Fabio Jakobsen’s tyre and insert blown clean off his ‘mini-hook’ rims in UAE Tour crash

A spare bike was obviously needed, too, as the tyre and foam insert were both wrapped around the frame and no longer in contact with the wheel at all.

It is unclear what exactly caused the crash, which was not clearly captured by the television cameras. The peloton was strung out on a false flat on a wide road, and when the cameras caught up, Jakobsen was picking himself up off the ground along with Ethan Hayter, Daan Hoole, and Robbe Ghys.

Jakobsen appeared to be using the Proxima R 60 Team Edition model from team sponsor Ursus wheels. Interestingly, he was riding unbadged tyres in recent stages, which look to be a new version of a Vittoria Corsa Pro Speed, which has recently been released in a 30mm size, though this is unconfirmed.

The pairing of tyres and rims has been a hot topic in recent years in the wake of a number of blowouts on tubeless set-ups. Foam inserts are used to keep the tyre on the rim in the event of a catastrophic and sudden loss of pressure, and also allow riders to ride on the insert in a ‘run-flat’ scenario.
