mudguards

[lycra of the lane]

I have a set of Tortec razor guards to fit to my road bike, anybody got any tips on fixing.
they seem a bit flexible to me,or is that just the way they are?

any help out there

I woudl take a guess that they're only flexible when not fitted on a bike... when I'm building up a bike, and fitting mudguards, I always mentally comment on how flimsy the mudguards feel, until they're mounted with various bolts onto various points on the frame...
