A chainring from Onyx which uses a simple idea to bring you a brilliant build

Do your chainring bolts spin when you install the ring, do you jam in a large flat headed screwdriver, or maybe even have the proper Park Tools ‘Chainring Nut Wrench’. Well all that headache and scuffed knuckles can be a thing of the past with the 4 Bolt chainring from Onyx.

“The bolts are included as ‘standard’ chainring bolts will not work with the cleverly designed Onyx ring.”

The chainring is CNC-machined from the highest quality aluminium with an anodized finish and available in 42, 43 & 44 teeth options and includes 5 chainring bolts. The bolts are included as ‘standard’ chainring bolts will not work with the Onyx ring, the back of the chainring has a hexagonal recess that accepts the included bolts eliminating bolt rotation during installation. This is a simple, but very a effective idea.

Only Compatible with Onyx chainring bolts, which are included.
