going from 2cross to radial, ok for hub?(9 posts)

going from 2cross to radial, ok for hub?Woof the dog
Nov 1, 2001 5:30 AM
2cross front wheel, these are my racing wheels and figured that i just want radial. I know there is no advantage, but what wouldn't you do for the yuppiness factor? its a dura ace hub. I heard its not good to rebuild with different lacing patterns, and I already know durace will not warrantie the hub if i build it up radially. I am 130 lbs so I don't think I will have a problem with riding radial.
So what do you think?

Thank you

What do you expect to gain by going from 2x to radial? You probably don't want to do it on a DA hub - try it with a higher flange hub.

It sounds to me like you understand that there are risks and that you aren't expecting any great benefits. In other words, you're going into this with realistic expectations. Style away man, I'd estimate the odds of dire consequences to be low.

By the way, What difference does high flange hubs make relative to radial laceing?

that radial lacing on ANY of there hubs should never be done. Never.
Besides, all you'll do is:
1) Create a new stress riser on the flange where the old spoke worked it's way into the metal
2) Have a wheel that rides MUCH harsher than it used to, and
3) Eventually you will rip a spoke hole out of the flange.
All of this to save what? 10 grams?? Leave your watch at home and save even more weight!!

I've had two hubs- both forged- fail on me as a result of radial lacing, I've seen many more, and most bike shops can produce examples of failed hubs, so I'd say it isn't as rare a failure as is sometimes implied.
Your weight isn't particularly significant- the fatigue is more due to the fact that the load is cyclic, than of any great magnitude. Light riders break just as many spokes and hubs as heavy ones.

That said, you obviously know it's a bit risky, and you aren't going to go pointing fingers if it does fail, so- as somebody else said- go crazy if you want. Mind you, on an aesthetic note, isn't radial spoking a bit... well... passé, these days?

You'll blow up the hub flange - guaranteed. First, as you know it's not designed for it, second you've already stressed the flange with a different lacing pattern. It's really akin to bending the coat hanger too many times. Finally you're going to make an investment in time and spokes and still only have one set of wheels when you're done - for a little more cash you can have two sets of wheels and you don't have to unlace the old wheels. When the relaced set fails you're then going to be forced to make the investmetn in the new parts anyway. It's sort of like the Fram oil filter commercial - pay me now, or pay me later, but you're going to pay.

You'll probably do it anyway, but if your smart you'll get a new set of hubs approved for radial lacing experiments. Read Jobst Brandt if you want some more advice on the subject.
Can I flip the question around then ??flybyvine

I have a Record front hub build radially. I know the same issues as the DA one above but that was the way the bike was built second hand with Ultegra and I am a cheap bastard that wanted to re-use the spokes. BUT...

Can a switch the lacing to 2x or 3x ? I too have heard the arguements that you shouldn't switch the lacing patterns. Is 2x or 3x better given the exisiting radial stress patterns ?

With all due respect to greasy's concern about hub flange stresses, I'd be more worried about the little furrows that the old spokes wore into the hub concentrating all of the stess on a tiny area of your new spokes.

I just read your responses, turned around to look at my bike and said "hell with it, I will ride it just like this" You guys convinced me, and you.....you in particular, Greezly Monkey, you scared me near death. I don't think I really have time and money to mess around with this project, although I was really thinking about it lately. Guess whats next on the list? Selle Italia SLR. Thanx all

Sincerely
