I'm installing a set of Lyotard 45s on my SL cranks and wanted to add toe clips (the old steel types with the leather straps). I'm wondering if its a universal fit- could I just buy an old campy set or a newer MKS set?
Although the Campy toeclips are my personal favorite, they have a triangular tab to help guide the toe of your shoe into the clip:
If the Lyotard pedals don't have an opening in the center of the front cage plate (the mod. 45 cage design seems to have changed several times over the years), then the Campy toe clip won't fit.
You should have no problems with a standard MKS or Christophe toeclip, though, as long as you avoid the models with the wide mounting bolt pattern.
