Fyxation Six Fyx drivetrain conversion kit, in display box

While fixies are fun, simple and easy to maintain there are times when it pays to have a few gears at hand. While they’re adamant that they aren’t trying to ‘fix’ anything, Milwaukee, Wisconsin’s Fyxation has released a conversion kit that adds a six-speed drivetrain to your 120mm spaced frame.

The crew at Fyxation are clearly single-speed enthusiasts, but options are always good. The conversion kits are intended for fixed gear or track bike riders who want to give their knees a break, have hilly terrain to contend with, or for anyone who has a fixie that they like and fits well but would happily accept a bit more versatility. Bikerumor first previewed the Six Fyx conversion at Interbike in 2013, but the kits have just recently become available to consumers.

The functional bits of the conversion kit include Fyxation’s proprietary 120mm 32 hole bolt-on cassette hub, rear derailleur, a derailleur hanger that works with track ends or horizontal dropouts, bar end shifter, six speed cassette (12-26t), 46t front sprocket and a cable with housing. Also included are finishing touches like a chain guide and cable guide clamps for your down tube and chainstay.

The kit is also available with a complete rear Fyxation wheel, if you’re okay with the color black and don’t want to rebuild one of your existing hoops. In either kit, the one piece you have to supply yourself is a nine-speed chain. Also, you can substitute any 9-speed shifter if you don’t like the fit or feel of the supplied unit.

The conversion kit is designed to work with nearly any 120mm spaced track or fixed gear bike. The Hub-Only Kit sells for $250 USD and the Complete Wheel Kit for $300, and both can be purchased on Fyxation’s website.

I love that Fyxation will be the only source for replacement cassettes. I am not being sarcastic here.

Wouldn’t a “narrow-wide” chain ring with tall teeth be a nice upgrade for this kit?

Great, make it even more “difficult” for hipsters to fix flats. I’ve always been amazed at the number of people that buy these bikes for the simplicity(true, they’re simple and easy to work on), yet can’t even change a flat anyway.

I patch a flat with the wheel still bolted on….faster than geared riders who need to first remove their wheel to the either patch the flat or replace a tube.

Derailleurs and bar-ends look to be rebranded Microshift?

For the cassette, is it a standard shimano Hyperglide spline? I wonder if you could use these on some of the single speed mini free hub bodies like Chris King and DT Swiss.

Will there be fixed conversion kits for this conversion kit?

I find it funny that trends are swinging the other way again and all those people that bought into the fixie craze a few years back are now trying to find gearing again.

You also need to add brakes so why not just get a regular bike?

The price of swapping to this dive train is more expensive than most fixed gear frames….

This is something so inane that it boggles the mind…

Actually kind of neat. I travel with my track bike often if I find myself in a town with a track. That way I can ride the roads and the track. It’d be nice to be able to have a few gears with me.

I thought this was a brilliant idea….until I saw that you need their special hub, thus requiring a new wheel or a rebuild. Lost interest.

I hope that the derailleur hanger itself is available alone to allow the option of using better components.

Fyxation Session tires are the best ever!

First hipster who rigs one of these up on their 10sp conversion, which still has all the cable stops intact, wins.

Rebadged Microshift.

@wako29: Agreed. I think it’d be better if they could have created a cassette to thread onto FF/SS threads so you could just use what you already have.

Just like BB30 … “the solution to a problem that never existed”

If it remained fixed in each gear I’d be impressed.

Fixies aren’t for everyone. They are fun, to me anyway. Put on a freewhell and the fun goes away.

Can I convert this to single speed?

If it didn’t require a new hub/wheel I’d be all over this. I have a SS SE bike that is great for riding around in the current area I live (mostly flat) but I’m moving in a few weeks to an area with a lot more elevation change. It doesn’t warrant a full blown 3×10 drivetrain but slapping 6 gears on a fixie/SS bike that I already have (and really enjoy) would be nice. Unfortunately it looks like I’ll just be selling the bike and building one that accepts gears.
