Shimano got it exactly right. If you race or ride very aggressively with your club you will enjoy and benefit from this design. Light but amazingly stiff, great power transfer for hammering on flats and climbing. Terrific confident descents. I run Continental GP4000sII tires with these on a Tarmac Pro. You won't be disappointed! Biketiredirect has them under $800 on sale from time to time. Great investment! Excellent Deal!
I was looking for a stiff and light wheel set to replace my Easton EA 90s that were breaking spokes. I wanted a reputable, known brand that could be serviced anywhere. I like to climb, so I wanted something light and stiff, not necessarily the fastest set. These Dura Ace wheels are fantastic! They make the bike seem to float uphill.
Bought these to replace Mavic Ksyrium Equipe. True, bad comparison. BUT, what a difference. A lot of climbing where i ride in NorCal. Wheels are light, solid and alloy braking surface. They weighed in lighter than a new set of Enve SES 3.4 DT Siwss 240s.
Very smooth and a lot more forgiving but at the same time more direct power than the Ksyrium. So much so that even i could notice it immediately. My only gripe is that for so much money, they could have had Ti skewers. Guess you need to spend thousands before you get $ Ti skewers! Would be a no brainer climbing wheel with Ti skewers. Lost a star on that. Performance 5 stars. Comes w wheel bags.
