    Wow, I'm 80kg and running 81psi front. Will try a bit lower.

    Wow that's low!

    I think that's not too crazy.

    Some numbers for comparison:

    I run my 28mm Panaracers 75/80 F/R and weigh 79kg. It really doesn't feel overly soft, could easily go lower.

    My Veloflex Masters 25 measure 24.5mm on Neutrons. I run those 80/85 F/R. Sweet ride.

    These low pressures are a whole new world for me.

    I'm still nervous that too low will result in pinch flats because I have to deal with loose gravel on some chip seal country roads.

    I think you'll find the sweet spot for pressure. I'm heavier than you and never pinch flat. My Zanconato has 28mm Vittorias and It's pretty plush. I've ridden them as low as 60. Finding the sweet spot between too hard and becoming floppy soft is only achieved through trial and error.

    And don't forget we are all using different gauges of differing accuracy.

    Good point.

    Today I lowered the front and back to 60psi - as indicated on my 40 year old Silca Pista anyway. So nice!

    When I'm not riding it.....I'm staring at it!

    You can find them just about anywhere...but this is so worth the small money. Pump gauges are notoriously very off which becomes more and more important as you go lower in psi (if I remember my jr high math right about percentages of a small base etc).... https://www.jensonusa.com/Meiser-Acc...Pressure-Gauge

    40 miles today at 50psi was just a little too low. I think I'll settle at 60.
