I think Dave mentioned at some point it's not that big of an issue? FWIW, the old Vivid had a plastic rebound needle to compensate for the temperature differences (warming up would close off the rebound needle port due to expansion), don't think it's a feature on any other shocks though. Regarding my 'making bikes to sell' comment, I've mentioned in the 'companies going under' thread bikes are a bit different to what happens in motorsport - in F1, LMP1, MotoGP and the like, the companies (factories) make vehicles made specifically to race in the racing series, mostly to race...
