Supercross BMX | SX450 Bubba Harris Edition Cro-Mo BMX Race Frame

The SX450, it started out as a Cromo BMX Race Frame that evolved from our UL series, and quickly became Bubba's go to bike, so why not give the 2023 Hall of Famer, 3 time ABA #1 Pro and UCI World Champ a signature bike of his own. He calls it his Fun Machine, his head to the skateparks, the trails, the track, it goes with him everywhere he goes, and after all, isn't that what your bike should do? 
 

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.
