    the pedal strikes back

    i have a question regarding clipless pedal strike.

    given one's shoe sticks out farther to the side, front and back and with all other things being equal, isn't the angle at which pedal strike occurs going to be the same on flat ground for any given pedal?

    considering the case of turning into an incline, i'm not sure how much difference a flatter pedal is going to make. it would seem that someone using speedplays wouldn't be able to turn more than someone using a look pedal. isn't the shoe is going to make contact with the ground first?



    a long time ago, in a galaxy far, far away they had pedal strike proof bicycles:

    I had pedal strike today, but it was my geared bike. That thing has a 113mm BB spindle, so I think that is part of the cause. Plus the BB is a bit lower than it is on my fixed gear, but really not by much.

    Anyway it was definitely the pedal that hit, not the shoe.

    I doubt it. Your foot is elevated higher than the pedal and I've never seen a pedal system that leaves your foot hanging over that much. Maybe with that crazy side mount cleat system, but not with anything pratical and common.

    Best way to test: Take your shoe off your foot. Clip it into the pedal. Position pedal so it's at the bottom of the stroke. Lean bike over. Which hits first, pedal or shoe? Report back immediately.

    when I lean into tight turns, at the bottom of my stroke, I point my toe so that my clip (I use clips and straps) DOES strike first and I can guage the pedal strike based on that

    By using a narrower pedal, your foot becomes the thing that will scrape first. with MTB style platforms I used to scrape pedal all the time. with track style platforms, my shoe scrubs occasionally, but at a greater lean angle than the pedal struck.

    In other words you get less scraping with a narrower pedal, AND scraping a shoe is way different than pedal strike. a good hard pedal strike will bend your pedal and lift your rear wheel off the ground. A real pants crapping sensation. Scraping a shoe is no big deal at all. Shoes give, pedals don't.

    Admittedly, this is from a Speedplay marketing brochure, but if you trust that they didn't manipulate the photo, it's a pretty clear demonstration of the whole cornering angle/pedal size relationship:
