CCDB - It's a tight fit!
I have just carried out a frame transplant to move from a large 05 HL Spot to a large 09 DW Spot. I had left my CCDB on the HL frame and so far only ridden for 2 hours on the DW with the standard RP23. Note: RP23 weighs 288gm, and CCDB with 400lb Ti spring weighs 668gm.
Apologies for the camera phone photo quality (taken in the kitchen!).
I checked the mounting hardware and thankfully found that Turner carried the dimensions of the old Spot mounting over to the DW frames.
I initially mounted the CCDB (the right way up) without spring to test full compression for contact points.
As you can see it fits but it will be very tight if the bottom out bump stop is fully compressed under a maximum travel impact.
I have seen a number riders fit their CCDB's inverted, but this will not work on a large DW Spot frame. Although the shock will mount, the adjusters will start to impact the down tube after about 1/3 compression.
With the shock the right way up again and with the spring fitted, there is potential if the rear mech cable is not correctly fitted of it being trapped in the coils if the spring gets close to being coil bound. I used the relatively new Goodridge gear cables which are much stiffer than previous cables, so this should not be a problem.
I have not ridden the DW Spot with the CCDB as yet (hopefully tomorrow), but the initial impressions are that the suspension moves much more easily than with the RP23. I do not know if it will need a re-shim, because I undertand that Iron Horse DW bike needed lowered compression (or similar), with CCDB's.
Finally because it is always requested, a side on shot of the complete bike (with RP23). Note: the rear brake fitting is temporary arrangement to get my Hope Mono M4 IS brake to mount on to the post mount fitting. Formula brakes have been ordered, but in England at least they appear to be out of stock until Feb 09 (if later I will probably hold out for the new R1's).
