KMC Narrow/Wide 104PCD 4 Bolt MTB Chainrings - Aurora PVD

Season:2026

Brand:Kmc

Code:18396Aurora

The KMC 32 tooth chainring with Aurora PVD coating combines reliable chain retention with a standout finish for riders who want their drivetrain to perform as well as it looks.

Machined from CNC-milled AL7075 T6 aluminium and built for 104 BCD 4-arm spider setups, it features the same narrow-wide tooth profile found across KMC's chainring range, with alternating tooth widths that interact precisely with the chain to significantly reduce the risk of dropping on rough or technical terrain.

What sets this version apart is the iridescent Aurora PVD surface treatment, which goes beyond aesthetics to deliver genuine performance benefits, reducing friction, improving scratch resistance and corrosion protection, and extending the overall service life of the ring. Optimised to work seamlessly with KMC chains, it supports 9 to 12-speed drivetrains and any chain measuring 1.27cm (1/2") x 0.22cm (11/128"), with the sole exception of SRAM T-Type. A chainring that pairs eye-catching looks with genuine durability gains.

Features:

  • For cranksets with spider 104 BCD
  • 9 - to 12-speed
  • Optimal chain retention and mud clearance
  • Perfectly matched to KMC chains
  • Aurora PVD - reduces friction, extends product life, improved corrosion protection, and scratch resistance
  • Narrow-wide tooth profile for precise interaction between chain and chainring
  • CNC-milled Aluminium AL 7075 T6
  • Compatible with all chains size 1.27cm (1/2") x 0.22cm (11/128"), except SRAM T-TYPE
