discovered this crack on my ron kitching frame today. from previous owner. worried about it. i was going to install one of these on it when i realized it didnt fit, because the holes on the clamp are kind of ovalized. and i noticed the crack. could i just use a washer and it wont get bigger? why wont a regular bolt fit through? do i need to get a mallet out? eeeek. this bike was supposed to be a cheap quick build and rode to work for the next few years. this crack bugs me. and i HATE when my saddle moves around. it says "72" on the seat lug, assuming it requires a 27.2 seatpost, not sure if thats whats in there now, it came with the bike. along with a quick release that was too long and missing a part.
