“Tested: 2014 Cane Creek DBair CS Rear Shock”

  • MSRP: $695 USD

How Does It Work?

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.

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 low speed compression and low speed rebound at the same time.

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 activating a set of internal ‘climbing circuits’ that are accessed when CS is engaged. Cane Creek tunes these "climbing circuits" specifically for the demands of off-road climbing to achieve improved pedaling efficiently with less unwarranted chassis movement while retaining an active suspension platform.

Initial Impressions

Having already spent a day testing the DBair CS back in July, I had a fairly good idea of what I was getting my hands on, and the top notch craftsmanship of Cane Creek products really needs no elaborating - pulling one of these shocks out of the box is always a pleasure.

As with all Cane Creek shocks it shipped valved and tuned specifically for the intended bike, in this case my 2013 Giant Reign-X. Cane Creek attempts to take much of the initial setup hassle out of the picture for the end consumer by shipping each shock with a tuning guide and a base setting card that is specific to each individual frame. They claim that each shock is set to the proper base setting from the factory for you, so in theory all you need to do is bolt it on and ride with maybe only a small amount of adjustment to taste. Of course I checked to see if my shock was indeed set to the intended settings, which it turned out to be. Time to hit the trail.

On The Trail

I spent the first day riding the shock in the factory base setting as I wanted to see if Cane Creek had done their homework when creating tunes for each individual bike. Much like I found out in July during my initial test session, the base settings are very much spot on, and I would say 90% of the riders who buy this shock would be fully satisfied if they were to just leaving everything as is. However, I am a bit picky about suspension setup, and now that I had the shock mounted on my bike and riding my trails I was really able to dive in and see exactly how much more I could squeeze out of the settings.

First up, with the climb switch turned on my bike became a totally different animal and climbing took on a completely new sensation. There was no pedal bob, no feedback, no quirky platform feeling, and best of all no change in ride height/geometry since the CS does not affect sag. Probably the most striking attribute of this shock when in climb mode is that it retains its ability to absorb bumps with a controlled compression AND rebound stroke. Where most shocks in climb mode have a breakaway point you can sense and no rebound control, the DBair CS just hammers up the roughest climbs without you even knowing it's there. Hands down this is the best climbing shock I have ever ridden, and it does an amazing job of getting my 7-inch travel/30% sag trail bike up the thousand-foot extended climbs that are all too common here in Colorado.

Coming back down, it's hardly a surprise that the Twin Tube technology does an amazing job of controlling the ride. Cane Creek has built a solid reputation around providing shocks with superior damping and the DBAir CS is no different. I did end up settling on settings just a bit outside of the base settings provided, and I do tune the shock differently for trail riding and lift serviced bike park riding.

The adjustment range is pretty vast, but single turns or a few clicks do make a big difference. In the end I liked the shock with a bit slower low speed rebound, and firmer low speed compression. I would attribute this to the fact that I found the shock on my bike really comes alive in the 30% sag range, which on the Reign-X is quite soft; and I wanted to retain chassis stability and control.

In full-on DH terrain this shock shines, and there was very little terrain where I was able to push it past its ability. There was no fade and no change of damping characteristics even on the longest of descents. If anything the shock was so good that it brought out the flaws in the front suspension. Since both wheels need proper suspension to operate more as a system than individual components when talking overall ride characteristics, stability, grip and control, the fork ended up holding me back from really pushing the shock to its potential.

There were a few occasions where I forgot to flip the Climb Switch off at the top of a climb, only to remember part way down the descent as things started to feel a bit harsh in the rough. To be honest though, there were times I forgot and did not even notice as the shock still retains all of its function with CS on. I actually find myself riding in the CS mode quite often on the more mellow trails here as I don't always need the full travel my bike provides and it actually rides better in this setting when the going isn't so rough. I also find this setting extremely useful as a photographer when often times I find myself chasing the world's fastest racers around with a 30 pound camera pack on.

Things That Could Be Improved

First and foremost I would love to see tool free adjusters. Once I had the shock set this wasn't so much of an issue, but it is still a bother to me. Every other shock out there has tool free adjustment and it is something I have simply come to expect. I would even settle for a "tool" that snaps into one of the adjusters similar to the rebound adjuster on many forks. That way I wouldn't have to break out my allen set, nor would the shock have to gain the weight and complexity of adding 4 adjustment dials.

I would also like to be able to measure sag and overall use of travel a bit easier. A graphic on the shock shaft combined with a rubber o-ring makes that part of setting up so much easier. Trying to sit on a bike to gauge sag without this is a huge pain, especially since only a few millimeters change in sag one way or the other makes a huge difference. It is also next to impossible to gauge how much travel the shock is/isn't using through different sections without a rubber o-ring, which I find quite useful when evaluating how a shock is performing. In the end I put my own o-ring on there, but for $695 I would like to see one tossed in with the owners manual.

I didn't have this issue, but I must mention that the small Climb Switch could be difficult to reach on some frames. Even on a frame where the shock is fairly centrally located, it was still quite a reach with the seat all the way up. On a bike with a very low shock position it could be an issue.

And of course then there's the price. Yes, the performance is amazing, but the cost of high end bicycle components is a bit out of hand these days. The DBair CS does make my bike far more enjoyable to ride, but I'm not sure I would trade that for something else that $695 could buy me.

Long Term Durability

I have had this shock for 4 months and ridden and raced it all over Colorado, from the Enduro World Series to Fruita and everywhere in between. I have had zero issues. The CS lever stayed tight (unlike some other shocks out there) so I never had to worry about the climb adjustment switching itself on or off in rough terrain. I also found that it holds air longer than my previous air shocks which is an added bonus.

What’s The Bottom Line?

Without a doubt I can say this shock is on par with the best out there, and a definite upgrade to any bike. On many modern 5 to 7-inch trail bikes it is hard or impossible to climb efficiently without some kind of climbing assist function, and the DBair CS provides this better than anything I have ever ridden. You get all the benefits of a climb setting without any of the drawbacks. I will say that if you are going to drop $695 on this shock and you are still riding an older and/or mid-range fork, you might want to consider an upgrade to the front end as well to really take advantage of how good the DBair's damping is.

Setup is a breeze, so don't be scared away by all those adjustments. Cane Creek has done their homework, and while this appears to be the most complex shock on the market, it is one of the only shocks that practically comes set up and custom tuned out of the box.
