European Bottom Brackets

If you’ve ever seen Crupi’s displays at the races, then you know first hand why our bottom brackets are unmatched by any other.  The greatest advantage to our bottom bracket is in how well it spins.  Other advantages include the simple lock rings which secure it once in place and the lateral  adjustment it has.  Multiple spindle lengths make for a perfect chain alignment every time. 

  • Spindles are available in Titanium only

  • 6061 T-6 CNC Machined aluminum cups

  • Heavy duty sealed cartridge bearings

  • Spindle lengths available are 110, 115, 120 and 128mm

  • 115 & 120 lengths are the most common

  • 110mm spindles designed to work with Dotek cranks only and will not work with Crupi or Answer cranks.
