Any one tried them on 32mm tyres?
Road CC say they are a bit fragile. I’ll mostly be using them on tow paths and Sustrans routes, so they are just to keep water off me really, but I wouldn’t want something that breaks if I do get it packed with mud.

If you have them already the go for it.
I wouldn’t choose them over the sks ones.

Biggest they’ll cover is 25mm & you need a caliper to attach them too.

If you’re looking for guards that’ll attach to a frame without mounts, try Axiom axle runners.

I couldn’t make them clear 25mn, had to put 23s back on. Even then the slightest thing on the tyre and they’re grinding away.

Wiggle have the zefal croozer/swan pack for under a tenner. They’re like a thinner version of most MTB guards – I got a set for when I inevitably get fed up with the roadracers.

Roadracers worked fine on my road bike with 28s

Planet X are doing some Vavert guards for about £13. Look very good – planning on picking up a set

The set I had fell apart. The heads on the little plastic screw things seem to break off very easily.

I can’t get mine to fit 25mm Aksiums without letting some air out so clearance must be in thou.

I use the Zefals above. They are great although the rubber straps perish quickly (I use the rubber bands from a crud guard). Do a decent job of keeping me dry although not much use in a group as guy behind gets soaked from rear wheel !

Thanks for the various suggestions.
Those Zefals look good, except that I would prefer something that extends forward of the fork to keep the spray off my face.
The SKS Beavertail looks like it would do a better job for not much more money.
