Lightning fast and feather light, with approximately 500 miles on them. Only used for racing and I'm only selling because I upgraded to carbon Zipp Tubulars with Powertap. These retail for $1,800. Selling for $1,000 OBO. Additional detail is below:
If you wanted a set of climbing wheels that felt lighter than air, but were still stiff enough to handle a sprint, you'd be hard pressed to improve on the Easton EC90 SLX Wheelset. Tipping the scales at an eyebrow-raising 1170 grams (that's barely over a pound per wheel), the shallow-dish carbon rim EC90 SLX's seem to defy Newton's laws, because even at that weight they are more than amply stiff, and as responsive in an all-out sprint as wheels twice as heavy. Now, let's be honest—if your mom ever called you “husky” as a child, or you resemble someone in a Hungry Man commercial, you will probably crush these carbon babies like a Pringle in a steam press. But if you're a smaller-to-average guy, with deep pockets and thighs as big around as your waist, you'll smoke tough climbs and sprints on these Easton wheels like Tommy Chong in Amsterdam.
