Just 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. Effectively, as a result of potential trigger as nobody can say for sure what triggered the crash, however we do know that De Gendt was using hookless rims and tubeless tires with a tire insert.

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 probability of pinch flats and influence 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 sort, dimension, and strain – with most hookless rims required to run beneath 72.5 PSI.
