Compact planetary transmission

Compact 7 speed planetary transmission section. Its narrow width allows us to fit the hub, including the shift actuator, within the rear triangle of the frame. Everything is well protected, inboard of the chainstays and seatstays. Compact 14 speed transmission. 7 speed main series, with a reduction gear –Wide gear range, with evenly spread ratios. –Lowest ratio of number of planetary gear series vs. the number of gears of any gear hub –Lowest ratio of weight vs. the number of gears.

Non compound planetary gears

7 speed planetary series, with non-compound planetary gears offers higher torque capacity with reduced build space.

Reduction gear

Reduction gear

Utilizing a design with a reduction gear allows us to double the number of gear ratios, with only a minimal weight/size penalty. The result is closer gear ratios and and impressive gear range of 543%. For comparison, a 10-42T cassette has a range of 420% and a 10-50T cassette has a 500% range.

The first internal gear hub that accommodates a 12mm through-bolt, yielding a total of 14 speeds out of just three simple planetary series. Also, the lightest full-range 14-speed gear hub on the market, weighting just 1400 grams. For even more practicality, we've designed the XIV with a wide gear range of 543% between the first and fourteenth speed, and 13.9% gear
