Direct mount vs normal stem

Recommended Posts

I know what the difference is but what would the advantage of one over the other.

 

I had an accident incident the other day on my DH bike fitted with a standard 50mm 1 1/8" stem fitted and I think it saved bending something as when the dust had settled, I had skew bars and a bruised ego. Had that been direct mount, a credit card may have been in order...

 

Anybody have any realistic explanation apart from "because the direct mount is more expensive and bling so it has to be so..."?

I think the major claim is more stiffness, and the ability to lower the stem stack a bit more than a normal stem.

 

But how a stem mounted to the crown could be stiffer than a stem mounted to a 1 1/8" tube is beyond me.

DM: perfect alignment, zero reach stems, convenient to attach it to the top crown of a triple clamp instead of the steerer, wont twist in a bail.

Thanks guys. Still fiddling with stack height and reach so I'll stick with a std stem for now. Anybody got a 40mm Husselfelt stem lying around that they aren't using? Would be interesting to see what difference 10mm makes (and then I can transfer the 50mm to my trail bike...)
