Six Fyx Conversion Kit - Hub Only

3 reviews   |  

The Six Fyx Conversion Kit is a unique solution cooked up here at Fyxation that's designed to help you add a few gears to an existing 120mm track or fixed gear frame.  The whole point of the Six Fyx isn't to "fix" anything.  Over the years fixed gear bikes have been embraced by the masses due to their simplicity, low cost and ease of maintenance.  Over time however, many people have realized that while riding fixed is fun, there are times when gears are good as well.

Rather than having to go out and buy an entirely new bike to make it up that hill on your commute or give your knees a rest from riding fixed, the Six Fyx Conversion Kit was designed to let you turn that fixed gear frame into a six speed road bike.  Based off our proprietary 120mm 6 speed hub/cassette, the Six Fyx works with any 120mm spaced track frame, even those with a horizontal dropout. Using a combination of our hub/cassette, Fyxation removable derailleur hanger and our indexed bar end shifter, the Six Fyx let's you easily convert your beloved track frame into a six speed city bike.

Hub And Parts Kit

The Six Fyx is available in two different configurations; one with the hub and parts so you can build up your existing wheel with our system and the other which ships as a complete wheel from Fyxation. The Hub and Parts Kit includes our 120mm 32 hole bolt on hub with six speed cassette, proprietary derailleur hanger for horizontal dropout, indexed bar end shifter or thumb shifter, 46t sprocket, rear derailleur, inner cable guide, steel cable clips for your down tube, cable guides for your chainstay and cable/housing.  This set up is designed to let you use your existing rear wheel laced to our hub or so you color match the rear and front wheel using your current wheels.

The Six Fyx is a great system to help add a little speed to your commute or make it easy to charge up that hill on your way to school.  Here at Fyxation we're obviously big fans of a single cog, but if you're looking to get into riding a road bike and are considering giving gears a go, the Six Fyx is a great way to help you make that transition.

Excellent kit!

In my quest for a solution to adding gears to my 15 year old SS bike, I came across your kit. Building wheels is an old hobby of mine so it wasn't a big stretch for me to swap out my old flip-flop hub with a geared hub. Worked like a charm!

6 Fyx: A customizer's dream!

I have a simple track frame who's looks I've always loved, so I turned it into a 6 speed. This kit was the key to the build. The hub is easy to build a wheel into; for mine I was able to use symmetrical spoke lengths; the wheel builder specifically remarked on the quality of the components. For the rest of the build I didn't end up using much. Initially I was going to use the kit as-is, however that changed as the project evolved. That said, what is here is quality and all you need to get shifting. I inquired about modifying the cassette and was told you cannot. This is at least partly because the cogs are pinned (you could of course press the pins out). Instead, I picked up Miche loose cogs and built a slightly wider range cassette and ******* it right on; the cassette body uses Shimano compatible cogs and spacing. A potential gripe is the fact that unless you custom fab a frame-attached derailleur hanger, a simple wheel removal can be a bit of a pain. Also considering the fact the wheel required no dishing, there is likely room for a few more gears, perhaps a Fyx8 or something. At any rate, sorry for such a long review, but I can't say enough good things about this kit, especially for the DIY'er!
