A lot of XC racers are choosing bolt-up axles versus QRs now, it’s one bolt, so not quite the same, but can be done quicker than a QR, particularly if you have an hex key bit in an electric drill to undo it with, F1 style wheel changes!
I wouldn’t take it as a given that undoing/tightening several QRs is quicker than just using a tool.
I’m sure a Maxle type QR is quicker than any bolt requiring a tool.
Lol at carrying an electric drill to do the bolts up, so to save a few grams on a bolt up axle they then carry a tool weighing 10 times what a QR bolt would be.
I just cant see where this setup is better.
