Lately on the UAE Tour, Lotto Dstny rider Thomas De Gendt hit the deck. However in contrast to many run-of-the-mill crashes in professional biking, De Gendt’s crash ignited a firestorm of media consideration as a result of trigger. Properly, as a result of potential trigger as nobody can say for sure what brought about the crash, however we do know that De Gendt was driving hookless rims and tubeless tires with a tire insert.
Through the crash, the tire practically got here off the rim fully leaving the Vittoria tire liner flapping within the breeze.

As a refresher, hookless rims remove the small hook on the rim which up to now has served to lock the tire bead in place. Hookless rims as a substitute depend on the form of tubeless tire beads to carry the tire in place with friction towards a straight aspect wall. The benefit is supposedly a lighter rim with a lowered likelihood of pinch flats and affect injury to the rim whereas permitting the tire to fill out a extra rounded profile and run decrease pressures for higher grip.
From a producing standpoint, hookless rims appear to be simpler and less expensive to fabricate, which hypothetically leads to a extra reasonably priced product.
Nonetheless, hookless rims have particular necessities for tire kind, measurement, and stress – with most hookless rims required to run under 72.5 PSI.
