A few years ago when the folks at Sturmey-Archer announced that they were developing a 3 speed fixed gear hub, I was super-excited. This was tempered, however, with the worry that it would never see production due to it being something of a niche product.
Then, back in March of this year, suddenly they were actually available for purchase. Naturally, I wanted one. Bad. But, given that it’s a >$200 piece of kit, I wanted to get some first-hand opinions of it before I took the plunge and had a wheel built around one. I turned to the internet (specifically to the rec.bicycles.tech newsgroup) for info. Right away I got some feedback which further convinced me that I really “need” one. The only real issue anyone seemed to have with it was the amount of lash (15° at the hub seems like a lot, but when you factor in gearing, it’s not that bad at the pedals).
Then, just a few days ago, I got an email from “Rogerzilla” which was a far more detailed and technical review than I would have ever hoped to elicit. With his permission, I’m reprinting it below.
