Re: Bottom Bracket frame failure

Quoted message said:

I just bought a vintage Torpado Superlight frame from about 1985.
This frame is made of Columbus SLX tubing and was their top of the line

frame from that time. The frame is in very nice condition with no rust
and a clean bottom bracket shell. The bottom bracket shell is an
english threaded Cinelli. Torpado cut a decorative "T" in the bottom
bracket shell that measures about 2cm X 2cm. When my LBS professional
looked the frame over, he was critical of the cutout. He told me that
Torpado went out of business because of bottom bracket frame failures.
He felt that the cutout in the bottom of the shell might cause failure
if standing on the pedals. Does anyone have any experience with this
issue? Especially with Torpadoes? Another employee felt that this issue

diminished with the use of a modern cartridge bottom bracket. Any
opinions from the group would be appreciated. Thanks in advance.

Italian (and other) builders have been carving their initials in the bottom
bracket shell for decades without problem. I doubt that the "T" is more
dangerous to the integrity of the bike than any other letter or playing card
suit.
