Isnt 4130 just the industry standard code for chromo in the states?I can tell the difference instantly between an old 531 mtb and 4130 gaspipe it is far more forgiving quicker on rough stuff and far less knackering to ride it is far more than just a sticker
No my Overburys Fellrider is a much nicer more forgiving ride than a Gaspipe Diamondback I have
