With mountain bikes, what do you think is more efficient: highly preloading the fork and using low tire pressure or having a "bouncy" fork and hard tire pressure?
I like to have the fork with quite a high pre-load and then I set my front tire to around 1.8-2.0 Bar (around 25-30 PSI). I think this gives me good response on the fork, not wasting much energy and also gives me good control on technical zones, specially descending. I sholuld also mention that my fork (Rock Shox Tora 302) has remote lockout which I mostly use in asphalt and technically-easy zones. Bike frame is made of aluminum.
On the other hand, I see some of my colleagues having soft forks, which IMHO bounce quite a lot, and they say they inflate their tires to almost maximum pressure possible.
Also, to what extent is rebound control important here? I like it to be more absorving than bouncing.
