Max was talking about doing something with the stay, which I was keen for, but now I'm worried about the seat tube. Do you think it's repairable? I don't have the cash-monies for a new polo frame right now, so anything to keep it going for another month or so would be great.
Cut off the broken bit. Cut new slot. Move clamp down. (and/or get that double clamp we discussed http://www.chainreactioncycles.com/Models.aspx?ModelID=8213 for extra support) Come do it at my house if you want?
