Flat rubber!

I just bought a floor pump with a pressure gauge for the first time. Before this i just relied upon a basic hand pump and my 'calibrated finger nip' on the rubber. Guess what? - my average PSI was 20-25!!! Dohhh! So I've been riding around for the last few years at below recommended PSI shown on the tyre wall. I never knew any better and didn't give a second thought. Just been out for a ride on my hardtail with with 50PSI in my tyres - WOW what a difference. I'm going to hit the trails this weekend on my full-suss bike at correct PSI and see the difference. Should be the best £40 spent on my bike.

    There is no real correct value though - just a range that may suit you.

    50psi may be a bit too high on some surfaces, but experiment.

    50PSI is far to high for trail riding with drops and jumps ect ect, you will get bounced clean off at that pressure.

    I run around 40 in the front as a max.

    I run around 30-35 the rear depending on the type of trails I'm hitting

    I wack it up to 50 for XC/training rides :)
    I use all 9 inches.

    My track pump seems a bit out to be honest, about 40 PSI seems fairly rock hard. They're good to ensure you always get the same PSi when you've found a setting you like, I wouldn't be too set on using the "right" number though.
