Raised bottle cage bosses - why?

[KondratievsBike]

They look like the same as the stubs the down tube shifters fit to. Maybe builder was hung over and put them in the wrong place?

Serious guess now though. With those you wouldn't need to drill the tube, just braze them to the outside. Could save weakening a thin steel tube?

This makes sense to me as it has in fact avoided drilling the tube…

Strava says otherwise

Pah, what does Stavros know?

You would still need to clearance drill the tube for the bolt to go through
couldn't have a blind hole as someone would strip the thread if they fitted a bolt that was too long

So true.

Weirdly, this isn’t drilled and the bolt stops at the end of the boss. And that’s on a Dave Yates/Joe Waugh.

Some helpful answers on here though- thanks gurus.

water ingress. it stops the water running down the frame from your oversized water bottle from getting in the tube.

Or something much *much* worse when I get peeing downhill wrong

Not that I have the (bike) handling skills…

as my wife has pointed out more than once, I don't have the cock handling skills either.

a good wife should do all the handling

given the current duration of our marriage (ten years this year, no idea how she's coped) I'm not sure there will be any handling going forwards.
