I've been looking to get some spare brake blocks for my old Campy Chorus (circa 1993) brakes. I haven't been able to locate any of the type that I bought last time (BR RE500), but I have been able to find a more recent type (BR RE600). I'd kept the old blister pack, and they look pretty much identical. Can anyone tell me whether they (BR RE600) will fit into my shoes, or am I going to have to look harder (probably mail order) for some BR RE500s, or even buy some new shoes or even whole caliper sets (hope not)?
