Subject: [CR]Shimano Dynadrive toeclips - Continued

I seem to be answering a lot of my own questions lately. After posting about the Dynadrive toeclips a couple of days ago, I dug through the parts bins and found two or three pairs marked "L" and one marked "M" in addition to the originally discussed one marked "LL". Did some measuring.

The Dynadrive clips are adjustable similar to Campy C-Record. An "M" adjusted to maximum length is 11 1/2 cm from the back of the cage plate to the front of the clip. An "L" adjusted to minimum length is a bit more than 11 3/4 cm. I measure a Christophe medium clip mounted on Atom 404 pedals at 11 1/2 cm and Christophe medium mounted on Campy steel road or Campy SL road at 11 3/4 cm. So it appears if one uses a medium European clip, the Dynadrive medium would be at the low end of the range for European pedals/clips, and the Dynadrive large at the high end.

DynaDrive was kind of a cool concept, although not really original to Shimano, as similar pedals were made by Hi-E earlier and by French and/or English manufacturers even earlier than that. But Shimano abandoned the design several years before the clipless pedals took over. BTW, there was also a Dynadrive DeOre pedal that used conventional rather than adjustable clips. Original road DeOre stuff, not the later MTB components by that name. The original DeOre I think is one of the most interesting gruppos Shimano ever made, definitely influenced by the stuff used on French constructeur bikes.
