So all this talk about pedals brings up something that's been on my mind.
I'd prefer to use SPDs—or something like SPDs—because the cleats and pedals are robust, replacement cleats are easy to carry, and the shoes are walkable. But I ride with a very toes-out stance that SPDs don't afford, and after a certain distance my knees really hurt. I'm using Speedplays just because they let me get that stance, but during the TABR, the weather was rough on both the pedals and cleats.
I see that Eggbeaters (to pick one example) allow more float than SPDs, and I know there are other SPD-like pedals out there. I'm wondering if anyone has experience customizing the position of SPD cleats or using SPD-like pedals (that are in production) that might be a good alternative.
