I am looking to upgrade the wheelset on my Specialized Tarmac from Ksyrium Equipe alloys that weigh in at 1690 grams. My budget will likely allow me to go for increased aerodynamics or decreased weight, but likely not both (like the Mavic Carbone Ultimate). Which would you choose?
Background: Typical week is a quick 10-15 mile ride followed by a longer ride of 30-36 miles. The longer ride clocks in at between 18 and 19 MPH average over reasonably flat, North Texas terrain (a few minor hills). I am 42, 6 foot, 160 pounds.
My goal? Do the above faster, hanging with the front group on the way back, pulling a bit more while maintaining good speed. Not looking to race: I'll never do a crit and my non-existent swimming skills make me a poor candidate for a tri. But I would like to get back into longer rallies of closer to 60 miles at some point.
I am considering a set of Williams alloy clinchers at 1350 grams versus something more aero but closer to my current wheel weight of 1690.
Thoughts?
