Profile Evolution Bottom Bracket

  • Available from 2003 to 2005
  • Prototype first pictured in BMX Plus! magazine (Oct. 2002, p. 12)
  • For American sized bottom bracket tubes only
  • Discontinued from production due to the increased popularity of European (Euro) and Mid bottom brackets
  • A male-female threaded cup design - secures itself to the outside edges of the frame's bottom bracket shell
  • Self-installing and self-removing by either tightening or loosening the respective halves to each other
  • Essentially a single unit when installed
  • Perfect bearing alignment is achieved
  • Installation requires the use of Profile's proprietary Evolution wrenches - sold separately (in pairs)
  • As easy to install/remove as a Euro bottom bracket
  • The three-eyed alien logo that was machined into the middle of some of the Evolution bottom brackets was taken from the 2001 American science fiction comedy film "Evolution"
  • Two version available - Race Evolution and SS Evolution
  • Race Evolution: for 19mm (3/4") spindles (19mm ID x 1.625" OD x 0.438" W bearings)
  • SS Evolution: for 22mm (7/8") spindles (22mm ID x 1.625" OD x 0.438" W bearings)
  • Aluminum construction
  • Sealed cartridge bearings - sealed and self-lubricating
  • Two bearings per bottom bracket
  • Uses the same size bearings as regular Profile American/Mid bottom brackets
  • Colors: silver, red (added later)
  • MSRP: $99.95 USD (approx.)
  • Made in the U.S.A.
  • Nomenclature: ID = inside diameter, OD = outside diameter, W = wide

I just bought one of these Profile Evolution bottom brackets (chrome, with red wrenches) for $100.00 cash (5/5/2015).  They never really caught on in the mid-2000's, but they're kind of unique.

Price: N/A
Color: Polished

Profile went to the drawing board wand came up with a revolutionary idea for the bottom bracket. If you've tired of using a hammer and a block of wood to set your B.B. cups into your frame, you may want to check this out. All you do is slide it in and screw the two pieces together. Piece of cake. Retail price is to be determined soon.
