Here at The Hub we love commuting and since commuting and internal gears go hand in hand, why not talk about FSA’s new 2-speed internal crankset the Patterson Transmission? FSA is a relative newcomer to the world of internally geared cranksets, with both the Schlumpf drive and the Hammerschmidt having been on the market for some time. The difference, for myself anyway, lies in accessibility.

I haven’t been able to justify spending the money for internal cranksets in the past as both the Schlumpf and Hammerschmidt retail in the $700 range, so i was pretty excited when the patterson transmission came on the scene at far more reasonable $300. I bought it, set it up and have been happily riding ever since.

First off, i guess it makes sense to talk about what type of bike this belongs on. the important physical restrictions are simple, the bike must have a 68mm bottom shell and fixed chain stays. you need to have down tube cable routing, but if you don’t you could always add a clamp on cable stop, so no need to worry about that. This crankset was designed by Sam Patterson (one of the founding members of Sram) for commuting, but could easily find a home on a touring bike, mountain bike, weekender recreation bike or cargo bike. ….Read More Link (will open a new window)
