absoluteBLACK is dedicated to producing the world's finest oval chainrings and were the first to crack the code to discover the correct shape and 'clocking' to make an oval chainring work. They learned how to maximize the part of the stroke where power is produced and minimize resistance where it isn't which has the effect of smoothing out the delivery of power throughout the pedal stroke and improving efficiency. Many other brands have followed suit since then, but what sets absoluteBLACK apart is that they don't rely on the same formula across all sizes. The shape and timing of the oval is unique for every chainring size to ensure the pedalling solution is perfect for each one.

Every absoluteBLACK chainring is designed and manufactured in Europe with premium materials and outstanding attention to detail. Not every oval chainring out there is equal to an absoluteBLACK.

Note: As every chainring size has a unique shape and design, the chainring you receive may not be an exact match for the image displayed.

Who's this item for: These are perfect for any rider looking for a premium chainring that will improve the power delivery and efficiency of their pedal stroke. XC, Trail, and Enduro riders will love the benefits these chainrings provide.

Number of teeth: 28 - 34T depending on the model chosen.

Mounting style: These are 4-bolt chainrings but see the link below if you're after a direct mount option.

The 30T 104BCD option comes with special bolts and spacers included.

Offset options: As these are 4-bolt chainrings the offset will be dictated by the spider rather than the chainring.

Chain retention technology: These chainrings use absoluteBLACK's unique narrow-wide tooth profile for optimal chain retention.

Weight: Varies between models but could be somewhere within the realm of 44g for a 30T to around 60g for a 34T.

Compatibility:

• 9-12 Speed options are compatible with 9, 10, 11 and 12spd Eagle.
• 12 Speed Shimano options must only be used with Shimano Hyperglide+ 12 speed chains (due to different thickness of the teeth).

Pros: Premium design and manufacturing. Optimised pedal stroke to enhance your power delivery while saving your energy.

Cons: Oval chainrings aren't for everyone and they might feel a bit weird or 'lumpy' until you get used to them.
