The centrepiece of SRAM's Eagle drivetrains are the 12-speed cassettes, and the PG-1230 Eagle Cassette forms the centrepiece of the NX Eagle groupset, yet is still compatible with any other SRAM Eagle drivetrain. The PG-1230 though has a few features that set it out from the rest of the pack.11-50t range provides massive gear range and fits on regular freehub bodyPowerGlide II technology provide, smooth, slick shifting in all conditionsSteel and alloy construction is highly durable and is rated for e-bike useOnly compatible with HG 9/10 Speed freehub bodies - not compatible with SRAM XD 11/12 Speed freehubsSince the introduction of SRAM's XX1 and X01 Eagle drivetrains, the world has waited with baited breath to see when the technology would trickle down to lower price points. GX Eagle led the way and now SRAM's Eagle technology is available right down to NX level. The PG-1230 forms the basis of the NX Eagle Groupset, by providing the same wall climbing 50t bottom cog as the other groupsets, while the use of an 11t top cog means the cassette fits on a regular 8/9/10 speed splined freehub, meaning lower cost and better compatibility. The cassettes uses a traditional construction method, with the biggest 4 steel cogs being pinned to a lightweight aluminium spider, and the 8 remaining cogs being pressed steel. This is cheaper to produce than the one-piece cassettes found in the other Eagle groupsets, but is also incredibly durable, with the steel construction offering incredible wear characteristics. It is also the first Eagle cassette to be fully recommended for use with e-bikes, such is its strength and durability. The SRAM PG-1230 cassette is a gateway to a massive gear range at a never before seen price point. Thanks to the PG-1230 and the other components in the NX Eagle groupset, fully featured 1x drivetrains are now available and attainable for the masses!
The SRAM PG-1130 is constructed from steel, which makes it slightly heavier but also cuts down the cost significantly. It retains the same PowerGlide tooth profile as the more expensive SRAM cassettes for fast and accurate shifting. Weight from 260g (11-26T).

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. If you need a quality chainring for your 1x drivetrain, look no further than absoluteBlack!
