I've got a Easton EA50 stem on the way but don't know the height of the steerer clamp section , I've got my eye on a fork in E-Bay with an already cut steerer to go with it which will work with my existing stem - just! If the Easton stem takes up more steerer tube length I'll look for another. Easton's website was no help so hopefully someone has one of these stems & could post the measurement in mm's
