Fat and Fixed

After I converted the Ox from a single-speed to a 1×10 drivetrain, I immediately felt like something was missing. Perhaps being able to shift just made things too easy, too reasonable, and too efficient.

I have redressed this imbalance and restored order to the universe. I give you the Necro-Fix. Fat, fixed, and brakeless.

It’s pretty simple, really. Pedal.

Part wrangling, wheel building, and assembly by Revolution Cycles in Madison, WI.

A couple of things made getting this bike together take a little longer than anticipated:

The offset Pugsley fork is currently unavailable–in any form or color–because it’s being redesigned (so saith QBP). That meant that I could not only not order a black one to match this frame (which I wanted to do so that I could use a wheel that I already had), but that the current Pugsley frame-sets also come with a color-matched symmetrical fork (which I didn’t realize until I considered buying a whole new frame-set).

When the black offset Pugsley forks are available again in the spring, I’m going to grab one and swap it for the symmetrical Moonlander fork that I had to use to get this bike rolling before the new year. The symmetrical fork I’ll use to fat-front my Karate Monkey, or perhaps my Troll. The wheel will go with the fork.

Surly 135mm fixed disc hubs are apparently not a hot item, and so not kept in stock. QBP didn’t have one, and then did, but it turned out to be a single-speed hub. None of the other shops in town had one either. Nor did any my friends. I finally chased one down online, and it arrived on Christmas Eve. My only other options were to spend rather more money and use a Paul Disc WORD hub (or even more money on a Phil Wood hub). Thankfully, that wasn’t necessary in the end.

  1. I am waiting for someone to make a 135mm hub with 6 bolt disc mounts on BOTH sides. I use Tomi cogs on my fixed setups, and now problem solvers has them for cheap too.

  2. SW says:

    That would be rad–I’m a big fan of VeloSolo cogs.

    Of course, it would be even more of a niche-within-niche product than the fixed disc hub. So they would only make two per year.
