TwoPuckShaker on January 6, 2025 2:17 pm 27 1/4 is 630. It’s sightly larger than 700c (622). Your wheel is 700c
MasaTre86 on January 6, 2025 2:17 pm If your tyre says 630, then the rim is likely 622, the most common rim size. You have to take the measure at the tyre bead.
BuskattenJanne on January 6, 2025 2:18 pm Come on man.. It litterly says “32-630 (27×1 1/4)”.. It can’t be that hard..
ChuckofMostTrades on January 6, 2025 2:21 pm How are you measuring the rim? Looking at that rim I’d definitely assume it was a 700c, not a 27″ rim from something from a 70s road bike…
