FX Tracklocross Frameset

  • Sale
  • Regular price $ 199.99

The FX is the product of wanting to shred around on dirt with our brakeless fixed-gear frames. We tweaked specific areas of the bike to try to improve common issues that you encounter riding fixed and especially, riding fixed on dirt.

The Poseidon FX has a raised bottom bracket that prevents pedal striking even on the steepest of drops. The head tube angle is slacked so your toe doesn't hit the front tire when turning. This also offers a slightly softer ride on rougher terrain. On the small frame in particular you will see that the head tube angle is slacked the most as toe overlap is a common problem for smaller frames. You can pedal freely even through the tightest of turns on that size.

The FX frame can easily fit a set of 700x40 cross or gravel tires. 

Frameset includes Frame, Seatpost Collar, and Fork only.

These frames have been stress tested and are backed by a lifetime warranty for the frame and fork.

Still putting it together

So far so good, everything from my old bike seems to swap right over to this one, probably need to hurry up and get some frame protectors seeing how every time I put parts on a bike I meant to put little nicks and scratches on it but it's all good I'm happy with my purchase

Not compatible with 144 bcd spiders

I have SRAM Omniums that I cannot use because the spider arms hit the frame… I had planned to use this with 1/8 chain set up but I can’t now. This frame is ok for the money but limited to 130bcd rings which makes it useless for me.

Hey so sorry you had trouble with your omniums. This is precisely why we recommend a square taper bottom bracket for the build and we made sure that it was clearly listed in the product specs so folks know what it is compatible with before purchasing.

Bad Ass

I have only done a test ride around the block after getting the frame built up but it looks really good! I was amazed at the quality for the price! It’s also super light! Cannot wait to get it out on the trails!
