This 30mm external BSA bearing is the option you need so you can use BB30 cranks in your standard threaded frame.
 
Features:

  • New advanced non contact Labyrinth seals give buttery smooth spinning with unparalled protection against dust, water and mud
  • Road version
  • Only 96g
I bought this as a replacement for the previous Rotor BSA30 I had, which lasted for around 3 years of continuous use before the ball bearings gave up. A little longer lifetime would be nice but these components are subject to wear. Supplied with tool for fitting. Quick service by Merlin as always and the cheapest price around.
