You may have answered my problem. EA70's - 600 - 800 miles and I have already experienced, on separate occasions, two broken spokes on drive side. I have lost confidence in wheels but Easton UK have asked me to return to them so they can examine the wheel.
And to singletrackmind: Quote "That's a build fault, not design fault. The builder simply didn't put enough tension in the wheels. Easy to fix." These are premium wheels supposedly all built to same standards by Easton - Not Joe Blogs - so presumably checked with a tension gauge.
