Introducing the Helix Race 12-speed close-ratio cassette, tailor-made for e-bikes and optimized for steep terrain:
-
Purpose-Built for E-Bikes: The Helix Race 13-52T is designed to excel in steep terrain, where climbing speeds are high and descents are gravity-powered.
-
Optimized Speed: Paired with a 32T chainring and an 85rpm cadence, it achieves speeds at or just above 32kmph/20mph, making it ideal for e-bikes with speed-limited assistance.
-
Improved Climbing: The addition of a 52T lowest gear and closer gear steps enables riders to tackle technical climbs with newfound ease.
-
Universal Benefits: While designed with e-bikes in mind, this cassette enhances the riding experience for non-e-bike riders, optimizing cadence on steep climbs and letting gravity assist on descents.
-
Compatibility: The Helix Race 13-52T is compatible with SRAM, Shimano, and TRP 12-speed drivetrains, offering precise shifting and extended wear life.
-
Durable and Lightweight: Weighing in at 467g, it's sturdy enough for high-powered e-bikes yet light enough for weight-optimized trail bikes.
Experience the advantages of a close-ratio cassette on your next ride with the Helix Race 13-52T.
Key Features:
- Close-ratio gearing for better cadence and improved shifts under load.
- Lower fatigue and extended range, with an optimal cadence for maximum efficiency.
- Cross-compatibility with Shimano, SRAM, and TRP drivetrains and chains.
- Replaceable aluminum and steel clusters to reduce service costs.
- Patented two-piece aluminum/steel construction for strength, stiffness, light weight, and durability.
- Reinforced for e*spec strength.
- Available in five bold anodized or PVD color options.
- Rigorously tested for both analog and e-bike use.
