    Rust Inside my Steel Frame

    I bought my Fuji track bike in September and I swear I have not ridden it in wet weather, but I was cleaning the bike earlier this week and took off the seat tube.

    There's already rust inside the seat tube, where it is welded to the bottom bracket.

    Do I need to worry about this?

    I'm planning in getting it treated with Framesaver, but don't have the time now (I have to take it to a bike shop because there's nowhere to do it in my apartment).

    "There's already rust inside the seat tube, where it is welded to the bottom bracket."

    Rust where welds meet is both common and normal due to the
    burning off of compounds during the welding process. If it'll
    make you feel better pour a bit of oil in the tube but I
    wouldn't worry to much about it.

    I agree; unless the rust is extensive, it should not cause you any problems.

    It's not a big deal but the Framesaver will give you some more peace of mind.

    Oh, a little rust never hurt anyone. It's unusual to have so much rust that it actually gets anywhere close to affecting the structural integrity of your frame. Just keep the paint intact and the frame dry and it will outlast you. FrameSaver or similar products definitely don't hurt. I hear these products are messy, and you should probably strip the frame down first before applying. Gives you an excuse to give it a good cleaning anyway.

    I've seen some beautiful frames ruined by internal rust.

    You should clean and protect inside every steel frame.

    You need to strip it down completely...... every nut & bolt! Then clean it inside with degreaser and wash it out thoroughly with plenty of water. Blow it out with air, specially in the tiny vent holes. Put it out in the sun for a couple of days (or if you are in a cool damp climate, put it in beside the heater at least overnight. Get it nice and warm to evaporate all moisture out.
    Get some lanoline rust proofer ( thinned wool fat) in a spray can and some in a paint can.
    Use the spray to liberally coat inside the seat tube, down bar and chain stays from inside the BB.
    Then using the liquid and a syringe, fill the top tube & drain it back to the can, fill the seat stays & drain back to the can, fill the bridges & drain, fill the fork blades & drain.

    Leave the frame to drain & drip and let the thinner dry out of the lanoline for a couple of days.

    Re-assemble the bike, and enjoy it for years & years, even riding in the rain will not hurt it.

    You can use fish oil instead of lanoline, but its not as good 'cos it dries to a skin, which rust can crawl under. Lanoline never dries, so it has no membrane strength, so rust cannot crawl under it.
    I don't know what the "frame saver" stuff is but it cannot be better than lanoline (maybe its as good) but any treatment is only as good as the thoroughness of the person doing it.
    Do it yourself, and you know its done right.

    Everyone with a steel frame should do this.

    I use WD40 to rustproof inside my frame. It gets everywhere and leaves a thin film of protector. The bike lived outside in a damp coastal town for 2 years and the inside of the seat-tube is still shiny. You can squirt WD40 into every vent hole.
    I dont think its a good idea if you have a traditional bottom bracket or one with replaceable cartidge bearings, but for Shimano cartridge systems it doesnt do any harm.
    I'm not sure if this is compatable with a framesaver treatment, but it seems to work just as well.

    My LBS wants to charge me $65 to do strip the bike down, apply "framesaver", and put my track bike back together...
    Worth it or should I try to do this myself? The most I have done so far is basic tune up on my road bike...

    To do it right,you have to pull the fork, and BB.It's also messy.

    Alot more messy then you would think... if you'r not broke then go to the LBS. IF you can trust them to put everything back properly. I would have my LBS do it.

    Or just drill a drain hole in the underside of the BB shell, squirt in some wd-40, and some down the seattube and quit worrying about it.

    Or you could do this and still worry ! I still reckon you should get messy, do it yourself properly, and sleep peacefully for the rest of your life!
