I am perplexed to the point of this.
I found a gem Schwinn and I am just now beginning to restore it. But as I took off the front wheel with its QR, I notice that it was also attached to the fork by way of a brace in between the hub bolts. The braces actually screw into the fork?
Is this an original part and what's the point? Is it a theft deterrent? I can't imagine having to always carry around a phillips screw driver long enough to get at these things in case of a flat. I'd just as soon go buy a Pinhead Wheel Lock.
