ATS - Speed drive is a gearing system that makes the chainring spinning at a higher rate. For instance, 38 tooth chainring with speed-drive engaged, will work like a 1.65 times larger one (63 tooth chainring). ATS Speed drive is manufactured in Taiwan and assembled in Taiwan.


(Chain driven version / Model SD165)

- Cone ring configuration, incl. gears, crankarms kickplates chainring and chain guard - BCD110 spec.

- With two gears: direct drive 1:1, overdrive 1:1.65 /165% (We have also Model SD250 overdrive to 250%)

- Axle length : 170mm, for bottom bracket width 100 - 105mm.
