Has anybody got any? I need some for my dad who has just bought a used Genesis Core. He’ll be wanting to keep decent sized tyres on but wants to try and stay as clean as possible.

Honestly? just get mudhuggers

i have them , they work as well as anything else and are just a few quid. if they dont work you ca afford to make them into ear rings

Honestly? He’ll probably go “how much? For a couple of bits of plastic!”

Yup, got a rear one.
Spotty dog IMHO..

The front one they do is the standard flat piece of thin plastic that scrolls up to be fitted under the fork crown – absolutely fine and only costs a couple of quid.
The cheap rear one they do is really bad – thin floppy pointlessness. The proper rear ones in the store by me are topeak I think, not seen a decathlon range that was any good, although maybe they have one.

Maybe better with something by SKS or Topeak from Chain Reaction then.
