I won’t go into too much technical detail but this shock is buttery smooth and allows for limitless adjustability. I initially was a bit scared about the complexity of this shock but the base tune/fit guide on canecreek.com made setting up the shock a breeze. I does take some time and requires a couple of rides to get that perfect tune but once that is found then you are left with a very impressive shock. No matter how much abuse, brake bumps, flat landings you throw at this thing it just eat everything up. My Double Barrel is currently on a 2013 Specialized and it works perfectly together. Before owning this shock I was a very “set and forget” rider but this shock has me doing a bit more tinkering when the terrain changes and I think this is for the better as now I can get the most out of the shock depending on the environment being ridden. In regards to adjustability you have your high speed and low speed compression along with high speed and low speed rebound, which really allows you to get a custom tune for your bike and riding style.
One other great thing I also noticed that with this shock on the bike I find myself more stable on the trails, meaning that I can track significantly better, the shock seems to just stick to the trail. Overall I would very much recommend this product, although it is very expensive it does do its job very well.
Lastly, one additional item I like about this shock is that it comes with a little tool that helps with adjusting all the knobs but also will help when you get dirt and gunk on the shock body, the tool helps to adjust the ring and the spring. This is a huge help as all my other shocks seem to seize up and then require a lot of effort to adjust the spring/ring.
