• Hookless are very much tubeless specific!

    Or, to put it another way, hookless is just a return to the way things were before the introduction of the exotic "crocheted" high pressure rim. It was always good for 45psi on 27×1¼ tyres with steel beads, the crotchet allowed us to reach the dizzying figure of 60psi 🤯

    The tubeless-specific part is a shelf and retaining hump for the bead, not the hooklessness

  • not sure Brad was after buying 27x1 1/4 rims

    The comment applied equally to 700×32C for the few people who indulged in French practices back then.
