Sorry to hijack – currently run an 08 Heckler with a 09 HV RP23 which I was not overly impressed with – I will explain -When i run the recommended sag (13-15%) the small bump compliance was shit and it was very easy to blow through all the travel on big hits, the pro pedal was not noticeable even in the firmest setting. I read on mtbr about this problem and a few people have put a shim inside the HV air sleeve which in effect reduces the air volume, it is a very easy, no cost mod to perform. I did mine (if anybody wants the link then i can email) and the shock was a lot better – I run 10-15 psi less which means run more sag so get more small bump compliance and the shock now does not blow through its travel and on the big hits I fail to bottom it out which is a great improvement. Incidentally it is a 2009 HV RP23 with low compression tune & rebound.
However I have spoken to TF and they say if I want to go for a Coil then the Van R is plenty good enough for the Heckler rather than spending more on a DHX5!
I am going to try a Van R Coil (£210 @TFTuned) and expect a significant improvement over the RP23!
Konastoner – Coil will always feel smoother over air!
