Bobby - I don't know. I think I'd just sit on the seat and take my feet off the pedals, brake, and shift back into the harder gear in order to slow the pedals down enough to re-engage. The scenario is frailin' down a hill in top gear, then dropping (accidentally) into low gear, right? Philip

Philip: That's exactly what I'd do, too (but I'd probably throw in a woob woob woob...). Seriously, I'd expect the wheel speed wouldn't change with the shift, so the crank rotation would instantly accelerate... But if your feet are firmly strapped in and you offer some leg resistance

I heard back from Sam Patterson... One of his testers has logged 5000 miles on the Metropolis using a fixed cog... but I was surprised to discover the Patterson Transmission actually freewheels; it doesn't engage like a typical fixie. He said you CAN ride it with a freewheel or fixed gear, but

So could I use this to make my alfine hub a 16 speed setup? I am only wary of the way that the gear cable has to be routed around the plastic anti-turn unit. I think if i had this setup I would fashion a small groove in the top so the cable cout run over it rather than under. But that is just my

Nice! I got two speeds out of my SimpleOne by using a SRAM Automatix 2 speed hub with which I have been very satisfied at approximately 6000 mostly commuting miles. Your solution has one distinct advantage in that you could do a two speed fixed gear if you wished. David Charlotte, NC -- You

Awesome! If the FSA doesn't work out fixed, but you fall in love with the idea of a two-speed fixed-gear, Schlumpf's cranks were redesigned a few years ago to be fixed-gear compatible: http://www.haberstock-mobility.com/en/products/schlumpf-drive.html Overview Schlumpf-for-fixed from German

I'll chime in as a fan of the S3X hub. I wonder about the FSA crankset for everyday (i.e., high gear) use. In my experience with IGH systems, they work best when you are in direct drive (the S3X is in direct direct in the top gear; 2nd and 3rd use the internal gears). Can you feel the gears in

I don't think there's anything wrong with the S3X (unlike the Schlumpf, I've built a couple of S3X wheels, one for myself), but being able to use your existing wheelsets is an advantage, as is having different shifter options. Or just having fun by solving a problem in a different way. You could

I haven't tried the S3X yet, but it sure looks like a cool idea. I run a flip-flop hub, so with the Metropolis I can have a choice of FW or Fixed (pretty much on-demand), as long as I carry my 15mm wrench for the rear wheel nut. Eric, you can slightly feel the gears working in high gear (a

I have an S3X wheel that's about to go back into service. I like it. You can also slide two splined cogs on for a dingle setup on the 3sp fixed IGH. Conceivably you could have a low range and a high range. I had that setup, but changed out the cranks before I actually used the low gear range.

Philip: I'm curious... When you're flying along at a pretty good clip (in 3rd gear, fixie mode) and you're wheel is spinning at, say 120+ rpm, and you downshift to second gear, does your cadence abruptly accelerate to the point of wanting to toss you over the bars, or is it relatively smooth?
