  • Quality BB30 Bottom Bracket Conversion set by Prestine of Taiwan.  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.
  • Double Sealed Cartridge Bearings, Anodised Alloy Housing, Plastic centre with O-rings, Spaces and wave washer.
  • 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: 100 Grams.
