Kinesis, and Maxway make the bulk of the worlds frames (as specialized, Giant, Trek, Bianci, Surly, and %90 of other bikes out there) , and there are probably like six or seven parts mfgs that make up an equally huge part of the OEM spec. Formula hubs are definitely one of the bigger bearing/hub mfgs making parts for specialized, bontrager, WTB, Velocity, and a huge list of other companies.
Sugino is actually a big rebadger too. Their RD cranks are rebadged OEM for a lot of different companies.
