Niner CYA Insert Threaded, One Size

What Our Gearhead(R) Experts Are Saying: "Being able to swap between threaded, PF, or BB30 standards on the same frame is huge. I've used these inserts on older Niner builds and they've always been solid-no creaks, easy installs, and it's awesome not being locked into one BB standard when rebuilding a bike." We love the CYA Insert for the freedom it gives our CYA-equipped Niner frames. Instead of being locked into one bottom bracket standard, this aluminum insert system lets us choose what works best for our build-whether that's a classic English threaded option or one of the many press-fit styles commonly used today. It's a simple, durable way to future-proof our frame and make drivetrain swaps easy. Press-fit or threaded, road or trail, upgrades or full-on rebuilds-this insert keeps our setup adaptable. Each option installs cleanly into the CYA shell for a stable, creak-free interface that's ready for miles of riding. For riders who like flexibility and long-term compatibility, it's one of the smartest small components to keep in the toolkit.
