Mavic Wheel Upgrade? Cosmos to Cosmic or Ksyrium Elite?(4 posts)

Mavic Wheel Upgrade? Cosmos to Cosmic or Ksyrium Elite?Ray G
Jul 14, 2003 8:45 AM
My current ride is a Litespeed Capella that came with Mavic Cosmos wheels. I like the wheels, but would like to bump up to an aero wheel. I don't have a ton of money and will sell my Cosmos. My question - is it worth the money to jump to the Ksyrium Elites, or should I pocket the money and upgrade to the Cosmic Elites? I'm not racing, so weight is not a huge factor.

Why am I jumping up? I am sure part of it is now psychological, but my rides are all averaging >19.6 MPH and from what I understand, I can benefit from an aero wheel.

Thanks

I bought my new ride with the Mavic Cosmic Elites after advice from my LBS. The guy there who is a very good rider rides them as his training wheels and says they are great and would be all I would need for quite awhile. The only thing that I have found is that after a few rides some of the spokes loosened and I had them tightened up. They said this is normal for most aero wheels in that they come built and need some fine tuning after a few rides as they "break in".

Best of luck.

My KEs took a lot of truing before they became reliable. They seem to be fine now but I haven't ridden that much lately.

I've noticed that it's eaiser to maintain speed with KE but that could just be inertia as opposed to aero - the damn things are downright heavy. If I could do it all over again, I would buy Open Pros with DA hubs and put the extras toward other upgrades.
Bad news - Ks are NOT aero!Kerry Irons

Kysriums are NOT an aero wheel. Good for maybe 0.1 mph at 25 mph compared to a 32 spoke standard wheel. Over 100 miles, that means a savings of less than 2 minutes. Huge if you're doing 100 mile time trials. Meaningless otherwise. Get yourself some "conventional" wheels built on Record or DA hubs with Velocity Aerolite or MAVIC Open Pro rims. You'll get all the performance of the Ks for a lot less money in a wheel that can be maintained by any decent bike shop, or by you with a little bit of practice.
