How should the decal with the info on frame material be read? Here's a photo from an ad for a Mongoose Maneuver:



I thought the whole frame (with the possible exception of the fork) was 4130 CrMo. However, when I went to bikepedia and looked up this particular model of Mongoose I saw:
Frame & Fork

Frame ConstructionTIG-welded steel
Frame MaterialChromoly seat tube/hi-tensile steel
ForkMongooseFork MateralHi-tensile steel, unicrown crown
Rear ShockNot applicable

I'd rather not buy a bike with a hi-tensile frame. So which description is correct? Or maybe I'm not aware of something included in either piece of information, in which case I'd appreciate any additional tips.
