Hope R22 e-Bike Chainring - Black, 34T
Precision-made MTB chainring designed for reliable power transfer, broad drivetrain compatibility,...Precision-made MTB chainring designed for reliable power transfer, broad drivetrain compatibility, and long service life on modern Bosch Gen 4 e-bikes. Its asymmetric tooth profile and wide direct mount design ensure stable chain control, consistent performance in poor conditions, and dependable operation across current 1x systems.Key Features and Benefits:Bosch Gen 4 wide direct mount interface (55 mm chainline): The ring mounts directly to the motor without a spider, creating a stiff and accurate interface that keeps chain alignment correct under high e-bike torque, resulting in smoother power delivery and reduced drivetrain stress.Asymmetric tooth profile engineered for cross-compatibility: The tooth shape is tuned to work with different chain designs, allowing the chain to seat correctly across brands and speeds, which leads to quieter running and reliable shifting across mixed drivetrain setups.Compatibility with 9, 10, 11, and 12-speed drivetrains including SRAM T-Type and Shimano HG+: Broad drivetrain support removes the need for system-specific rings, giving fitment flexibility and ensuring correct engagement even on the latest transmission standards.Improved chain retention design: The updated tooth profile holds the chain securely during rough riding and high torque loads, reducing the risk of chain drop and maintaining consistent drive on technical terrain.Enhanced mud shedding capability: Shaping around the teeth and base clears debris more easily, preventing mud build-up that can cause noise, wear, or loss of engagement in wet conditions.Optimised performance at extreme chain angles: The profile supports modern wide-range cassettes and 1x setups, keeping smooth engagement when the chain is crossed, which improves efficiency on steep climbs and low gears.Extended functional wear window: The tooth design allows greater wear before engagement is compromised, maintaining drive quality for longer and extending service intervals.Spiderless construction with updated leg design: Removing the spider reduces weight while the revised leg structure increases stiffness, ensuring the ring stays stable under sustained e-bike loads.Machined from 7075-T6 aluminium: High-strength alloy resists deformation and wear, providing a strong yet lightweight chainring suited to high-torque e-bike use.Available in 34T and 36T options: Choice of sizes allows gearing to be tuned for terrain and riding style, balancing cadence, climbing control, and top-end speed.Consistent chain control and durability are central to this chainring s design. The combination of a wide Bosch Gen 4 chainline, asymmetric tooth profile, and stiff spiderless construction keeps power transfer stable under load while reducing wear across the drivetrain. This results in predictable engagement, lower maintenance demands, and dependable performance across varied terrain and drivetrain standards.Choose this chainring to ensure your Bosch Gen 4 e-bike runs smoothly, stays quiet in poor conditions, and maintains reliable drive over long distances. It is a straightforward upgrade for riders who value compatibility, durability, and consistent performance.Specification:Available in 34 & 36TBosch Gen 4 Direct Mount (55mm Wide chainline)A new range of MTB chainrings from Hope which offer a new tooth profile compatible with all major drivetrain types along with updated spider designs.Compatible with 9/10/11 and 12Spd drivetrains including SRAM T-Type and Shimano HG+Asymmetric tooth profile engineered for cross compatibility and functionality with different drivetrain systemsImproved mud shedding capabilityImproved chain retentionBetter performance with extreme chain angles on modern 1 x drivetrainsTooth profile allows for more chain wear before function is compromised, extending service lifeSpiderless rings have a new leg design with improved strength and stiffnessMachined from 7075-T6 aluminium
