Hi All,
   I picked up an old Wienman concave rim from a bike shop today, 36 hole of course. The shop owner didn't know what it was, except that it was "an old 36". I noticed that the rim has virtually no "hook" to it and in the dim recesses of my middle aged brain, I seem to remember that there may be a problem with mounting certain tires on non hooked rims, but I can't quite remember specifics. Does this ring a bell for anyone? I plan to build it up with 3x spoke patern on a flip flop hub for a fixer and run 25 or 28 mm wire bead tires. Thanks, Karl "2070 ft of climbing on the PX10 today and still well below the snow line" Eicher
