Hope R22 e-Bike Brose/Specialized Direct Mount Chainring

The Hope R22 e-Bike Brose/Specialized Direct Mount Chainring is a precision-engineered MTB chainring designed to deliver reliable chain control, long service life, and broad drivetrain compatibility on modern e-bikes. Built around Hope’s new asymmetric tooth profile and a stiff spiderless design, it supports high torque loads while maintaining smooth, consistent performance across a wide range of drivetrain systems.

Key Features and Benefits:

• Asymmetric tooth profile engineered for cross-compatibility: The alternating tooth shapes are designed to mesh correctly with different chain standards, allowing smooth engagement across multiple drivetrain types. This results in stable power transfer and dependable shifting without the need for drivetrain-specific chainrings.
• Compatibility with 9, 10, 11, and 12-speed drivetrains: Support for Shimano HG+, SRAM T-Type, and other major systems reduces setup constraints. This ensures the chainring integrates cleanly with both current and future drivetrain upgrades.
• Optimised tooth geometry for improved chain retention: The refined tooth shape holds the chain securely under load, even on rough terrain. This reduces the risk of chain drop and maintains consistent drive when climbing or accelerating.
• Enhanced performance at extreme chain angles: The tooth profile is tuned for modern 1x drivetrains where chainlines vary more across the cassette. This maintains smooth engagement and reduces drivetrain noise when riding in harder gears.
• Improved mud shedding capability: Strategic spacing and shaping between teeth help clear mud and debris quickly. This preserves drivetrain efficiency and reduces wear in wet and gritty conditions.
• Extended wear tolerance in the tooth profile: The profile is designed to remain functional even as wear increases over time. This extends service life and delays the point at which replacement is required.
• Spiderless direct mount construction: Removing the spider reduces unnecessary interfaces and improves load transfer. This creates a more direct and efficient connection between crank and chainring.
• New leg design with increased strength and stiffness: The updated structure resists flex under high e-bike torque. This supports consistent chain engagement and stable power delivery during hard efforts.
• Machined from 7075-T6 aluminium: This high-grade alloy offers an excellent strength-to-weight ratio. The result is a durable chainring that resists deformation and wear over extended use.
• Brose/Specialized direct mount with 52mm chainline in 34T and 36T options: Correct chainline alignment supports efficient drivetrain operation. This improves shifting accuracy and reduces premature wear on the chain and cassette.

Consistent chain engagement and long-term durability are central to this chainring’s design. The combination of a cross-compatible tooth profile, high stiffness construction, and wear-tolerant geometry ensures dependable performance under the sustained loads typical of e-bike riding. This creates a drivetrain component that supports efficiency and reliability without adding complexity to the setup.
