As to phil wood etc. you can get a significantly better price/quality ratio with other manufacturers if you prefer cartridge bearings.
Phil Wood, Chris King, Paul and White Industries to name a few are in business because of there quality. The Phil wood hubs on my 28 year old tandem are still in perfect running condition. The tandem came with some of those significantly better price/quality ratio sealed bearing hubs. The rear axle bent the first week. The company replaced it and it bent. I ordered Phil Wood hubs and no problems since. My custom touring bicycle came with significantly better price/quality ratio disk brake calipers. They and two other caliper sets did not make me happy. I purchased Paul Klampers and they do what brakes are supposed to do.
