them. Use the Tuning Field Guide for getting started tuning your shock. 

  • Why doesn't my Double Barrel have spherical bearings?

    The Double Barrel comes with hardware to specifically fit your bike. Generally, for a bike with a spacer bushing requirement over 1" wide we use a DU type bushing. For bikes under 1" wide such as the common 22mm x 8mm spacing we can use spherical bearings in the shock's eyelet unless the bike frame manufacturer specifies otherwise.

  • How do I measure my shock length?

    Measure your current bike shock as installed, fully-extended (ideally with rear wheel off the ground), from each mounting bolt center-to-center.

  • What size DU bushings does my shock need?

    For the DBInline, the DU bushings are 15mm. Other Double Barrels - DBcoil, DBair, and DBair CS - are 14.7mm. Older DBcoils with a "C" in the serial number have 16mm. We have DU bushings available for all three. The same bushing assembly tool will install and remove all sizes.

  • What is the service interval on the Double Barrel damper?

    We recommend getting your shock serviced after 100 hours of use or annually.

  • The Shock Fit Finder says to call Cane Creek. Why?

    The Shock Fit Finder shows the broad range of bikes on which Double Barrels fit. But there's some on which we know our shocks won't fit because of clearance issues with our twin-tube design and large reservoir. There are others where we are still determining fitment. In those cases, to be sure give us a call at 800-234-2725. Who knows, you might be able to help us figure out a perfect match with your bike and a Double Barrel!

DBCoil FAQs

  • Will my current shock 9.5x3.00 (240x76) fit the 2012 Specialized Demo 8?

    The length is correct but the lower shock eyelet needs to change to fit the Demo 8 unique rear link. This repair is rather involved, and must be completed by one of our service centers. Some distributors currently carry Demo 8-II-specific Double Barrels. Contact your local bike shop for more information.

  • Why is the diameter of the DBcoil shaft smaller relative to other shocks?

    Because it can be! Most other shocks have a rebound adjuster contained in the shock shaft. This requires a larger diameter shaft because the inside is hollow. The Double Barrel's rebound adjusters are in the cylinder head so a smaller diameter solid shaft can be used. To get even more complicated, most other shocks rely on the oil displaced by the shaft as it enters the shock body to provide external damping adjustment. The shaft has to be made artificially large to provide even a minimal adjustment range. The Double Barrel is different. It does not rely on the oil displaced by the shaft to provide external damping adjustment so having a smaller diameter shaft doesn't reduce adjustability.

  • Will the DBcoil work with low leverage ratio bikes?

    Absolutely. Other than the need for lighter springs (Cane Creek specifies the correct spring rate based on your weight & bike), low leverage ratio bikes require lower damping values. Shocks "move" faster on lower leverage ratio bikes, so the damper force value at a given velocity must be lower than it would be for a higher leverage ratio bike. The Double Barrel's massive adjustment range allows these lower damping values to be achieved by simply turning the adjusters.

  • How about high leverage ratio bikes?

    Again, absolutely. High leverage ratio bikes can give some dampers fits because of the slow shaft movement and large damping value requirements. Not the Double Barrel. The adjustment range is so wide, it can easily be tuned for even the highest leverage ratio bikes.

  • Can I change air pressure on a DBcoil?

    There is no need. Take your shock pump out of your backpack (unless your fork needs it!). The DBcoil's sealed nitrogen charge is set at the factory and will not need adjusting

  • Do you sell titanium springs?

    We no longer sell titanium springs. One place they can be found is Renton Coil Spring Company.

  • What is the minimum required spring ID (inner diameter) for the Double Barrel?

    36.3mm (1.43")

  • When I pull up on the saddle of my Specialized Demo 8, it feels like my DBcoil tops out. What is this?

    The feeling you get when pulling up on the seat is a good thing. Because of the linkage and bearings on the Demo 8, coupled with the design of the DBcoil, there is almost no stiction in the linkage. If you have little or no pre-load on the spring and pull up on the seat, this will allow the rear wheel to drop freely to the end of the stroke and touch the top-out bumper – Think no resistance in the bearing pivots here, which is a good thing, as it's very supple and will provide plenty of traction. Now try adding 3-4 turns of pre-load to the spring and this feeling will then start to go away. This is because you now have bound energy in the spring extending the shock. We recommend at least 1-2 turns of pre-load on the spring.

DBAir FAQs

  • I am not getting full travel from my DBAir, what should I do?

    First, make sure SAG is properly set, from 25%-33% depending on your bike and preferences. Then, adjust High Speed Compression (HSC) - turn the adjuster out in half-turn increments.

    Our Tuning Field Guide is a good reference for all shock setup questions. Note that on the DBAir, the o-ring on the piston will not press against the piston head; the internal bottom-out bumper protects the air can with 3-5mm of piston distance.

    If you are still unsure, please call our Customer Service team at 800-234-2725 or info@canecreek.com.

  • What air pressure should I use?

    Your Double Barrel should be pressurized with a high quality shock pump. We offer a no-loss pump in our web store that does the job well. Sag can vary depending riding style. We recommend an air pressure that results in shock's O-ring being moved 25-35 percent away from the piston side when the rider sits on the bike in full gear. Start by putting in 20 pounds less air than rider weight in full gear. Measure sag and adjust pressure up or down, accordingly. See "Setting SAG" in the Tuning Field Guide for details.

  • Can I use oil to change the air volume in the air can like some other air shocks?

    No. Adding oil through the air valve will expose the internal seals to the oil added. This interferes with the moving parts and seals, and will eventually lead to failure. Volume reduction spacers can be purchased at our store.

  • What is the recommend air spring rebuild interval?

    We recommend servicing your air spring specific parts every 100 hours of riding or twice a year. This is an approximate guideline and will vary based on environment, riding style, etc. Damper service interval is approximately every 100 hours of riding; similar to the DBcoil.

     

  • Can I put a DBAir on my Specialized DEMO 8?

    At this time the only shock designed to fit the Specialized Demo 8 is our DBcoil shock.  Modifying a DBAir in any fashion is not recommended and will void the warranty.  

  • Why would I need an XV (extra volume) air can?

    XV or extra volume air cans are useful for a sub-class of bikes with a significantly progressive leverage ratio.

DBAir CS FAQs

DBInline FAQs

  • What air pressure should I use?

    Your Double Barrel should be pressurized with a high quality shock pump. We offer a no-loss pump in our web store that does the job well. Sag can vary depending riding style. We recommend an air pressure that results in shock's O-ring being moved 25-35 percent away from the piston side when the rider sits on the bike in full gear. Start by putting in the same air pressure as rider weight in full gear. Measure sag and adjust pressure up or down, accordingly. See "Setting SAG" in the Tuning Field Guide for details.

  • Can I use oil to change the air volume in the air can like some other air shocks?

    No. Adding oil through the air valve will expose the internal seals to the oil added. This interferes with the moving parts and seals, and will eventually lead to failure. Volume reduction spacers can be purchased at our store.

  • What is the recommended air spring rebuild interval?

    We recommend servicing your air spring specific parts every 100 hours of riding or twice a year. This is an approximate guideline and will vary based on environment, riding style, etc. Damper service interval is approximately every 100 hours of riding; similar to the DBcoil.

  • Is there an XV (extra volume) air can for the DBInline?

    Because of a design that uses a large air volume compared to the DBInline's smaller size, XV (extra volume) air cans aren't needed for this shock.
