If you want an all black stem that's light and strong enough for enduro why not the Race Face Turbine? It's lighter than the apex. I have one on my Rocky Mountain Altitude and it's plenty stiff. Or is it the wrong flavor Kool aide?
I have the Altitude too... the Turbine is 6 deg stem (&55mm) , which means you kinda have to run it going down, otherwise it looks lame... would have been nice if it were 0 deg.
I have a Thomson 4x... but it's silver, so it's on the frankenbike. Looking for a new 50mm stem, been looking at the Apex, but personally I think it looks ugly unless you have it on a pimped out DH bike... in which case you'd go a strata or direct mount anyway...
I've never broken a stem before... the Easton Haven stems look sleek... reckon they'd be ok for Enduro/DH?
