rust inside the frame how to treat it
I have a bike that has been sitting in the outdoors for 3 years. I
bought it from the guy-a ganwell pro. Hand made(?) japanese bike, all shimano105 parts. there was some water that drained out of the small holes in the frame is there some way to treat the inside of the tubing to prevent or slow down the rusting? I heard on this group of a spray that you fill up the insides with. the frame is steel. thank you direct email welcomed |

rust inside the frame how to treat it
What KIND of steel is it?
CrMo - seems to me - is fairly rust resistant. Ridden hard and put away wet for a decade, my last CrMo frame had LIGHT surface rust inside the untreated tubes. It never "flaked" or got deep/structural. If you're really concerned, 1st, remove any rust that's in there. Try a long wire brush - tubular shaped on a long handle - designed for cleaning inside pipes. Once the rust is gone, you can do one of two things: use a moisture barrier or a catylist that reacts with the metal to make it inert. I went the vapour barrier route - boiled linseed oil. Spray with one of those pump spray bottles like Windex comes in, coat the inside of all tubes and DRAIN the excess out. (trust me - you don't want this stuff dripping out onto your drive train - it turns to brick-parmesan) Works for me. Biodegradable, smells nice, non-toxic. Some people recommend WD40 and such oils. I don't like these as moisture barriers because they never dry or if they do, they seem to lose their protective properties. WD40 specifically was designed to displace water and be reapplied repeatedly. (or as a temporary lube) Dried linseed oil, as I say, is like a brick of parmesan cheese - very hard and plastic-like - and only needs one application. Good luck. I'm sure you'll get a lot of other replies. Chris "Alan Smollen" wrote in message ... I have a bike that has been sitting in the outdoors for 3 years. I bought it from the guy-a ganwell pro.

rust inside the frame how to treat it
well here we are again. there's a book hear. follow up to Frank. ima
gonna look over the archives to see what distills for search terms. linseed is your first shot. take the bike apart for new bearings and fresh grease. how one sprays the tubes a without fouling the BB grease ??. place frame in hot sun for 3-4 hours. rotate frame positions so all moisture boils up and out. thin linseed a bit. cap tube ends with rags screwed in tight. pour in some linseed. rotate frame. dance with frame. hold frame overhead. hot sun. thinned linseed flows over the tube's insides several times. the thinner's oil content will allow the linseed to dry slowly. linseed tends to cut off the flow of water and O2 into any rust. rust then hardens underthe linseed and the rate of conversion from Fe to the FeO's slows to wqithin your ride lifetime. if you decide the bike is a gem you may then take it to a pro in more or less one piece the above implies- a. you have the tools, and 2. are a capable bike mechanic. or you will soon be one. see Parks' mechanics site and search world cat for a barnetts manual near you. see sheldon brown!! harris cyclery |

I heard on this group of a spray that you fill up the insides with. The frame is steel. The way these post come up with some regularity, I suspect they could be "paid political advertisements" for non-steel frames. Rust inside frames has not been a problem over 100 years of steel frames. The only failures of note were from leaving newspaper stuffing inside a frame after painting or having a large opening at the seat post with no drain at the bottom bracket. There are plenty of ancient steel frames that have spent a lifetime in out door bicycle racks and serving well. On the other hand, this might be a "no loose ends" fetish. Jobst Brandt |

"The way these post come up with some regularity, I suspect"
Yup, always suspect. Meglomania as well: what his name-topper right? via Sony. IAMINCONTROLOFBIKETECH!yaaaahhhh! Rust inside frames has not been a problem over 100 years of steel frames-but on this tell Curtis and Scott, possibly BMW. the real deal here is menatl health. rebuild the bike and with any experience under your TT-the tube's insides nag at you-linseed seams to be the simple answer. how can the rebuilder ig nore what's left? or what isn't left? getting a good look at the top tube continues as a problem area. this reminds of NASA's new boom. boom boom ood thinking . I'll wait until I trip over an ex merxck in the boat house before going to the strippers. |

You don't fill the frame with it. Just let it coat everything. Distruction of a frame by rust is extremely rare, but it does occasionally happen. - ----------------------------------------------- Jim Adney Madison, WI 53711 USA ----------------------------------------------- |

You don't fill the frame with it. Just let it coat everything. Destruction of a frame by rust is extremely rare, but it does occasionally happen. To test the value of this advice, I suggest you take a clean piece of steel, for instance a tinned can with the tin steel wooled off, an spray some LPS-3 or WD-40 on it before laying it out in the morning dew for a few days. These lubricants do not displace water but rather emulsify with it. The inside of a frame, as I mentioned, is not at hazard from moisture unless you work at it. WD-40 as Gore-tex are religious icons without merit. They live entirely on faith. Let's tie and solder spokes again as the ancients did religiously... without merit. Also beware, smooth tread bicycle tires will aquaplane and cause crashes on wet roads... and many more. Jobst Brandt |
