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 because of the trigger. Effectively, because of the 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.
In the course of the crash, the tire practically got here off the rim fully leaving the Vittoria tire liner flapping within the breeze. Since then there have been many questioning the compatibility of sure tires and hookless rims, together with the Cyclistes Professionnels Associés whose president, Adam Hansen, has voiced the CPA’s concern over hookless rims within the Peloton.
As a refresher, hookless rims remove the small hook on the rim which previously has served to lock the tire bead in place. Hookless rims as an alternative depend on the form of tubeless tire beads to carry the tire in place with friction in opposition to a straight facet wall. The benefit is supposedly a lighter rim with a lowered probability of pinch flats and impression harm 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.
Nevertheless, hookless rims have particular necessities for tire sort, measurement, and strain – with most hookless rims required to run under 72.5 PSI.
