Wow, lots of discussions about pedal threading lately (here & here). Very insightful comments & interesting history from everyone, but was it ever determined for sure that becnal's captain cranks are backwards? If the pedal with an "L" on the spindle installs into the left side of the bike (reverse threaded) and the pedal with an "R" on the spindle installs onto the right side of the bike (normally threaded), regardless of chainring location, then everything is as it should be. SPD shoes will clip/unclip fine. I just hate to have becnal stuck with platform pedals, or even worse swapping spindles on SPD pedals (I've done this - kind of a pain) for no reason ...

Good luck!
