External T47-e30 for 30mm spindle Cranksets

This bottom bracket will fit any crankset with a 30mm diameter spindle on a T47 frame with 68mm wide bottom bracket shell. Exceptions are for short spindles in proprietary cranksets, like Cannondale SiSL2 or Specialized FACT cranksets with Quarq Power meters. Other cranksets built after 2016 should be good to go. Check in with our office via info@kogel.cc or 915.777.5666 if you are unsure. This Kogel Bearings T47 external bottom bracket can be installed with Park Tool BBT-79 or any 12-notch bottom bracket tool fittings with a nominal inner diameter of 44mm. Choose road bearings for road bikes, cross bearings for mountain bike, gravel and cyclocross or if you frequently ride your road bike on wet roads.
