    Ha -answer is ‘it
    Ha -answer is ‘it depends’

    105 sounds reasonable, I’d you feel reasonably comfortable and quick then it’s right. Worth experimenting though.

    Otherwise..

    Follow manufacturers guidelines for your weight (if specified), take into account road surface you’re riding on that day -lower pressure for rough surfaces – and type of riding (I always go higher for TT’s)

    Clinchers will also have a specified max for the wheel, tubs can go loads higher. I’ve had anything from 100 – 160, depending! But I’m quite heavy..

    very interesting, one thing
    very interesting, one thing I have noticed is my tires after a 80k ride drop pressure from 110psi to 85psi, that measurement I gave taken the last three 80k rides I have done.

    proving the point that you should alwsys check your pressure at least before anything over 20k

    It depends a little bit on
    It depends a little bit on the tyres you’re using but as a rule the front should have 10 less than the rear and as above 105 is probably high.

    Personally I think the article suggests pressures that are a bit low for my liking (round about 80/90psi for me) but it’s in the ball park. I’d also say I add 10 for good surfaces (racing crits, riding in France) and another if I’m on my race tyres as they’re extremely supple.

    NO. Not unless you are on
    NO. Not unless you are on 23c’s and weigh 100kg. Follow this PDF, it’s science. Anyone else is wrong.

    Your arse, hands and times will thank you.
