There are a few things that can be done to help prevent the slow air leaks that some shocks suffer from. I would like to add abit about the DRCV system, the concept is pretty good, but it doesn't seem to work as well in practice as on paper. If you are determined to go down the RP23 path I would get the biggest air can that you can and a custom tune to suit. IMO I would work with your Trek dealer in the first instance for tuning advice and maybe a changeover or maybe have the DRCV rebuilt by a suspension expert such as Tekin or NS Dynamics to sort out your issues.
My concern with going to an RP23 (or any other air shock) would be that you may not get full travel as the air spring will ramp up to much towards the end of its travel. If the second stage of the DRCV did not open up you would need a falling rate deeper in the suspension travel to allow the bike to use the full suspension travel.
deeper in travel the second part of the chamber gets opened up so the air spring does not ramp up so much - which allows for the slight rising rate. This is a similar leverage curve that you would expect for a coil sprung bike as opposed to air and appears to be consistent with the marketing of the DRCV and how it is supposed to work. What I have done is posted the leverage curve for a 2012 Remedy which may be of some assistance.īasically it shows that the Remedy has a slight rising rate for most of its travel and then for all intents and purposes levels out. I don't have any direct experience with a Remedy, unless looking at one in a shop counts, but given you haven't received any feedback yet here is my 2c.
