Description
The MCS 110/130 BCD Power Disc is an old-school style drivetrain adapter for riders who want to run a five-bolt chainring on a compatible BMX crank setup.
Machined from aluminium and made in the USA, it gives you the classic full-disc look while supporting both common five-bolt chainring patterns. It is especially useful on retro builds where you want period-correct style without giving up modern replacement parts.
Looks old-school because it is supposed to. Check your crank and chainring fit before ordering.
