Lacing Pattern(16 posts)

I'm in the process of building a new bike and am trying to decide on the wheels. Because I'm trying to strike a balance between performance, reliability and economics, I'm going with Campy Record hubs and Mavic Open Pro rims. However, what lacing pattern would you choose? I'm a recreational rider and put in several thousand miles per year. I'm 5'6" and weigh about 150 lbs.

My current bike has DA hubs laced 3X to 32H Mavic OPs with 14-15G spokes. These have performed just fine but I was just wondering if there is a lacing pattern that would result in something slightly lighter and more aerodynamic that would be just as reliable. Or is there something else out there that's priced around the same that is just as good?

Thanks for your help.

32 3x 14/15 guage is the answer you will get. I honestly think its overkill for a 150 pounder but they will definitely be tough if you build em that way.

Differences in aerodynamics are moot. Radial looks sweet tho, but other than being a fashion statement, there are few definable differences.

Campy hubs are not warrenteed against breakage if you Radially lace them.
Causes a catastrophic failure. Very Bad Thing.
2 cross in front, triple in rear. Looks good.

granted he did say which hubs he is using, but there are hubs out there warranteed for anything and some specifically designed for radial lacing.

And no recorded incidence of such failures, that I know of. That's why most reputable LBS's (including Excel Sports) will readily build radially-laced front wheels on hubs where it "voids the warranty."

I gladly did it for the spiffy looks.

I think that you're in denile.

Radially laced hubs definitely put more stress on the flange, and definitely lead to failure, sometimes. I've seen it happen, but it isn't common, maybe 5% of hubs laced radially will fail- it isn't a high enough number to really worry about.
5% sounds reasonable to me.Spoke Wrench

As a wheelbuilder, however, if one out of every 20 customers came back to me wanting a new wheel, I'd have to change my procedures. I've built some radial wheels, but the guys who have them all know that if the eyelets crack, it's on them.

As long as you're sticking with 32H the lacing pattern won't effect the weight (same number of spokes and all). The Record gubs are great and so are the Open Pros. The 3x is pretty much the standard and is what I've built all my wheels to be. Since you're not a heavy rider though, you could radially lace the front and do a 2x drive and radial static side on your rear. The spokes would be slightly shorter so maybe lighter (though I doubt you could actually measure the difference). But the overall wheel would have a narrower profile so it would be a little more aerodynamic.

I have a radial front with a Chorus hub and have had no problems. A radial wheel will be slightly lighter than one with crossed spokes but I did not notice the difference. I did notice that the front end was laterally stiffer though. This makes out of the saddle climbing feel better though.

Go with 15/16 gauge. At your weight and a 32 hole, there's no reason to use 14/15. Weight savings for radial are very minor, aero effects are even less. 3X, 2X, even 1X would work, and as noted, Campy hubs are not covered under warranty if you radially spoke. They may hold up fine, but if they fail, you're SOL. There is one true feature to radial spoking - it makes it easier to clean your spokes with a rag.

At your weight and 32 spokes, go DT revolutions.

Thank you all for your suggestions and useful information. Since there was some mention that given my weight of 150 lbs, does it make sense to consider 28H OPs instead of 32H?

If so, are 15-16g spokes still viable or should I switch to 14-15g?

Thanks again.

A lot is going to depend on your riding and pedaling style. You might want to consider a 28 up front, keeping the 32 rear. Kerry and juanmore... mention lighter spokes which is a good way to reduce weight w/o sacrificing reliability. In addition to the DT revolutions, I'd look into Sapim Lasers and Xrays. The latter are bladed but don't require the hubs to be slotted and are also lighter than the revolutions or Lasers.

You also might want to consider alloy nipples although they have their downside in building and in that they can bind from corrosion onto the spoke making adjustment difficult.

Just though I would add a couple of comments.

Rear: 32 hole, 14/15 spokes and brass nipples on the drive side, non-drive side can get away with Revolutions since the tension is quite low there. If you favor long term durability, get all brass nipples.

Front: 32 hole with Revolution spokes will work fine at your weight. Again, brass nipples if you want added durability. Aluminum will work fine although you will likely round some out as you true them over the years. You could go 28 hole for the front although you will not gain all that much weight savings.

Oh, and lastly, 3X spoke pattern for both wheel. Radial lacing is for SHOW, not for GO.
