Not sure if it’s really relavent as I’d not expect to find myself 5ft off the ground (and sideways, and heading for the ground at the wrong angle)too often on a CX bike, but on a particularly bad (crash) landing I managed to rip the QR axle out of the dropouts on my 29er.
And that was without bending the crest rims!
It’s one of my main reasons for looking at suspension forks for the el-mariachi, to get a through-axle (rigid TA forks are slmost as much as the suspension ones!).
I suppose it’s a race bike, they’ll have decided a 15mm axle is lighter than the extra reinforcement it’d need with a QR to cope with a disk brake?
