adding water bottle bosses w/out brazing

[Jpinkowish]

Can one add water bottle bosses to a steel seat tube w/out welding? Remove small amount of paint,
drill pilot holes, and use JB Weld or similar to attach braze on bosses?

Or is this a total dweeb hack?

Successes? Failures? Tips?

riv-nut or nutsert tool can install a threaded aluminum rivet that is 5x.8mm threading on the
inside. Many bike shops have them - try shops that sell lots of aluminum bikes like a Specialized,
Cannondale, Klein or Trek dealer.

Why bother? Your LBS should be able to supply you with a plastic attachment to let you fit any extra
water bottle for a couple of pounds. Uses two plastic bands to hold any normal water bottle cage on
the frame, simple and easy to put on, simple and easy to remove. Durable I used one on a 1700+ mile
road and trail ride last year with no problems. Pic at:

If you are so adventurous you're probably better of using reasonable sized selftapping screws
instead of big 7mm holes. BTW Whats wrong with hoseclamps?

That will probably work, but unless the seat post is steel and heavy, I'd hesitate to drill it
because of the possibility of reducing it's strength.

My LBS has some old adapters that go on the seat post and have the right size tapped hole in it for
the bottle cage. You just slide them on, put the cage on 'em, position 'em and tighten the bolts
that hold them in place.

I think those are made by Zefal. At least they used to make some.

I have the TwoFish velcro attached bottle cage and it meets my need.

A better approach would be RivNuts.

My preference is not drilling, not limiting myself to a single mounting point

A brand called Minoura makes adapters that fit on the handlebar, Litech and Tacx produce adapters
for the seat (not the seatpost), Tacx and Zéfal have clamps for frametubes.

Yes. I have done this on many steel and al bikes. Less stressing of the area than a rivnut. A
particularly nice adhesive is Devcon "Plastic Welder" Part # S220. -40 > +200 F 3500lb PSI 25ml 2
part pack. 4 min working time. About US $6.00 I have used this stuff to join just about everything,
except poly plastics. www.devcon.com

Note that my seat tube (you did mean seat tube, right?) is aluminum and light. It was drilled for a
Riv-Nut at the factory and has been performing satisfactorily for over ten years. The down tube was
similarly drilled. It hasn't failed either.

Do you realize that practically every diamond-frame bike sold in the last 15+ years or so has those
extra holes drilled in the seat tube for a second bottle cage?

Do RivNuts require special tools to install?

Where do you get them - hardware store?

A RivNut is similar to a pop rivet but instead of being drawn by a breakaway nail there is a
threaded center. That requires a threaded setting tool. You probably could use an SAE 10-32 threaded
RivNut ( the thread is very close to a metric m5x0.8 thread) from a hardware store, but I would
recommend a competent LBS who will have both the tool and the RivNuts in metric.
