Who needs a fancy QR stem.
I have been thinking about quick release stems to make the dropbar setup more compact when folded. It occurred to me that a QR skewer could be fitted to standard bar clap. Here it is, a cut down seat clamp and alloy spacer turned to fit in the flat where the screw is located. The other screw is held in place with thread lock to prevent it working loose.

Here is the bar setup without the handle bars being rotated.
And bars rotated with the use of the QR.
