i was advised by john hackett not to fit the frame ones as they can do more harm than good. i know other say otherwise.

so i didnt fit them on my DD bike but i do have fork ones one there.

Lee, thanks for the picture. Your bike looks very clean and I like the mudguard.

Lots of carbon as standard on the S4r:D:D its not as clean now :lol::lol: it was brand new then:o:o

Yeah I think at high speed they will do frame damage got mine mainly for those low speed slids in the wet :o:o

Though if you look at the R&g ones the bolt for bung to attatch to machined ends is very short so in a high speed crash i would imagine it would shear off:D:D
