    Preventing rust on custom steel?

    I've been looking at getting a custom steel bike, but worried about rust. Are there certain options I should look at that would minimize rust such as paint finish (powdercoat?), etc? I want something low maintenance, and Ti was suggested to me, but I just love the look and ride of steel so much better. Would appreciate any suggestions - TIA.

    There's always stainless steel like 953, XCr, and KVA MS2. My main ride is a 5 year old polished 953 Waterford, and it still looks brand new. I don't have to worry about paint scrapes or rust in spite of frequent rides in the rain, and it rides like steel (because it is).

    A number of builders at NAHBS last month (Sam Whittingham of Naked Bicycles and Design, Dave Anderson of Anderson Custom Bicycles, and Dave Wages of Ellis Cycles among others) showed stainless frames made with KVA.

    I'm not a builder, but I see a lot of older bikes at my shop and saw a few good posts on this before the framefo went down. This is an imaginary problem for most people. Oxidation is actually self limiting to a degree. It forms a barrier preventing deeper damage. For instance, I've got a spot where a local welder took off the paint on my Surly Steamroller to put on rear brake stops. I've been meaning to paint it for almost a year. In the meantime, it's just been bare chromo. I've ridden in the rain a few times, had it out tons... and there's only a bit of discoloration on the very surface. I'll paint it eventually, but it'd take a LONG time for it to be a real issue.

    Internal stuff in a large part depends on the care and construction of the bike. Make sure to use plenty of grease on your seat-post if you're going to spend a lot of time in the wet, it acts as a bit of a gasket to keep water from getting in that way. Ditto on water bottle bolts. Don't leave the bike out in the rain longer than necessary, give it a quick dry when you get it in. Some builders make a vent at the BB, so that water that sneaks in can get out again, that helps too.

    The most common case I've heard of really deep structural rust is when some paper or cloth gets left in the frame, either cleaning or by the builder. I heard one story of someone finding a rusted through seat-tube with an italian newspaper stuffed in it... that sort of thing holds liquid in contact with the tube and prevents quick drainage or evaporation.

    I'm not trying to say that stuff doesn't rust, just that if it was the pervasive problem that a lot of people worry it is, we wouldn't have all of those 70's era road bikes found in people's back yards still rolling around.

    If you're paranoid (or live by the water, or in another area with salty air or corrosive dust), use some frame-saver... most bike shops can order it. It's a rust-arresting and preventative spray that you can roll around in your frame to guard the inside. Some intelligent builders call even that level of preventative maintenance unnecessary. You can cover external scratches with clear nailpolish.

    Also, never bring a bike you don't want to die to burning-man.

    @Scooper: How does stainless steel ride in comparison to something like Columbus steel, Reynolds 753, or Tange? Is it stiffer?

    @VRB: Thanks for the input, and you're right, I'm probably being overly paranoid, but it's just one less thing I want to have to worry about when riding if possible. I don't intend to ride in downpours or anything, but sometimes you can't avoid getting wet (random shower, puddles, etc).

    Nope; the ride isn't any different. All steels have essentially the same Young's Modulus. The 953 tubes have thinner walls (as thin as 0.3mm), but because the tubes are OS, the frame stiffness is similar to my 531 Paramount with standard diameter tubes. The stainless bike is several pounds lighter than the Paramount, so it accelerates faster and climbs better than the Paramount.

    Though, with such a shiny bike you do have to worry about giant birds flying away with it to build their nests ;-)

    I find that bikes that are neglected have a far greater chance of rusting. Periodic breaking down, cleaning and well lubed reassembly will off set a lot of bad exposure. Andy.

    It's not a real problem with 4130 mine spent 10 years in Oregon riding every day. In general higher strength tubes corrode faster than lower strength ones. I've seen rusty 17-4 PH caused by galvanic corrosion.

    It is an imaginary problem for the most part, unless you live in Atlantis, or store the bike in the open and it rains a lot. I would not let it determine my materials choice.

    I've been riding a custom steel frame since 1994 with nary a problem, & I've ridden & raced it in the rain occasionally. I got some nicks in the paint & touched those up with primer until I got around to having the frame powder-coated, & I've kept the seatpost & cage bolts greased, & otherwise I haven't worried about it.

    For extra credit: It's a Clark Kent; who remembers them?
