    Mavic Ksyrium Es vs Mavic Ksyrium Equipe

    I've got a pair of Ksyrium Equipe as training wheels.

    There's a difference in weight.
    How much of an upgrade are the hub?

    How much difference would a set of Mavic Ksyrium Es be on acentury+ rides.

    Would I see that much difference if I only average about 17-18 mph now on a century and 19-20 mph on a 50 miler flat.

    How much difference could I see on a 10 mile climb?

    Any input would be appreciated.
    I ride a bianchi 1885

    Both the rim and the hub are an upgrade. I don't have details on the hub, but the rim is quiet a bit lighter and uses a better alloy. I suspect that the hub uses better bearings and better freehub design, but I don't really know.

    Very little. On flat roads at 20 mph, a 200 gm weight savings is good for 0.01 mph, or 2 seconds saved per hour. A good set of aero wheels would save you 5 minutes in 100 miles, and neither of these is aero at all.

    Same answer as for a century ride.

    You don't specify how steep the grade is or how fast you'd be going (or power output), but as an example, saving 200 gm on a 6% grade with 200 watts of power output (about 8.7 mph/14 km/hr) would give you 0.04 mph. That is a gain of 211 feet/64 meters an hour over someone with the same power output and 200 gm heavier wheels. Thought of another way, it's a gain of 16 seconds every hour.

    Thank for the advice. I'm not sure $300 at nashbar for the Mavic Ksyrium Es Rear is worth it if I don't do any racing and only do club time trials. Thank for your advice!
    I appreciate it.
