I've never seen these Giant SPDs before, but found them in nearly new condition at a bike swap meet for $20. I love them, easy in and out, and it looks like the silver cap just screws off to service the bearings. I use Campy quills , toe clips and straps for Eroica, but the rest of the year, its SPDs on all my bikes, but previously Shimano. Anybody else use these? I don't see a model no. anywhere, no idea of their age.
Found some nice red cloth tape too, $25 total.
