I've just installed the new OPT shock remote switch for the Cane Creek Double Barrel Inline on my 2015 Specialized Enduro Expert Carbon. I've been waiting for this feature for a long time and I'm very impressed with it. No longer do I have to reach down to the shock and find the small Climb Switch lever while bouncing down the trail. I can keep my grip on the handlebars and modify the ride characteristics of my rear shock on the fly.
I do want to offer some words of wisdom that come from my first attempt to install this. The gold pieces at each end of the cable housing are called collets. These are basically a hollow aluminum bolt with 4 slits cut into each side of the threaded end. As the collet gets threaded in the end of the collet pinches the cable housing. If you thread it down too far it will crimp the cable housing too tightly and prevent the cable from passing through. That would be bad.
In this photo you can see what happened on my first attempt. The collet at the shock mount end seemed to never grab onto the cable housing and so I ended up over torquing it in an attempt to get the cable to stay. The threads broke off inside the black receiver part and I had to get them out using an easy out.
Curious about what I had done on the lever end I backed that collet out to find that I had caused it to crimp with too much of the cable housing extended past the end of the collet. Furthermore it looks like these collets really are a one-time use item as backing it out kinda mangled the threads.
This whole problem was nobody's fault but mine and Cane Creek support was good enough to send me two replacement collets for free. Thank you Cane Creek!
I highly recommend this mod, but be sure you follow the directions and go easy on the torquing of the collets.
