Carradice Quick Release

Here's my new version

The first version worked pretty well. It did have a few problems:

It used parts from the now obsolete cyclo bag hoops.

The clamps tended to rotate on the saddle when the clip rings were closed.

The clamps tended to slide down the saddle with heavy loads (>15 lbs).

My second version basically attaches the same fittings to an aluminum bar with pop rivits. The bar is then clamped to the saddle rails in a way inspired by the Carradice Saddlebag Clamp.

Although heavier and more complecated to make, it seems to overcome all of the problems with my first design. I have them on a couple of bikes and can move the bag easily between bikes and take it off the bike to go shopping.

This design fits both Brooks Pro and a Swift. I'll try to post a drawing soon.

I don't know how it will hold up, but I think it will do better than the plastic quick releases held on with ty-wraps that I was using.

Some smaller pins would be nice, and they need some attachment so you don't loose them, but it looks like it should work. My test ride was with a "dummy load" of a 5 lb. bag of flour. It did fine.
