BioCentric EBB offers secure tension control and quick adjustments for Niner singlespeed riders
What Our Gearheads® Would Say:
“If your Niner frame uses the 55x68 EBB standard, this is the piece that keeps everything quiet and running efficiently. It’s more secure and easier to tune than many aftermarket options, and the fit is rotor-tight since it’s purpose-built around Niner tolerances.”
Designed specifically for Niner frames that use the 55mm x 68mm EBB shell standard, the BioCentric EBB delivers a stable platform for singlespeed riding with reliable clamping and smooth rotational adjustment. Its precision fit minimizes creaks, while the secure interface prevents slippage during hard torque efforts. Riders looking to maintain the simplicity of a singlespeed drivetrain—without sacrificing performance or ease of service—get a refined solution engineered to integrate seamlessly with Niner’s chassis designs.
