|Custom built wheels for CX||Cima Coppi|
Dec 13, 2001 10:48 AM
I am planning on building up my own wheels for my future CX bike, and I have some lacing questions for you experts. I already have the hubs (Campy Chorus 9/10, 32 hole), and I'm seriously considering using Ambrosio Futura deep section rims, but this is not set in stone.
Should I stick with old reliable, and lace the spokes 3X on the front and back, or is there any benefit to trying some unconventional lacing methods? I was thinking maybe 2X on the front, and 3X drive side/radial non-drive side on the rear.
Also, I'm planning on using DT 14/15 DB spokes for the build. Would I be more wise to use straight 14 gauge spokes instead? This set of wheels will be strictly used for CX and will be raced on.
As always, your input is greatly appreciated.

|I would go 14g 3X, still the strongest pattern out there. I did read on Sheldon Browns site that 14/15 spokes are actually stronger than strait 14g, but I dont know if that is true. I do a lot of singltrack as well as the usual cross stuff so strength is my #1 goal in a set of wheels. I dont think weight would be much of a difference.|

|Joe Young, who built my road wheels, explained to me that shock passed through the wheel toward the hub is absorbed more efficiently along a double butted spoke vs. a straight guage spoke. He clarified this by saying this is really only true for a properly built and tensioned wheel.

|if you want strong, get 36 holers and buld 4x with CXP type profile rim|

|Go 14/15 DB with a 3x pattern for strength and durability. DB spokes allow the rim a more natural flex so each impact is dispersed over a greater area hence the wheel can suffer greater abuse. Think of it this way if you where to throw a billard ball and a hard rubber ball against a concrete wall which one is most likely to chip or crack? The harder stiffer one will. The point of impact lies in a more concentrated area is more likely to fail. The rubber ball will deform slightly allowing the impact energy to spread over a larger surface with less force in anyone point. This may not be so scientific but gets the point across. Some of the coolest peaple too discuss this topic with are the tech people at DT and Wheelsmith. They can talk your ears off for hours on end. BTW if you plan to use alloy nipples then go with DT spokes and nipples . The alloy nips from DT last longer and do not deform as quickly as wheelsmith when you have to apply force to a seized nipple. The Wheelsmith nipples tend to be rather soft.|| |
