Single ring drivetrains are becoming increasingly popular, particular on mountain bikes, where wide range cassettes now make it possible for riders to have their cake and eat it; a simple, reliable drivetrain with a massive gear range. Dedicated chainrings with narrow-wide teeth are essential for smooth operation and optimal chain retention. AbsoluteBlack specialize in cutting edge chainring technology and their Oval Sram Direct Mount 6mm Offset Chainrings are some of the best around.Oval shaping improves efficiency and traction, keeping your legs fresher for longerLightweight, CNC-machined 7075 aluminium construction is incredibly durableNarrow-wide tooth profile provides excellent chain retentionCompatible with 9, 10, 11 and 12 speed drivetrains and 135/142mm axle spacingSpecifically chamferred design runs smoothly in even the muddiest conditionsAbsoluteBlack's chainrings are some of the best you can buy, with cutting edge design and incredible quality and durability. Using an oval profile, rather than a traditional round chainring, absoluteBlack's Oval Chainrings feature an ovality of that varies from 10.2 to 14.4% depending on chainring size for optimal performance. This reduces stress on your knees and helps keep your legs fresher for longer by effectively giving you a smaller chainring in the weaker part of your pedal stroke and a bigger chainring in the most powerful part. Not only is this more efficient, the improved smoothness of your power delivery means you can benefit from increased traction in slippery conditions, which can mean the difference between cresting a technical climb or not.CNC-machined from 7075 aluminium, the chainrings are extremely lightweight yet also incredibly durable, with a specifically chamferred design to help clear mud in wet conditions while still providing excellent chain retention. Chain retention is so good that absoluteBlack are confident you can run the chainring without a chain guide. Compatible with 9, 10, 11 and 12 speed drivetrains, the chainrings can also be used with single speed chains. AbsoluteBlack chainrings are beautiful to behold, with exquisite machining, quality anodised finishes and performance to match the looks.
