  • Quality BB30 (BB386) Bottom Bracket Conversion Cups by Promend.  Allows use of 386EVO Cranks in English 68mm Bottom Bracket.
  • This set allows you to use many 386EVO cranks on standard BSA (ENGLISH) Frames.
  • Each cup adds roughly 10mm in width which means your crank axle must be at least 88mm long > 68mm +10mm+10mm=88mm. 
  • Some listings will suggest this will allow the use of BB30 cranks but this is impossible as BB30 crank spindles are not long enough.
  • Sealed Cartridge Bearings, Anodised Alloy Housing.
  • WARNING: There is very little room in a 68mm Bottom Bracket to squeeze in a BB30 Style Crank, the inside ID of the bearing cups is approx 30.4mm so you have 0.20 clearance. If your Bottom Bracket is not square, there is a possibility of the crank shaft rubbing. Also, as these are much larger than normal outboard bearings, a standard bottom bracket tool does not fit. You will require a tool such a BBT-29 16 Spline Park Bottom Bracket Wrench.. 
  • Weight: 98 Grams, made in China.
