Sturmey Archer ‘S3X’ 3-Speed Fixed Gear Hub
What started as a patent for a three-speed internal gear hub has now been refined over the past century by the Sturmey Archer brand. With the new S3X hub, fixed riders can finally get the internal gearing that made the brand famous. The threaded driver accommodates a single speed freewheel for a non-fixed three-speed conversion while the aluminium lock-ring and spacers achieve chain lines of 42-45mm. In the end, you get three rather useful ratios that you can tune with the different sprockets, all within a hub that weighs less than one kilogram. The S3X hub is available now at T R Bikes.
