Radially laced Chorus hubs(8 posts)

Radially laced Chorus hubsE-ticket
Jun 28, 2001 5:48 PM
I just bought a used bike set up with campy chorus hubs on open pros. The front is laced radially (14/15/14). The Campy web site states explicitly that these hubs are not to be laced radially. Does anyone have experience with this setup? Is it dangerous? Should I have it re-laced?

There will not be a danger to continue riding the chorus hub w/ a radial laced wheel, its more that Campy does not want to liable for anything that might happen. A radial laced wheel is stiffer than a cross patterned wheel, so the ride will be harsher. Also, because of Campy's claim, the hub is now out of warantee. You should be fine on it as long as you like the ride. If its too harsh, then consider rebuilding it.
I gotta go with Campy on this one...TJeanloz

There can be no doubt that a radial pattern puts more stress on the hub flanges. Enough to cause failure? Possibly. Would you want your front wheel to fail in such a manner? Probably not. Would I go to the effort of re-lacing it- no. I wouldn't build a set new like that; but it's not such a problem that it needs to be changed at once.

That's the exact Jobst comment I was trying to find, but couldn't, and was about to misquote! Well done on your efficiency Doug...
Never rebuilt a wheel with a different patternonrhodes

I've been told by a wheel building guru friend of mine that you should NEVER rebuild a wheel with a different lacing pattern after building it up a different way. In other words, if you build it up 2x, every time you rebuild the wheel it should now be rebuilt 2x. He claimed that the amount of force that tensioning up a wheel puts on hub is quite severe and messing around with pulling it in all different directions multiple times can be a really bad idea.

The only effect radal lacing will have as others have said is to increase the likelihood of the hub flange breaking out. I have seen the results of this a few times... twice on my own wheels for which I thought the 'cool factor' was worth the risk. It is still not likely enough that you should worry about the wheels in use, however.
The stiffness of the wheel is no different from one built with any other kind of lacing pattern.
The spoke heads will already have formed the spoke holes of the hub to their shape, so don't have the same hubs relaced to a different pattern: increased spoke failures will be the likely result.

I just had a new bike built with Chorus t.out. The front wheel was specifiaclly laced radially. It feels great on the corners and hasn't caused me a problem, and if it did I doubt the flanges would give totally and the wheel colapse - If I end up in intensive care don't quote me!!!

Campag are just worried about product liability claims, rather than personal injury.

I gather the european pros generally ride radially spoked wheels?
