It's always safe to assume user error in the no-speed clipless fall. But I've been riding clipless for years now, and I think what I'm dealing with is equipment failure. I'm just not sure where the problem is. Looking for your diagnosis advice.
• Pedals are three years old. They seem to be in decent condition, spinning freely but not wildly. (They are Shimano 520 mtb pedals, standard-issue commuter type.)
• Cleats are maybe a year old. They look worn, but they always do.
• Pedals were recently moved to a new bike. Previous bike was fixed gear with relaxed touring geometry. New bike is decidedly more "racy."
• Never had a problem until recently with unclipping; now it is almost impossible to swing my heel out to unclip. Drawing heel in, however, works fine. (But it feels completely unnatural.)
I wonder whether the new position I'm in (combined with the age of the pedals) has made it impossible to unclip as I always had. Or maybe now that the pedals are not on a fixed gear the tension doesn't need to be so high?
I'd love any opinions.
PS: I didn't think it was important, but upon reflection it occurs to me that a neighbor in my building could be routinely urinating on my right pedal in the middle of the night. That could factor in.
