Heat treated 4130 chromo.... nice welds and weighs about as much as a big gulp 33oz. Double butted legs and CNC machined steer tube with integrated race.... nice attention to detail.
Made in China.... No chrome option. Redline is no longer run by and for BMXers.... owned by a huge corporation that bought Diamond Back as well.
These are as close to perfect as I could ever wish for. I've had mine for years and they have held up to tons of backflips and a few not so soft landings.
