Tough call. I like both Easton and RaceFace. However, I would probably have to cast my vote for the RaceFace stem as that's what I use on my MTB (RaceFace SYStem). This isn't to say that the Easton stem isn't any good but as long as you can find the right size, I don't see the Easton stem offering any improvement over the RaceFace. BTW, are we talking about the Easton forged or welded EA70? The RaceFace Prodigy is forged and thus is probably more durable than a welded stem. Also the Prodigy has the steerer pinchbolts placed in a less damaging (to the rider) position.
