EvaluatingHubs

Print

Evaluating hubs requires that you already know how to evaluate and adjust hub bearings. If you don't, you can ask a key volunteer or staff member to teach you, but it's something you learn through hands on practice. Once you know how, the process is very simple: evaluating the bearings is the most important part.

Keeps axle nuts on, but remove any quick release skewers — put their springs and nuts back on them, and put them in the grey drawers by the grinder in the parts aisle, sorted front (short) and rear (long). (put extra long in the back of each drawer)

Flange damage

If the flange is bent or any of the flange holes are ripped or badly distorted, the hub should be kept for its parts if it has a crate and its bearings are in good shape.

Evaluating the bearings

If you feel that the bearings will adjust well enough to make the hub worth being built into a wheel — or, more likely, worth scavenging parts from — it is worth keeping. Even if the hub body is not useful, if the cones are in good shape the hub is worth keeping - the cones might be usable as replacements, and they're easier to identify if they are still in the hub, which is easier to find a match from than a coffee-can full of cones.

Bent axles

Hubs with bent axles (hold the hub body and spin one end of the axle while looking for wobble at the other end) can also be kept for spare parts — write "bent" on the hub with a sharpie.

Hubs to scrap

Pretty much any hub with a steel body is not worth putting into a crate to keep (but watch out for antiques) — it won't be used for spare parts, and it won't be built into a wheel — but it may be collectible, or used for art (see below).

Hubs are sorted into crates by front and rear, quick release or nutted, high flange or low flange; and rears by freewheel (threaded body) or cassette (further sorted by number of speeds?). (need pre-sort piles and labeled crates to do this right)

After you have sorted those you think are good into the crates, put any all-steel hubs in the steel scrap (after removing any good axle nuts), and aluminum hubs — and any all-steel ones that look interesting — in the "Art parts" bin. You can put any hubs you are not sure of back into the bottom of the bucket with a round piece of cardboard almost as big as the bucket I.D. on top of them with "don't know" printed on both sides of it.
