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. It mounts directly to the crank's axle and does away with the need of a spider which means you save a whole heap of weight. The Retainer Ring is designed to work with 9,10 and 11 speed set-ups and it provides a quieter drivetrain with less drag. The ring is constructed of CNC machined 7075-T6 aluminium providing the perfect blend of light weight and strength whilst the hard anodised finish makes it ultra durable.Designed specifically for Hope ChainsetsCNC Machined 7075-T6 AluminiumCompatible with 9spd, 10spd and 11spd Set-UpsHard anodised finish

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.
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.
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.
