The spirit of this board is to compile and organize wheels and tires related discussions.

If a new wheel tech is released, (say for example, TPU tubes, a brand new tire, or a new rim standard), feel free to start the discussion in the popular "Road". Your topic will eventually be moved here!

Thanks! Updated and averaged out. Measurements of 28mm were lower probably due to a lower PSI, I'd say that 55 is below average for a 28cc.

For complete reliability, a 3rd dimension with PSI should be added. Maybe once we get more data.

Interesting, I'm pretty heavy at 84kg and Zipp recommends 57psi all round for the dry. I tend to go a little lower in the winter given the roads are often damp.

For reference, my measurements posted up thread were at 60 PSI.

STR on 25mm internal, hooked, 60 - 65psi
28mm 31.2
30mm 33.1
So a bit bigger than some.
