Both frames had cracking in the lugs/tubes from the clamps being tightened too much with the stock 27.2 in there. One I had repaired and later sold, the other I got used and fitted a shim right away so the cracks haven't spread far enough to weaken the clamps.

Would you like the serial no. of the second of my frames? I still have it hanging in the garage awaiting better days.
