Oh the perils of owning a 51 year old bike. On my commute this morning I noticed a rather impressive crack on my Mk2, just at the point that the seatpost meets the downtube. The metal has completely failed around one side of the joint. Needless to say this puts it out of action once again, but I wanted to know if anyone else on the forum has experienced a similar problem, and whether / how they got it fixed successfully. Any feedback / advice gratefully received.

Have a look at the ” tail pipe cut off” topic. My crack is still to be resolved, open to suggestions on repairing this.

are the diag struts for the rack removed? see the post as above

[Jon Mundy]

nope. all in place. have sent it to a frame builder to be repaired.

I repaired this crack, and all was well, however a new crack has appeared further up the seats-post, at the point where the crossbar intersects it. I’ve had frame builders tell me this is beyond repair. Is that the case or has anyone on here had a similar problem and found a way to fix it?
