If you have V rake bosses, Decathlon make these, and they are great. Clamp on the matching front one isn’t great though.
Many thanks for this. This is my fourth attempt at finding a rear guard that works.
Tried the crudcatcher and it strips before it tightens.
Tried the revolution, which attaches to the seat post with a fabric ‘belt’- rubbish.
Tried the Topeak 2, again strips on height adjuster and the plastic on the quick release is like putty.
Fitted the decathlon number and it looks as though it will actually do the job! I didn’t realise it was quick release into the bargain. A great buy, thanks for the tip.
