Even when you get dings in the paint, rust never gets too far because the surface has a chance to dry, so you don’t really even need to touch up scratches (of course, if you leave it outside under a tarp, it’s going to rust more than if you get it out and ride it). The outside of your frame is covered with a tough coat of paint. Also note that it only works on single-position mounting plates.Īt this point you can install all the parts if you so choose, but we recommend also protecting the inside of the tubes.Īpply Rust Inhibitor To The Insides Of The Tubes Most disc calipers these days have a lot of adjustability built into them, so facing is not really necessary. Facing the tabs provides a flat, even, straight surface to attach the caliper to. You may want to face your disc caliper mounting tabs too. Do the same thing with the derailleur hanger threads if your frame has a hanger. If there is excess paint on the threads, have them chased with a BB thread cutter. This usually results in an acceptable result, saving you money, but we still recommend having it done the proper way to ensure longest life from your components. Since Surly frames are faced prior to painting, it is possible to shave the paint off the head tube and BB shell ends with a carpet knife blade. All that really needs to be done, however, is the facing itself. Reaming is probably not harmful if the tools are sharp and of high quality, and if performed by someone with experience. Reaming is not generally necessary on good quality frames (such as ours), on which manufacturing tolerances are kept in check, unless there is excess paint inside the headtube. This means that not only do they shave the tube ends, they also mill the inner circumference of the headtube. Many headtube facing tools are also reamers. Again, this work should be done by someone who knows exactly what they're doing. This can be especially harmful to outboard-style bottom bracket bearings, which require proper width spacing to adjust properly. Done wrong, facing can remove too much material (metal that used to be your BB shell or head tube). On Surly frames it is usually not necessary to remove much (if any) metal, just the paint. Facing removes excess paint and metal, making the tube end surfaces parallel, thereby ensuring that all the pieces of the headset or BB square up and operate smoothly without 'hotspots' of excess pressure and friction which can ruin bearings prematurely. It’s a good idea to face the head tube, fork crown, and bottom bracket shell (where the crank bearings fit). The first thing that should be done to all frames, not just ours, is to have it prepped by a competent professional. With a bit of care, it'll ride the same in 20 or 30 years as it does now. Maybe your new Surly is your first steel frame and you’re discovering what we’ve been preaching for years: steel has a special ride, snappy, comfy.
