Niner CYA Insert

Bottom bracket standards have gotten a bit out of hand in the last few years, requiring frame designers to use one system over another. Instead of succumbing to one brand’s standard, Niner saw this as an opportunity and developed the CYA Insert. Now you can press fit an adapter for BB30, BB92, PF30, or standard English threaded bottom brackets into your CYA equipped frame. Say adios, sayonara, or Audi 5000 to conformity, and hello to options.

Use these for Shimano Cranks

  • Familiarity: I've put it through the wringer

I use these in my CYA Niner frame. Lets me use a standard threaded bottom bracket instead of a press-fit with adapter. This is my preferred setup for running Shimano with my Niner.
