Wolf-tooth Wolf Tooth 130 BCD Flat Top Chainring

The Wolf Tooth 130 BCD Chainring is not only beautifully machined and lightweight but utilises a patented wide-narrow design that is perfectly suited to 1x setups – dropped chains are a thing of the past. Unlock your dream drivetrain configuration and satisfy your inner tweaker.

Bred from ice-cold Minneapolis winters and designed to work your road or cyclocross bike, the Wolf Tooth 130 BCD Chainring means more time riding and less time fumbling with dropped chains.

In line with Wolf Tooth’s guiding ethos of providing unrivalled design innovation, reliability and durability, this chainring employs a patented Drop-Stop® wide-narrow tooth profile which not only keeps the chain securely in place on single chainring setups but dislodges mud, dirt and excess precipitation more efficiently. For additional security in extreme conditions, this chainring is best used with a clutch-type rear derailleur.

Synonymous with ultra-high-end custom builds and stalwart steeds alike, Wolf Tooth chainrings are machined entirely in-house at Wolf Tooth’s HQ in Minnesota, USA. The anodised finish and machined lettering that adorn every chainring bear the hallmark of master craftsmanship.

If you’re a discerning cyclist looking to invest in a premium-grade chainring that’ll outlast its competitors and function perfectly on a 1x set up, this is the only way to go.

Key Features:

• Patented Drop-Stop® wide-narrow tooth profile for minimised dropped chains
• Perfect for 1x setups
• Machined in-house at Wolf Tooth’s HQ in Minnesota, USA
• Beautiful anodised finish

Compatibility:

• These rings are for use with 130 BCD 5 arm cranksets. 
• Does not fit on the cranksets for Shimano DA 9000 / Ultegra 6800
• Not compatible with Campagnolo CX10/11.

Chain Compatibility:

• 9, 10, 11, & 12spd Eagle – These chainrings are designed to work with all 9-speed, 10-speed, and 11-speed chains. They also work with 12 speed Eagle and 12-speed KMC chain. They do not work with Shimano 12 speed Hyperglide+ chain or SRAM 12-speed Flattop chain.
• If using a 9-speed drivetrain use a 10-speed chain as it fits tighter for better chain retention.
• Sram Exogram cranksets with inset nut must use stock fifth bolt + spacer(s). The Force CX1 bolt features fifth bolt with a 1x specific shoulder. This kit can be found online. 
• Can be mounted in either the big or small ring position of a double crankset given chainstay clearance in the small ring position.

38T important note: The chain may contact the spider arm slightly when using the 38T chainring

We recommend filing a small chamfer on the spider arm but you can also just install it and let the chain do the work. This is only an issue with the 38T as the 130 BCD was designed for a 39T smallest ring.

Occasionally, without notice, manufacturers change product design and/or specifications.
