What inspired this gripe was a pair of Exustar pedals that I'd bought years ago as backups that are "compatible" with Time Atac. The time came that I needed the backups and the Time system doesn't have a lateral adjustment.
So this is really all about my dissatisfaction with one product. But thought it was curious that nobody ever does publish a number for this. I like keeping my feet close together, I'm running the old, very narrow D/A 7410 cranks and usually have pedals and cleats so my feet just clear the arms.
