Yeah, really. I think I just can't use this one.
The struts for connecting to the upper part are pushed in to their shortest point. Can't quite figure it out. I bought a new one, but it turned out to be for 23" frames or smaller, so it went onto the wife's mixte. It's a brake-bolt mount.
This one is temp, I guess, until I buy another. It IS quite annoying, tho.
