Ksyrium lacing question(7 posts)

Ksyrium lacing questionmootsdude
Mar 25, 2002 7:10 PM
Does anyone know why mavic laces the rear drive side radially and the non-drive side 2x on the ksyrium? This is opposite of all other wheels and seems to go against the laws of physics and wheel building theory. I've riden the ksyriums 4k miles and they're still as round and true as the first day. Great wheels!!
It's the hub...g-money

They purposely designed the hub to allow a more even overall spoke tension. Basically the non-drive side of a rear wheel helps hold the thing together. There really isn't much structurally with the non drive side. With Mavic's rear hub, the wheel is centered more thus allowing them to evenly tension (mostly) both sides. The hub is what allows them to radial lace the thing. Not too many... if any, other hub would allow the tension nec to radial lace a drive side. The tension on the Mavic spokes is whopping... It works... I love mine...

I think the SPOX did the same thing... but i don`t know why for sure(Maybe to do with evening tension) ? Do you race alot ,or have you stressed them to your recolection because i am thinking of getting them, but last weekend in Central Park ,i saw a guy who had 1 of the spokes unhook in a sprint(somehow it floped around, but never broke, so he just put it back), and he was not really a heavy guy(maybe 150-160)? Other than that though, everyone seems to love them? they are light though huh?

Always wondered about that too.. But it does seem to work. Mine have held up better than any other set of wheels I have ever owned.
Because of the thick spokesJS

The hub flange on the cross spoked side is so thick that it would be impossible to use on the drive side, you'd end up with some reverse dish on the driveside. Thats why SPOX do the same thing.

The hub flange is made thick to enable the 'reverse' spoking with the radial on the drive side. Chicken or egg?

A rear wheel MUST have spokes crossing and attaching to the hub at a tangent on one side or the other to keep the spokes from winding up under pedal forces. Typically this is on the drive side what with the chain being on that side. However, because of the thick spoke ends this cross side flange on the Ksyrium is very thick making it impossible(to have on the drive side), you'd end up with some wacked out inverted dish, not good. Take a long hard look at these wheels, you'll figure out what I'm talking about. Again, SPOX thick spoke ends also necessitate this.
