Last night a couple 19 tooth 1/8" track cogs arrived in the mail. I went downstairs, stuck the Rudge Clubman in the stand, took off the rear wheel and mounted the cog, snugged it down, then the lockring.
I took a ~14 mile ride this evening on the Clubman as a fixed gear.
Lately I have been having these moments of joy from riding, or grabbing my Pentax MX with 50/1.4 lens, or picking up a live cicada. It was a blast to ride the Clubman as a fixed gear. This is actually the most I've ridden the bike, even more than with the 16/20 freewheel. It's like rediscovering a bit of the real fun of riding. This bike has me so connected; the gear ratio is good, the chain slack is just enough to allow smooth rotation, but also perfect for track standing. I did a good minute trackstand waiting for a traffic light to turn on my way to the Schuylkill path. It's just so much fun. My legs feel a little more like noodles than they usually do, but that's good. Knees don't hurt, everything feels good.
Here's a photo of the Rudge Clubman just before East Falls.
So, this has me wanting to ride more fixed, for more utility. I need to lose some weight and strengthen my core, so riding a single speed is one thing that will expand the workout I get when on the bike. Riding a fixed gear (with brakes) will really open up my cadence to putting power down at whatever RPM I need. As I was riding up Spruce St. through the U. Penn campus, I was thinking that 46/19 is a good ratio while I get my legs back but I may need to step it up to 46/17. For now the ratio is perfect.
Anyway, the next project is brewing in my mind. I need to find a skilled welder who can make me a set of "dingle" cogs; two fixed gear cogs, welded together which use a single lockring. The smaller, outer cog is machined with a wider opening, then welded onto a steel spacer to provide the offset from the larger inner cog. Surly used to make the original "dingle" but stopped production a while back and anything out there is NOS. If anyone can find me a genuine NOS Surly Dingle cog for a 1/8" chain, I'll give you a working camera or two.
Then I'm looking for a 57cm frame with LONG Brev. Campagnolo 1010A dropouts. Broker that deal and a few cameras, a motion picture camera, and a lot of film.
I'm looking forward to riding more.
