    Default Ritchey Alpine 'JB' tire, actual width?

    These seem like very cool tires but not much info about them out there....

    https://us.ritcheylogic.com/us_en/bi...alpine-jb-tire

    Wondering what the actual width of the 30mm version would be on my 19mm inner width rims (running ~60 psi). Anyone have these tires?

    FYI Ritchey says 30mm on 21mm inner at 60 psi, so these are slightly undersized.

    Mine come out at exactly 28mm on my 21mm rims

    Interestingly, they’re described as 28s here also (although I’ve never seen a JB in anything but 30c and 38c versions. https://granfondo-cycling.com/ritche...eel-stallions/
