SortingPedals

Sorting pedals means getting rid of bad ones, sorting the good ones by size and by material (plastic or metal), and then making pairs if they have become separated. Although it seems easy to sort pedals, take care, as pedals are very frequently mis-sorted.

First, the hard part: you should know how to tell if a pedal is bad as pedals get hard use, so many we have are bad, and we don't want to sort or store bad ones.

Bad means: visibly broken body; missing end caps; loose or badly bent cages, or bad bearings.(need picture here) Bad bearings are hard to tell when the pedal is off the bike, but here is the best way: Hold the spindle in one hand and the body in the other, and move the spindle up and down. (need picture here) If it doesn't move at all, the pedal is probably OK. If it moves a lot, the pedal is probably bad. If it moves a little, do this: turn the spindle while holding it hard (up or down) against the pedal body. If it feels sticky, it is probably bad. If it turns fairly smoothly, it is probably good.

This is where a "Don't Know Pile" is very useful: you will find some pedals that are nearly new, and some that are clearly bad, but most will be someplace in between. For the hardest ones to figure out, it will save time if you put them in a pile for someone to help you figure out later: we call this the "Don't Know Pile."

You can now sort the good pedals by size: There are two sizes: 1/2" (we call "skinny") which fit on one-piece cranks, are used on lower quality bicycles; and 9/16" ("fat"), which fit on three-piece cranks on higher quality bicycles, and are more useful to the co-op because they are in demand.

We use 9/16" crankarms as sorting tools for pedals. If you try to insert the spindle into one of these crankarms without screwing it in and it goes in, it is a 1/2". If it is too big to go in without turning, it is a 9/16". (need picture here) It is possible (but hard) to tell the difference by just looking, so resist the temptation to try, because no matter how experienced you are, you will eventually get bored and make a mistake, causing the person who picks out the pedals you mis-sorted to curse you when they find they got the wrong size. Use the crankarm tool, and make someone happy with a good pair of pedals they can use!

Once sorted by size, pedals are paired, left and right. Left pedals always have left-handed threads, and right pedals always have right-handed threads. They are usually stamped with a "R" or a "L" on the spindle end or wrench flat, but you can always tell which way threads go by looking very carefully from the side: left handed threads slope up to the left, right handed threads slope up to the right. (move below picture here)If you have a left pedal and a right pedal with bodies and cages that look exactly the same, they are a set, and you can fasten them together using plastic zip-ties.

Finally, we sort the good, paired, pedals into three separate crates for each size: all-plastic bodies, those with any metal in the cage or body; and those that have toeclips on them (don't worry about the straps). Good single pedals can go all together into a crate of each size for people looking for just one.(need picture here of eight crates)

Last, get someone to check the Don't Know Pile and show you where to put the scrap, put the sorted crates back on the shelf and the empty bucket in its spot, straighten up your area, and mark this task "Done". Thanks!


Left pedal threads slope up to the left.

Right pedal threads slope up to the right.
