The evolution of a mountain bike: Rear shock upgrade (Build 5)

So a local pro and R&D rider had a workshop-garage sale of parts he had tested or used to test new frames and I managed to get the correct length Canecreek Double Barrel Air with Climb Switch (CCDB Air CS) for my Nomad. It was hardly used and a good price so I went for it as it could only be an improvement over my much tinkered with Debonair.

As the knee is only two months post surgery I certainly will not be able to explore the full range of the shocks capabilities yet but I am hoping that it is an improvement on the Monarch.

New Tyres

Whilst I was tinkering in my workshop I decided to experiment with some new tyres. I had noticed that riding in Pemberton was really hard on tyre sidewalls so I thought I would try the WTB Breakout 2.5″ with the TCS Tough case. So a High Grip for the front and a Fast Rolling version for the rear and we will see what happens.

Bash Guide

I also took the opportunity to install a Blackspire Trail-X chain guide and bash guard.

Update on the Rear Shock:

The CCDB Air CS is worth the money. It is not quite as sensitive as the Debonair in the initial travel but it is pretty good. More importantly it holds up in the mid travel much better meaning less pedal strikes and less wallowing. It has a great tuning range, each click means something and being able to separate out the HSC, LSC and Rebound is fantastic.

The tuning guide that comes from Cane Creek is easy to follow and it is just a case of going through your “shock set up trail loop” several times to find a setting that works. I found 35% sag with only 180 psi and the settings that seem to work for me (@220 lbs) are:

LSC: 7 clicks.

LSR: 9 clicks.

HSC: 1.75 turns.

HSR: 2.25 turns.

It does not take a lot of LSC to tune out the effect of a rider when pedalling leaving a sensitive but robust rear shock that performs well and allows full use of the bike’s travel.
