E*Thirteen Helix Race 12-Speed 13-52T Cassette - FW2HRA-110 Item # 2139118
Description
E Thirteen always strives to bring something new to the table. That's why they created the Helix cassette line – to offer unparalleled cross-compatibility without sacrificing performance.
As e-bikes have become more popular, They 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 32 kmph/20 mph, 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 1 3- 52T delivers seamless compatibility with SRAM®, Shimano®, and TRP® Shifters and Derailleurs of the same gearing count and similar cage capacity.
