Flex in Ksyrium? Or Nucleon?(4 posts)

Flex in Ksyrium? Or Nucleon?needs new wheels
Apr 22, 2001 3:20 AM
I'm in desire of new wheels. I like the idea of the Ksyriums but according to this : the rear is flexy, or at least more so than the other wheel I'm looking at, the Nucleon.

Any users of either care to comment, or anyone else with information on the wheels!
ksyriums are plenty stout...dave

Placing wheels in a testing device to measure lateral flex provides some measure of comparison, but in reality there isn't a wheel made that can't be flexed significantly with very light pressure. See if you can't easily push your current wheel into the brake pad with a light push. Testing only one wheel of a particular brand is also not very scientific. Significant variations can probably be found between several wheels of the exact same build.

I switched from Shamals to Ksyriums and never noticed the Ksyriums being more flexy (which they supposedly are). I've found that they feel pretty darn stiff.

I find the braking surface on the Mavic rims to be superior. They are not only machined, but also welded at the seam. Campy rims often have mismatch at the seam, even after machining.

I bought the Nukes because they're lighter. For me, if the Nukes are lighter and flex less than the other brand then I'd go with the Nukes.

Flex is not something you need to worry about. The Ksyriums are pretty stiff with nice tight response. I did manage to take my rear out of true, but it was the result of a hard crash. Just trued it up and it's fine.
