I look for a stem for my fixed gear bike. I want a really stiff one but it would be nice if it a lightweight as well. Of course this is a contradictory but try to find a good compromise. Does anyone has any experiences with the Extralite RoadStem OC? It's pretty light but is it also pretty stiff? Or would suggest something more like the new 3T ARX LTD or do you have any other ideas? I weigh about 172 lb (78kg) and I like to accelerate my bike ;-)

Cheers
