I want to buy some pedals off the bazaar. They’re lightly used Dura Ace blah blah 9000 ones, they look swell (good price), buuuuut they have 4mm axle extenders. Maybe you’ve seen them. To me 4mm sounds pretty negligable. My feet are pretty large. I’m pretty sure the extension is there for people who might rub the crank with their ankle. I read some stuff on Q-factor and my eyes were rolling. I’ll probably buy them. Am I being daft?
