rust prevention

[redwood]

I'm getting a new redline monocog (Chromoly) for winter riding. Anybody have experience or opinions on using those spray in frame sealers to prevent rust inside the frames? And how about taping over those little welding holes on the chainstays back by the hub?

First off I would definatley not tape the welding holes. They originally worked for welding but now they allow air flow through the bike. Water is going to get inside your bike no matter how sealed you make it. A lot of water goes up through your fork crown and down your seattube.

I would pick up a can of JP Weigle Frame Saver. It has good directions so mainly follow those. Do one tube at a time making sure to twist your frame around to allow the stuff to coat the entire inside.

I don’t know how well this would work but when we weld sheet metal we use a galvanization spray to protect the weld area. Galvanized sheet metal is steel with a zinc coating then covered by galvanization. When you solder galvanized metal you use a 50/50 lead/tin mixture and its kind of like soldering copper pipes except you don't use flux. You brush muriatic acid on the weld area and it eats away the galvanization and you are really soldering to the zinc coating. Since the acid eats the galvanization away and the heat from the acetylene torch combined with the acid eats the zinc where there is no solder you have to spray the galvanization back on or the raw steel will rust with days after the first rain. It's not the prettiest stuff (dull gray kind of like primer) but it does work. I think you can pick it up at Home depot in the paint isle.

I would recommend getting some JP Weigle Framesaver. Spray it liberally inside the vent holes, down the seat-tube, in the H2O bottle holes... shake, turn, shake, spray, roll, hang to dry.

It stinks like crazy, but dries to a wax-like coating that is excellent on preventing rust. You should be able to find it at your local bike shop.

I've been told (by a semi reliable source) that 'frame savers' are little more than a thicker version of WD-40. Any truth????

Navel jelly is what the navy smears all over everything metal on a ship that's being mothballed. You may have to cut it with something that would allow it to spread uniformly, but a product like that should certainly do the job for a bicycle.

Framesaver is overpriced linseed oil with a propellant- sticks around longer than T9 or triflow, but the effect is the same. T9 (and to a lesser extent, Triflow) has amazing capillary action, so I think it does a great job for rustproofing the inside of frames. In theory, at least, linseed oil takes a few weeks to fully cure, but your mileage may vary- my '79 Paramount has JP Wiegle inside, my Surly SS winter ride is carrying a can of evaporated Triflow around between the frame tubes and the assorted steel hardware and insides of fenders (so snow doesn't stick)- go figure. Framesaver- $15/can, Triflow- come into Freewheel when I'm wrenching and its $0 for anyone winter riding on a steel single ;)

triflow - that's goooood

Hey Joshua... are you by chance one of the other few riders to the "Trek University" event in Bloomington?

For everyone else, you might find this as funny as I do...

Trek held what they called Trek University to teach all about Trek products (Bontrager, Fisher, Lemond, and Klein) at the Holiday Inn in Bloomington. On the day that I went, there were maybe 100 bike shop people there from area dealers. Scott and I from County Cycles were 2 of only 7 people who rode their bikes to the event. Six out of the seven bikes were singlespeeds, and Scott and I were the only ones on Trek products, both converted old steel singlespeeds. Further irony was that the day was about 40 degrees and the rep from Shimano talked about the people who rode that day riding in "inclement weather!" Any they call themselves bike people:D

... well, then again maybe you don't think that's funny. Now, back to the regularly scheduled programming.

Another cheap way to go is to just pour a whole bunch of motor oil into the frame and let it drip out through all of the holes. Catch what drips out and pour it back into your bottle. You can recycle what you don't want to keep by bringing it to any oilchange location. One quart will go a loooong way.

I just consulted "Zinn and the Art of Mountain Bike Repair". Not the brand new edition but the previous one from 2000 or so. Zinn recomends periodicly spraying frame saver OR WD-40 inside the frame. So another weighty vote that frame saver isn't the only product to keep rust out of the frame.

[Rocky Mountain]

If it means anything, I paid the inflated price of $10 for specific frame saver spray and have had good success since. Now WD-40 cost what approx. $2 so who is going to sweet this $8 cost difference when the feedback majority has used a specific framesave spray with positive results. Plus WD as the acronym states is a Water Displacement solvent and not that effective of an oil.

Nope, Kampa never met up with us that day. He didn't look inside Freewheel where everyone was meeting up and spent his day curled up with a warm Muffin instead. That day was 70% beautiful to ride in, don't know what kept the rest of the shops off their bikes.

Putting anything inside the frame will be better than nothing at all and the mere act of pulling all the parts off your frame at the begining and end of every winter will go a long way towards making your parts last longer. I spray some non-stick cooking stuff on the underside of the fenders and the downtube/BB junction. Those are the places where snow clumps up and will leave a big mess if it falls off inside your house.

Hey Tyler,

Just want to say welcome to the discussion forums. Sounds like you work at Freewheel. Great shop.

There's a lot of good discussions on the site and a ton of good info. I'm sure you've got lots of tips to share as well, as you just did.

Happy ridin'
