which is better material? cro-moly or steel?

like which is the lightest and which could take up the most beatings?

Chromoly is a form of steel, these are the elements used to harden.

Chromoly is stronger. Anything claiming 'High tensile steel' is garbage. There are good alloys not chromo- but it is the industry norm for strong steel frames\ headsets.
>Reynolds 4130 Chromoly< the stuff BIKES are made of.

Lightness takes you to Titanium alloy. No difference prob' between regular steel and chromo- but bmx riding is a strength rather than weight consideration.

>jef.

chromoly is lighter than steel in that it takes less of it to make a strong frame than the typical 'hi ten' steel.....

so that being said, I leave you with a line from FuManchu "Out ridin... backin’ day
4130.. only way!" off the song Anodizer

Why are these bike built w\ tensile steel rear tri>angles? (seat stay\ chainstay). T-tube Chromo...


The dk featured (older model) complete front tri>angle chromo- other 2, the seat tube is 'tensile steel.'

MIGHT...mean a better build?


I think....the rear is made to fail. The soft\ hard of chromo front, tensile rear feels good to begin, after jumping the bike goes way soft rear.

chromoly of course man

the theory behind the hi ten rear end is that it is cheaper to make....so it reduces the cost of the bike......nothing more....like bikes that have a chromoly seat tube...just so they can put a 4130 sticker on the bike and not be false advertising....

Ya, that sounds right.

yeah...you're definately right about the tensile steel weakening over time though, I remember I had a huffy MJ12 that I rode for a while and after about a year or two it began to noticably bend on hard landings
