Shortish 150mm quill, good for small bikes with not long head tubes or any bike where you don't need the bars so high.
Hot forged means these aren't as strong as the cold forged Tallux and dirtdrops, but don't think that means that these are wimpy at all.
Note also that NITTO (and therefore we) don't consider the smallux for off-road riding. It is a strong stem, but once you say, "good for off-road, too," you're opening the doors to abusive-showoff-stunt riding, and this is not for that.
For off-road riding, get a DirtDrop. Happy Trails!
