Speeder – if you look at the picture above I posted of my DHX you will see its the version with the dial at the back rather than the three position pro-pedal switch; because this becomes a low speed compression adjustment after the modification the dial adjustment DHX is the better shock to modify. This was the advice from Craig last year but he is constantly fiddling with his kits so this may have changed… and to be honest, I am so happy with the basic set up that I have hardly touched the adjustments (and I was a constant fiddler with the CCDB I had before this as I could never get it quite right). Avalanche are now modding Float-X shocks as well. When Craig was doing my DHX he discussed how this type of shock is prone to pushing air into the oil and hence they require more frequent servicing than coil shocks, and its a price that has to be paid for any air shock. I got a local guy to service my DHX after it started squelching as I had indeed pushed air into the oil (6 months and the Trans-Savoie of use).
On a side note about the more basic Float/RP23 type shocks I have a Float R which TFT did a PUSH modification too. It took two goes with TFT to get the set-up pretty good with the Float R; and as a normal use shock I am very happy with it. The way it is set up it sits quite high in its travel (a bit like a BOS VIPr) and there is good control even when the going gets gnar, but other shocks I have tried feel better hence my constant faffing and geekery. Had I not tried other things and if I were less of a geek I would probably be happy with the Float/Float combo but to try things and be looking for improvements is a hunt for a needle in a haystack. The Float shock worked well with the Fox 36 RC2 fork I had, but not with the Marzocchi 55 RC3-Ti fork, and the Marz fork worked well with the CCDB but I stuggled with the CCDB and the Float fork – I like a ballanced feeling suspension set-up.
Summary of my suspension geekery (there are a number of threads on this) – The basic Float/Float combo worked best with about 20% sag and was a great XC/Trail set up; but when I dropped the pressure to get 30% sag and improve the doonhall performance the shock and fork would pack down and bottom out etc. The Push kit on the Float shock improved this and I could run lower pressures in the shock getting closer to the 30% sag of the Marz fork, but it still feels like it wants to run higher in the stroke. I preferred the plusher 30% sag set up with the Marzocchi 55 RC3-Ti and the CCDB, although there was brake-dive and shock-wallow with this; better at high speed stuff but scary in low speed techy riding and not great for out of the saddle honking or pumping the terrain.
Ideally I wanted the 30% sag and plush DH feel of the Marz/CCDB with the low speed control and reduced dive of the Float/Float set-up, and thats what the Avalanche tuned 55 and DHX-Air gives me. I’m able to run 30% sag and have plush suspension without having brake-dive and wallow in low speed techy manouvers, or pack-down and bottoming out on big/square hits. What I have also found is that the fork and shock work fantastically well for pumping terrain where it feels like a big hand is pushing the bike along the trail as you pump the little rises and falls, and getting out of the saddle and honking is not a huge chore as the fork and shock only seem to use part of the travel when riding in this way… my Avalanche tuned DHX and Marzocchi fork combo is stunning.
I’m testing a lovely bike at the moment and the Pike fork and CCDB-Air shock work well together but I miss the magic of my own personal Avy set up (but I want a longer top-tube… and possibly wheel-size!!!).
Beware the geekery!
