sherpatony Posted April 13, 2010 Report Share Posted April 13, 2010 I know there's always talk of the magic 4 psi in the trials world. but what do most of you run front an rear and do you change pressures for different conditions?

shercoman2k8 Posted April 13, 2010 Report Share Posted April 13, 2010 4 psi Rear in dry conditions, 3.5 or even 3 in slippy conditions. Front around 7 all conditions. Quote Link to comment Share on other sites More sharing options...
jimmyl Posted April 13, 2010 Report Share Posted April 13, 2010 Modern bike, modern tyres, normal body weight -4psi rear - 5.5 psi front. Drop rear for very soft and muddy going or if riding easier routes. Check pressures if change in temps - ie cold night - sunny morning. Tyres can gain 1 psi easily in theses conditiions. Don't park bike in the sun before checking - black tyres absorb a lot of heat energy if left in the sun. Quote Link to comment Share on other sites More sharing options...
