Be carefull going for the CCDB Air option. Different frames have different rates of progressiveness as do shocks. A missmatch can lead to a horrible feeling bike. Do a lot of research first. I should have done this with my M9 that has a CCDB Coil which is quite a linear shock. This was causing the ride to be quite harsh on the M9 on landings other than a nice transition. Speed humps were best avoided altogether.
So, off I went and bought a Bos Stoy at huge expsense. This solved most of the issues but calming the rebound down enough so that I wasn’t getting thrown forwards on jumps proved to cause other issues.
On the M9 you can actually change the progressive rate of the frame by mounting the front of the shock in a different position. I wish I had tried this first. I re-fitted the CCDB and after plenty of chat with someone who knows more about this stuff than me I made a few adjustments and now I have a shock that works very well with my frame.
The Bos is WAY easier to set up and ultimately the bike felt bloody quick with it on. I may refit it using the same mounting as I am for the CCDB as a comparison. But at the moment it is up for sale.
The point being, not all shocks are equal, they all work differently so take your time! For what it is worth I fitted a Stoy to my Tracer and it was brilliant. It’s now on my Intense SS1 which I don’t think I will ever sell.
