I’ve known of this website because my local bike shop recommended it. I’m not ripping anyone off or selling dodgy ware.
It’s a pair of cleats and they’re not cheap. It’s not worth my while chucking them away and frankly 50p is not what they’ll sell for.
They’ve definitely not been used if that’s what this forum is about. They’re as good as sold by online retailers. They’ll work fine on Shimano, Mavic and Sidi shoes all of which have three bolts for fitting the cleats which go on the sole of the shoes.
