Initially found the Crud Road Racer ok, fitted last winter and they perform very well when they’re not falling apart.
Easy to fit IF you follow the instructions, don’t rub, offer good protection.
However I’ve lost two front extentions, which break if you breathe on them too hard, never mind touch them with your toe (avoid if you have overlap) and broke one stay putting the bike in the car.
I would have recommended them wholeheartedly when spares were sent out on request for the price of a stamp.
BUT:
Now Mr Tomkins has started charging between £4.50 and £6.50 for spares packs, I’m beginning to think they’re a bit of a liability and will replace them with Race Blades next time they fail.
EDIT:
And, of course, as pointed out above, you need a caliper brake to attach them, doh!
