STONE 130BCD 5-Bolt Aluminum Double Chainring for Shimano 11/12-Speed Road and Folding Bikes

The STONE 130BCD round double chainring is designed for 5-arm road and folding bike cranksets. CNC-machined from high-strength 7075-T651 aluminum alloy, it balances low weight, durability, and smooth front shifting.

Offered in multiple large-size combinations from 53/39T up to 58/44T, it suits riders seeking higher gearing on road bikes, folding bikes, and custom drivetrain builds.

Compatibility

Designed for 130BCD 5-bolt cranksets and compatible with:

  • Standard 5-arm cranksets
  • Many hidden fifth-arm cranksets
  • Shimano 11-speed and 12-speed road drivetrains
  • SRAM 11-speed drivetrains
  • KMC, YBN, SUMC, and other compatible 12-speed chains

Important: This chainring is not compatible with SRAM AXS Flattop 12-speed chains.

On hidden fifth-arm cranksets, the anti-chain-drop pin and black pin can be repositioned with a hex wrench before installation.

Some hidden-arm crank designs may not fit. Please check your crank structure before ordering.

Chain Compatibility

Recommended chains:

  • Shimano 11 / 12-speed
  • SRAM 11-speed
  • KMC / YBN / SUMC 12-speed

Not recommended for 10-speed drivetrains, as the chain may rub against the outer chainring in certain gear combinations.

Not compatible with SRAM AXS Flattop 12-speed chains.

Smooth Front Shifting

The tooth profile, shift ramps, and pins are engineered for fast, smooth front shifting between the inner and outer chainrings.

Correct front derailleur height and alignment matter, especially with larger-than-standard chainrings.

Front Derailleur Extender Recommendation

With unusually small or large chainrings, the stock front derailleur mounting position may not offer enough adjustment range. The optional STONE Front Derailleur Extender helps reposition the derailleur.

Recommended when using:

  • 46T / 48T small outer chainrings
  • 54T / 55T / 56T / 58T large outer chainrings

For 58/44T, we strongly recommend a derailleur extender for easier adjustment and better shifting performance.

Extender specifications:

  • Compatible with 10 / 11 / 12-speed front derailleur setups
  • Material: 304 stainless steel
  • Weight: approx. 9g

The front derailleur extender is sold separately and is not included.

Package Includes

  • 2 × STONE chainrings
  • 5 × aluminum chainring bolts

Please Check Before Ordering

Before purchase, please confirm:

  • 130BCD crankset
  • 5-bolt mounting structure
  • Chain type and speed
  • Front derailleur adjustment range

For 58/44T and other oversized chainrings, make sure your bicycle frame and front derailleur provide sufficient clearance.
