Fat guy on a skinny bike?? (vintage Columbus SP tubing)

I've posted this over in the Clydesdale forum, but I'm hoping some of the vintage guys in this forum will chime in over there. Thanks.

when I started cycling I weighed about that much. Never had a problem with the frame, I was told that if the bike was going to fail it was going to be the wheels.

Posted in your other thread but just in case:
As long as you're riding on 32+ spoke wheels, you shouldn't have any problems on a steel frame.

Posted in your other thread, too. You said you have some popped out spokes: these are failed and unsafe wheels for any rider weight, and the rims need to be replaced with good new ones. This needs to be done by a good wheelbuilder. Normal road rims with 28 mm tires or rims a littlw wider than normal should be good for you, in normal riding. No jumping!

Columbus SP is the variety of Columbus SL for big guys, powerful guys or bikes with big (58 cm+) frames, so no reason to be afraid. As others have said, the frame is the least of your worries - in the plane that is most affected by your weight the structure is the strongest. There are a lot of guys out here that weigh a bit more and they get good miles out of their vintage frames. The wheels are however more a cause of concern. Try to use wheels with high spoke counts (like 36) and with strong rims. And have them trued real good by a professional, because once a wheel is out of true it goes bad exponentially faster.

This sounds just like hard drives, in that once you've got a few bad sectors, it just a matter of time (short time) before it fails and you can no longer retrieve any data from it.

I had a World Sport back in the day, and I heeded the dealer's warning when I bought it. "No curb jumping", et al. The only thing I'd even attempt to jump now would be dog turds and SUVs, and not necessarily in that order.
