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.
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 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.
