As I have to store my bike indoors to avoid it being half-inched off the mean streets of Islington in central London, I was keen to find a way of turning the handlebars sideways to reduce the space it takes up.
I was looking for a QR with a shoulder, so that the lever would clear the stem when closed. These Thorn QRs do the job, though a specific product would be a bit neater. Strangely, nobody else in the world seems to have bike storage problems, because a quick-release ahead stem is not only unavailable, but it seems nobody has every thought of it before.
Anyway, I used two of these Thorn quick releases to convert my standard ahead stem to a quick-release system. This now allows me to turn the handlebars sideways so that the bike takes up much less space. I've been using it for a fortnight now without problems. Result!
