At e*thirteen, we're always striving to bring something new to the table. That's why we created the Helix cassette line – to offer unparalleled cross-compatibility without sacrificing performance.
As e-bikes have become more popular, we set out to engineer a close-ratio cassette specifically for them. Enter the Helix Race 13-52T - a new 12-speed close-ratio cassette specifically engineered for steep terrain where climbing speeds are high and descents are gravity-powered.
The 13T, combined with a 32T chainring, at 85rpm cadence, will deliver speeds at or just above 32kmph/20mph, just beyond the speed-limited assistance of most e-bikes. The 52T lowest gear and closer steps help riders clean the most technical climbs with newfound ease.
While the Helix R 13-52T was conceived for e-bikes, it also improves the ride experience for non-e-bike riders, allowing all riders to optimize cadence on steep climbs and let gravity do the work on descents.
Like all e*thirteen Helix cassettes, the Helix Race 13-52t delivers seamless compatible with SRAM®, Shimano®, and TRP® Shifters and Derailleurs of the same gearing count and similar cage capacity
Experience the advantages of a close-ratio cassette on your next ride with the Helix Race 13-52T.
