Structural integrity

[BalkanExpress]

I have seen a Raleigh professional frame on a well known Dutch website.

The fly in the ointment appears to be three 3mm holes drilled in the frame one in the seat tube, one in the rear stay and one somewhere else (thanks Google). The pictures are not very clear and I should probably leave well alone...but if the holes are not structuraly significant and everyone else is put off bidding, it could be a winner...or a death trap.

Advice and sarcasm are welcome.

1975 Carlton in blue mink colour dressed as a Raleigh for USA export. Not sure about the holes but I would love that

Hit it with a hammer, if it doesn’t fall apart, it’s a winner.

If I do and it turns out to be a bit large, you will be the first to hear

Well the frame has survived so far ! The hole doesn't look recent .

You can give us an up to date day by day info as to what effect such holes have on a frame !

Looking at the photos it doesn't appear to be a major issue.

The apertures in the BB intrigue me, I'm trying to make my mind up whether they keep it drier or make it wetter.

They wouldn't be of much use if there was an oiler on top .

I would have thought that if you were to ride through a puddle the water would shoot directly into it and end up in the chain stays !

 

[Illaveago]

Thinking of hole wise. Front forks have holes top and bottom in them as do rear seat stays, chain stays have holes at the back underneath .

They might make a whistling noise when ridden .

Where is the rear fork hole?

Generally small holes don't affect proof strength that much (before the frame bends in a crash) as the stresses will re-distribute following local yielding. However fatigue strength is badly affected. Fatigue loads will be highest at the ends of the tubes or mid-span. Not that concerned about what I can see so far.

At the bottom near the rear dropouts .

There's not much left of the underside of the b/b and if that doesn't concern you then why worry about a few little holes in other tubes ? Anyway it might make a pleasant whistling sound as you ride

twas trendy to cut holes in BB's (see my avatar). The "CC" = Carlton Cycles cut into the BB of the OP's linked frame was also part of branding. Other makers used an ace of spades etc. We used a protective sleeve over the BB holes, you can see mine painted black.
