Suggest merging ISIS drive article into this, and writing sections on various BB designs (BMX 3pc splines, cottered, ST, Octalink etc.) rather than writing a separate stub for each. -- Lordandmaker 13:46, 14 March 2006 (UTC)

Sounds great! Cycling-related articles could use a fair bit of merging in general other places as well. --Christopherlin 17:33, 14 March 2006 (UTC)

[edit] Shell

Perhaps someone can supply a more precise definition of "shell" and its relation with the rest of the frame. Jim.henderson 23:39, 6 June 2007 (UTC)

[edit] Comments about Campy vs Shimano, FSA, and others

"This design is perhaps the first to acknowledge the fact that the new outboard bearing designs do not require a press-on fit, as the old square taper and splined bottom brackets did. Whereas the Shimano, FSA, and other designs require that the inner face of the cranksets press against the outboard bearings, a situation that introduces a significant amount of rolling resistance (and which thus creates a market for expensive ceramic bearings), Campy's Hirth joint is machined to restrict the compression of the bearings to a controlled tolerance. Characteristically, Campgnolo's marketing department has chosen not to emphasize the fact that the Italian company has introduced the first integrated bottom bracket system to spin nearly as well as the non-integrated versions did."

  1. "is perhaps the first" not very encyclopedic.
  2. what Shimano, FSA and other designs require and how Campy's is machined needs a reference.
  3. Whether Campgnolo's marketing department has acted characteristically isn't really germane to an article on bottom brackets.

[edit] This article is rather repetitive.

The information is good, but requires sorting as several sections are supplied in triplicate! Donebythesecondlaw (talk) 15:47, 7 June 2008 (UTC)
