That’s why we created the line of Helix boxes, to offer unparalleled cross -compatibility without sacrificing performance. Since the e-bikes have become more popular, we have set ourselves to design a cassette with close relationship specifically for them. Here is Helix Race 13-52T, a new 12-speed rapt-speed bond designed specifically for steep soils where climbing speeds are high and the descents are fed by gravity. The 13T, combined with a 32T crown, at a cadence of 85 RPM, will provide speed equal to or just greater than 32 km/h/20 mph, just beyond assistance at limited speed of most e-bikes. The lowest gear of 52T and the closer passages help cyclists overcome the most technical climbs with newly found ease. Although the Helix R 13-52T has been designed for e-bikes, it also improves the driving experience for non-e-bike cyclists, allowing all cyclists to optimize the cadence on steep climbs and to let the gravity do The descent work. Like all Helix and*Thirteen boxes, the Helix Race 13-52T offers cross-compatibility seamlessly with SRAM, Shimano and TRP 12S transmissions and a better precision of change and duration. Experiment with the advantages of a close relationship in your next race with the Helix Race 13-52T.
