The Hope Oval Spiderless Chainring is CNC machined from 7075-T6 aluminium and provides the perfect blend of low weight and strength. It's compatible with 1x10, 1x11 or 1x12 speed drivetrains and has a hard anodised finish, which provides lasting durability in all conditions. Specifically designed for use with Hope's own cranksets, this Hope Oval Retainer Ring opens up a wide range of tooth count options compared to the standard 4-bolt type. Its specifically tuned 12% ovality helps to smooth out your pedalling action and make those extended climbs to the top of the trails less painful. Also, when you're on the way back down again, you'll enjoy excellent chain retention thanks to its narrow/wide tooth profile. When used along with a clutch style rear mech, you don't need a chainguide, so overall weight is reduced and your drivetrain runs quieter and with less drag. Standard and Boost Oval rings are available in a 28/30/32 and 34 tooth sizes. Standard Oval ring available in our 6 different colours (Boost only available in Black). Choose between Standard or Boost offset to get the best possible chainline. Technologies: - 12% Ovality and 113 deg clocking. - Oval direct mount retainer ring designed specifically for Hope cranksets. - Narrow/wide tooth profile means no need to run a chain device. - Allows the use of a wide range of tooth count options. - Saves weight without the need for a separate spider. - Ability to run a broader range of smaller chainring sizes. - Provides the perfect blend of lightweight and strength. - Offset to give the perfect chainline. - Quieter drivetrain and reduced drag. - Sold individually.
This Hope Spiderless Retainer Ring is designed to complete your Hope cranks by directly mounting to the spline. Optimising strength and reliability, it's made from a lightweight aluminium for excellent toughness without any weight penalty.
The narrow/wide chainring is designed to retain the chain without the need of a chain device. The Spiderless Retainer Ring Boost will help to save weight without need for a separate spider and enable you to run a broader range of smaller chainring sizes.
Developed over many years the Hope EVO spiderless crankset has been designed using the latest FEA (Finite Element Analysis) tools and extensive multi-discipline field testing. These cranks feature a unique expanding spline axle/arm interface (pat pending). This is a perfect choice of replacement for your old or worn-out existing model for a more lightweight and stiffer off-road performance than ever before.
Its narrow/wide tooth profile holds the chain tight and eliminates the possibility of the chain dropping when using a modern clutch rear derailleur. The oval chainring design is effective because the rider does not produce an even power output with a normal circle chainring. When using a standard circle chainring, the power consistency is only relative when the rider’s feet are pushing downwards. With an oval chainring, the power output is balanced and you will actually feel power being applied at all stages of the pedal rotation.

Hope's original crankset was a huge hit, but Hope being Hope strived to improve them. The result is the new EVO Crankset. 15% lighter, stiffer and easier to install and remove, the Hope Technology EVO Crankset sets a new benchmark for aluminium cranksets.15% lighter and stiffer than the original Hope CranksetNew self-extracting axle/arm interface for ease of fitting and removalVersatile Spline mount for chainring or spiderless chainring Spiderless cranks supplied7075 aluminium 30mm oversized axle and 7150 aluminium crank arms are incredibly stiff & strongLightweight at just 560g (170mm spiderless cranks arms inc. axle)Using their tried and tested forged and CNC machined aluminium construction method, Hope fired up the latest FEA analysis tools and got to work on improving the original Hope crankset. After rigorous lab and field testing, the resulting EVO Crankset is 15% lighter and stiffer than before and now features a self-extracting axle/arm interface. This makes the cranks incredibly easy to install and remove and doesn't require proprietary tools like the original crankset.The versatile spline mounting system remains the same, so one crankset can be used with single or double chainring spiders as well as the stylish direct mount single chainrings that look incredible. The 30mm 7075 axle provides excellent stiffness and is compatible with the same 30mm Hope bottom bracket to ensure excellent longevity. The stylish anodised aluminium arms are laser-etched and machined to ensure they look fantastic for longer; no signs of heel rub on the arms after one ride here! Lighter, stiffer and still drop-dead gorgeous, the Hope Technology EVO Crankset is the perfect finishing touch to any bike that is calling out for patriotic and stylish kit.
The Hope Spiderless Retainer Ring Boost is designed specifically for their new cranks and uses a narrow/wide design to grip onto the chain and stop it from dismounting when riding over harsh and uneven terrain, which theoretically means you can ditch your chain guide for this simple and clean looking system.
