Wheels Manufacturing 46mm ID Bottom Bracket Spacer Pack
Wheels Manufacturing 46mm ID Bottom Bracket Spacer Pack Info
Getting chainline right in a press-fit bottom bracket system often comes down to fractions of a millimeter — and that's exactly what the Wheels Manufacturing 46mm ID Bottom Bracket Spacer Pack is built for. Machined from black anodized 6061 aluminum, this six-piece spacer set gives you the fine adjustment range to dial in bearing preload, correct chainline, or adapt crank compatibility across shells with a 46mm inner diameter.
The pack includes two 2.5mm spacers and four 1.0mm spacers, so you have enough combination flexibility to handle most real-world fit scenarios — whether you're running GXP cranks and need to shift chainring position, or working with a frame that requires shell width adaptation for broader crank compatibility. The anodized finish resists wear and corrosion, and the machined tolerances keep things precise where sloppy fitment would otherwise cause drivetrain noise or bearing issues.
