The Universal Bike Bearing Press is a great multipurpose tool for pressing bearings into bike wheel hubs and bottom brackets alike, covering everything from 12mm to 36mm diameter. These are well made, easy to use, and very effective, while being exceptionally affordable compared to the much more expensive "professional" grade sets. IMHO they are very comparable and capable, and a lot less expensive. And they work better than the cheap stuff folks try to make up from a bunch of parts from your nearby hardware store. An elegant device indeed.
