Zefal Shield G50 gravel fender review - great value, simple and sturdy guards

A great chunk cheaper than the alternatives these guards punch well above their weight. Just don't expect to fit them quickly

Cycling Weekly Verdict

The Zefal Shield G50s fenders / mudguards do an excellent job at protecting both you and your gravel bike from the winter wet and filth. They'll take up to a 50mm tire, have a really solid construction and are nice and stable even on fast and rocky trails. They're a bit heavier than some other guards and a pain to fit but given they cost 60% of many other guards we're ok with that.

Reasons to buy
  • +

  • +


Reasons to avoid
  • -

    Time consuming and awkward to fit

    Attachment points collect lots of dirt
