Metal Mudguards Safety Stays

[irc]

I am thinking of buying a set of 700x50 Velo Orange mudguards.

The front stays don't have an emergency release like many plastic muguards.

Would these ones work?

Or is the risk of metal mudguards collapsing and locking the front wheel smaller?

There is indeed less danger with metal mudguards. The mechanism of wheel lockup is of the stays bending, the bottom mudguard edge catching the tire, and then the mudguard crumpling and packing the space between what remains from the mudguard and the tire, with the overall space contained by the stays. A metal fender would likely crack somewhere on the way if it even managed to initiate the process.

In fact, the straight stays are held at the fork end by a “draw bolt”. A bolt where the stay passes through a hole in the bolt, and is only retained by friction between bolt and stay as you tighten the bolt.
If you (say) use a self locking nut which won’t shake loose and plastic or fibre washers you can arrange it so the stay will slip through the bolt under extreme pressure, such as is generated by a mudguard jam.
The manufacturer may have already thought of this

Thanks for replies. Lock nuts it is then.

re colin's comment; a spring washer [in the right place] can also turn a standard drawbolt fastening into a 'safety release'

If you're not happy with the idea of the drawbolt and the stays are around 4.5mm, SKS do a breakaway fixing for their single stay guards
