Question about freewheels, cogs and flip flop hubs

[Trek420]

(Mind you, I didn't build the ss/fixie flip-flop sitting here in my living room; but I've always assumed the freewheel mechanism was the "flip" part of the "flip-flop" hub. Which makes it possible to switch from ss to fixie so simply.

Yes it does. But I've been instructed by Chris at Robinson Wheelworks (hi Chirs!) who built the bike not to flip the flip flop.

Mixte's have a lower center of gravity/bottom bracket making it perilous. If you turn your fixie mixte and just happen to have the inside crank heading down at the apex of the turn So don't flip the flip flop.

[hijack] That's not exclusive to mixtes or fixies. A lot of factors play into your maximum lean angle with the inside pedal down ... BB height is one, but wheelbase and crankarm length are in there too, and so is the width of your pedal and even your foot. Once you're down there, it doesn't matter whether your hub freewheels or not, because bici pedals don't fold up the way motorcycle footpegs do.

This is how I wound up five feet in the air, upside down and jackknifed front-to-back, heading for the ground head first, 24 years ago last month ... Thank you Kiwi helmet.

The lesson is, inside pedal UP. That's the only way you can get your OUTSIDE pedal down anyway, to use your outside leg as a shock absorber to keep traction in your rear tire.
