Holes in frame tubes are on the list of Ideas That Don't make Sense:
- fluted seatposts
- bottom bracket cutouts
- crimped frame tubes
- curved frame tubes
- L-shaped cranks,
- lever-action drive
- etc etc
The manufacturers count on buyers
- not knowing basic physics
- having disposable income
- believing the pimply-faced youth who's trying to boost his commission
