104pcd 4 Arm Narrow/Wide MTB Chainrings

The KMC 32 tooth chainring is built for riders running a 104 BCD 4-arm spider setup who want reliable, secure chain retention in demanding conditions.

Machined from CNC-milled AL7075 T6 aluminium, it delivers a strong, lightweight construction that holds up well under sustained load. The narrow-wide tooth profile is the standout feature here, with alternating tooth widths designed to interact precisely with the chain and significantly reduce the risk of chain drop on rough or technical terrain, making it a particularly strong choice for off-road and gravel use where mud clearance and consistent engagement matter most.

Optimised to work seamlessly with KMC chains, the ring is compatible with 9 to 12-speed drivetrains and any chain measuring 1/2" x 11/128", with the sole exception of SRAM T-Type chains. For riders looking for a dependable, precisely engineered chainring upgrade that keeps the chain exactly where it should be, this is a straightforward and effective choice.
