Road Cycling “It is by riding a bicycle that you learn the contours of a country best, since you have to sweat up the hills and coast down them. Thus you remember them as they actually are, while in a motor car only a high hill impresses you, and you have no such accurate remembrance of country you have driven through as you gain by riding a bicycle.” -- Ernest Hemingway

Thanks!

I'm going with chain hanger for when you remove the wheel. Very handy and old school.

Ha! I ask that question a while back. I still haven't tried using it despite the number of times I taken my back wheel off.

It is indeed, a pin for hanging the chain when the rear wheel is removed. I have one on my '84 Pug and it comes in handy sometimes.

In order to hang the chain on it, shift the chain to the smallest cog. This is in any event, the preferred method for getting the wheel out of the dropout.

It keeps the chain from flopping around when the wheel is off.

It's really handy when transporting the bike in the car with the wheel off.

BITD, it was one of the features you'd check off while comparing bikes. "Two braze-on water bottle bosses, CHECK. Toe clips WITH straps, 700c wheels, CHECK. Pump peg, CHECK. Chain Hanger ...."
