Screw bosses on underside of down tube?

[Pale Rider]

As Profpointy said they are for an extra bottle cage although I wouldn't recommend drinking out of the bottle mounted under the tube as they do get really dusty/dirty down there. Advise is to use to top up the other bottles.

Sound advice.

A mate of mine picked up a nasty gastric infection from drinking from an under-tube bottle.

Most likely cause was a tiny amount of animal faeces/urine which had been thrown onto the top of the bottle.

I have them on my thorn, they're for a 2nd or 3rd bottle cage.

Ditto. The same on my Ridgeback Panorama. Probably very useful on a tour or a major ride in hot weather, but beware: Need to remove the said third bottle cage before the bike will fit on a car roof-mounted bike rack. For that reason I have never used mine.

Thanks,chaps, makes perfect sense now.

I quite like my Boss, he seems like a decent person, so...no thanks I shall leave him in his office today.

Vodka? Absinthe?

NOoooo, that goes in the middle of the sleeping bag, it would be a disaster if the 'essential supplies' were damaged.

As already been said best used for fuel bottles.

Geoffrey Butler sells a bottle-sized screw-top container for tools, etc., that fits perfectly in the third cage. I keep two tubes in mine.

Fuel Bottle, or extra water store. I wished I'd fitted mine for LEL it was that hot.

Just to join in with the tourer pics

I've known quite a few I'd have happily screwed to my down tube.

I am my own boss, so I will not be screwing myself today...but other fekkers are available and can be screwed...just to keep some balance....

I'm always surprised more people don't get ill after drinking from bottles without flip caps, especially in winter, especially if you don't have mudguards.

A certain crisp manufacturer whose label sounds like "dringles" also make a tube shaped container that perfectly fits the average bottle cage and is great for carrying tools in. There are other crisp manufacturers.....

Good place for the di2 battery though

Their tubes are also perfect for making a carbide cannon. Tape two together, bottom one is the combustion chamber and top one is the barrel. Fired a tennis ball a couple of hundred yards, but did end up deaf for the rest of the day when I got a detonating mixture, rather than the more desirable burning fast mixture. Great fun !
