Supercross BMX | SX450 - Cro-mo BMX Race Frame

Sold out! Thank you for believing in this project.

Steel is real!! Don't Believe? The SX450 proves it!

You have to know your history, and pay respect to your roots. BMX started decades ago on modified Schwinn Sting -Rays® which were hi tensile steel, brazed and mig welded. Basically death traps by today’s standards. A few BMX dads started to modify these old bikes, and a few even decided to start using Cro-mo tubing that they had been using for their race cars and dragsters. With that the first modern BMX Frame was born.

Now with Supercross, we didn’t build the first modern BMX race frame, heck I don’t think we were even in the first 50 BMX Brands to build frames, but when we did start, we built Cro-mo , which 30 years ago was the best at the time. And the new Supercross SX450 pays tribute to that.

Unlike all the other company’s that are building Modern Retro bikes, or tribute bikes, the SX450 is built to ride. And you will want to ride it alot. Hell, Bubba nicknamed his the  "fun machine" and we think you will feel the same way too.

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 Tange Prestige, 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 ENVY and ENVY BLK race frames.

The Supercross SX450 is a limited production, we are building them in small batches. So you may want to get yours today as we are sure they are going to fly off the dealers shelves as fast as they are on the track.

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