Hope R22 e-Bike Shimano Direct Mount Chainring

The Hope R22 e-Bike Shimano Direct Mount Chainring is a precision-machined MTB chainring designed to deliver reliable chain control, broad drivetrain compatibility, and long service life on modern e-bike setups. Built for Shimano EP8 and E8000 motors with a 52 mm chainline, it combines a new asymmetric tooth profile with a stiff, spiderless design to maintain consistent performance across demanding terrain and drivetrain systems.

Key Features and Benefits:

• Asymmetric tooth profile engineered for cross-compatibility: The tooth shape is carefully varied across the ring to work with different chain designs, allowing smooth engagement with Shimano HG+, SRAM T-Type, and other major systems, which ensures stable drive under load and consistent power transfer.
• Wide drivetrain compatibility from 9 to 12 speed: The profile supports older and current drivetrains in one ring, reducing fitment issues and making it easier to maintain or upgrade without replacing core components.
• Direct mount interface for Shimano EP8 and E8000 motors: The direct mount design removes the need for a separate spider, improving alignment and reducing flex so torque from the motor is transferred efficiently to the drivetrain.
• Optimised for extreme chain angles on 1x systems: Tooth shaping and spacing are tuned to handle the sharper chain lines of modern frames, helping the chain run smoothly across the cassette even in the largest cogs.
• Improved chain retention under load: The alternating tooth profile holds the chain securely during high-torque e-bike use, reducing the risk of drops on rough or technical trails.
• Enhanced mud shedding capability: Open tooth geometry allows mud and debris to clear quickly, keeping engagement consistent in wet or mixed conditions and reducing drivetrain drag.
• Extended wear tolerance before performance drops: The tooth profile maintains effective chain control even as wear increases, extending usable service life and lowering replacement frequency.
• Spiderless ring with updated leg design: The new leg structure increases strength and stiffness without added bulk, maintaining precise chain engagement during hard acceleration.
• CNC machined from 7075-T6 aluminium: High-grade aluminium provides an excellent balance of strength and low weight, ensuring durability under sustained e-bike torque.
• Available in 34T and 36T options: Multiple sizes allow riders to tune gearing for terrain and riding style, supporting efficient cadence and controlled power delivery.

Consistent chain engagement and durability are central to what this chainring delivers. The combination of a stiff direct mount interface, a refined asymmetric tooth profile, and wear-tolerant design helps maintain smooth power transfer over time, even with high torque and varied drivetrain setups. This reduces unwanted noise, limits chain drops, and keeps drivetrain performance predictable across long service intervals.
