  • Geometry

The OS20 SX450 features:

- Campy Integrated Headtube

- Side Mount Disk Brake Mount

- Threaded BB

- 3/8" Dropouts

- External Brake Routing

 

Available in 3 different sizes to fit all riders and 3 stock colors (Jet Black, Show Chrome and RAW ) and more to come.

 

If one of the stock colors isn't what you want, we still do custom Powdercoat and Ceracoat to make the SX450 truly yours! Give us a call, and we will get you hooked up. 

When we designed the geometry of the OS20 SX450 we based it on the regular 20" Supercross BMX Fork. Our 20" Carbon Race forks will work with the OS20 wheel, so no need to buy a OS20-specific fork. If you already have a 20" Supercross and want to go to OS20 all you need to do is swap the frame and wheels, and you are set to go! 

When we build Randy Roberts his Bulldozer OS20 RS7, one of the first calls we got was from Turnell Henry, he wanted one, but he wanted it in Cro-mo like his SX450 he has been racing. You know his Fun Machine... so the Bulldozer Fun on top of the Bubba Fun... well this is going to be the new SX450 FAS/FAS ( Fun as ... Fun as... ) so fun you have to say it twice.
 

Unlike all the other company’s that are building Modern Retro bikes, or tribute bikes, the SX450 Fas/Fas is built to ride. And you will want to ride it, alot.
 

It is classic in the form that it built from Steel ( Air Hardened Triple Butted Cro-mo to be exact ), and it is Triple Show Chrome Plated, ( got to love Chrome right? ) and it has a Retro style inspired graphic. But that is where the Retro, or Tribute style ends. After that it is all modern, and probably, if not definitely the most advanced Cro-mo race frame available.

It starts out with a full CNC machined Campy integrated head tube, a Reynolds, double / triple butted air hardened Cro-mo tube set, a Butted and tapered seatmast , a CNC’d Euro BB shell, tapered and butted seat stays and chain stays, and back side CNC’d laser cut dropouts w/ 10mm slots welded on to the cut and capped stay ends.

And of course what would all of this Cro-mo goodness be with out a full race pedigree so we build it up in our world famous and World Championship winning, Supercross geometry of the all our Supercross BMX race frames.

This run of the OS20 Fas/Fas is limited to 50 pcs. So they will sell out fast.
 

Please note this is sold as frame only. The Matching Supercross SLT forks are available by clicking here.

 

Please join the Supercross BMX Riders Group on Facebook and show off your new SX450 - Post up pics of your build and share your serial # - we would love to create a registry for everyone to keep track of these limited edition builds.

NOTHING RETRO ABOUT THIS FRAME!!!

Finish and details on this frame are above the last 10 frames and brand I have purchased the over past two years. I have 2000.00 frames that lack in finish and machine work when compared to this frame. Being a larger rider at 6 foot 3 with a 34-inch inseam I feel this frame was made for me!!! Thank you, Bill, for all the updates along the way. Best customer service!!!! Thank You!!
