Actually these are getting harder to find as I noticed that 6 stores in Europe suddenly all went "Out of Stock" at the same time. I assumed some lawyers were behind it all, especially after reading about other instances by Speedplay trying to control their products post-purchase...
I finally got confirmation from a shop after waiting on back-order for 2 months that they will not be receiving any more of these.
Perhaps some rebels will make some in their garage, but I don't think you'll be seeing them sold at online shops any more.
Yes, I also have bowties that don't fit (you referenced the post in this thread). Maybe they are nanogram or Zero plates... I tried filing the plates so they will fit on the pedal and used my old (shorter) screws... however, the performance was awful as the plates still had a slightly different curvature or transition from the pedal body. I could clip in but they clipped out very easily. I never actually rode with them.
Due to laziness and stubbornness, I left my original BTP bowties on even after they started looking horrible. Still work the same, just look very worn out. I think I've got 12,000 km on them. Probably will not last too much longer. Incidently, my cleats are actually lasting longer with the ALU bowties... as the bowties wear, it contacts a slightly different area on the metal cleat spring - so they wear out together... until they explode in harmony
