Hope E-Bike Chainring - Bosch Direct Mount - Spiderless - 34T/36T

Description

Hope E-Bike Chainring – Direct Mount for Bosch Motor Systems

Upgrade your Bosch-powered e-MTB with the Hope E-Bike Chainring, specifically engineered to withstand the extreme torque and demands of electric motor assistance. CNC-machined from a single piece of 7075-T6 aluminium billet in Hope’s Barnoldswick facility, this spiderless direct mount chainring delivers unmatched durability and performance.

Engineered for E-Bike Torque

E-bike motors generate significantly more power than human legs alone, placing enormous stress on drivetrain components. Standard chainrings simply aren’t built to handle these forces. Hope’s E-Bike Chainring features a reinforced leg design with improved strength and stiffness, ensuring it can handle the constant high-torque output of modern Bosch motors without flexing, wearing prematurely, or failing.

The hard anodised finish provides an ultra-durable surface that resists wear and extends the chainring’s service life, even under the punishing demands of assisted climbs and aggressive riding.

Direct Mount Spiderless Design

The spiderless design mounts directly to your Bosch motor, replacing the full spider assembly for a lighter, cleaner, and more elegant setup. This direct interface eliminates unnecessary components whilst maintaining the strength needed for e-bike applications. The result is a streamlined drivetrain with fewer parts to maintain and a more refined aesthetic.

Advanced Tooth Profile Technology

The asymmetric tooth profile represents years of development and testing. Engineered for cross-compatibility with different drivetrain systems, this profile delivers:

Superior chain retention without requiring a chain guide
Improved mud shedding to maintain performance in wet conditions
Better performance with extreme chain angles on modern 1x drivetrains
Extended service life as the tooth profile allows for more chain wear before function is compromised
Quieter operation with smooth, positive chain engagement
The narrow/wide tooth pattern keeps your chain securely in place, even on rough terrain or during aggressive riding, eliminating dropped chains and the need for additional chain retention devices.

Universal Drivetrain Compatibility

The Hope E-Bike Chainring works seamlessly with 9, 10, 11, and 12-speed drivetrain systems, including the latest SRAM T-Type and Shimano HG+ technologies. This broad compatibility means you can upgrade your chainring without worrying about drivetrain limitations or future-proofing your setup.

Precision CNC Manufacturing

Each chainring is CNC-machined from a single piece of 7075-T6 aluminium billet – the same aerospace-grade material used in aircraft structural components. This manufacturing process ensures perfect tooth profiles, precise tolerances, and consistent quality across every chainring. No stamping, no shortcuts – just precision engineering.

The single-piece construction eliminates weak points and ensures the chainring maintains its shape and performance under the extreme lateral and torsional forces generated during e-bike riding.

What Experts Say

Blister Review tested the Hope E-Bike Chainring and found: “The chains all mesh nicely and run quietly, chain retention is good, and I’ve promptly forgotten about the ring as soon as I started riding, which is really the most I can ask from a chainring.”

That’s the ultimate compliment for a chainring – it works so well you forget it’s there.

Why Choose Hope E-Bike Chainrings?

Whilst many riders stick with OEM chainrings, Hope’s e-bike specific design offers tangible benefits. The reinforced structure handles motor torque better than standard rings, the advanced tooth profile extends service life and improves chain retention, and the direct mount design reduces weight whilst maintaining strength.

Combined with Hope’s legendary build quality, precision manufacturing, and the ability to customise your bike’s appearance with colour-matched components, the Hope E-Bike Chainring is both a functional upgrade and an aesthetic enhancement.
