|How should I build up a Stiff set of tubular wheels?||853|

|I decided on the rim - (Thanks for that advice)But now
my LBS mechanic recommends against building up a set. He says that the stiffest wheels out there would be the Boutique wheels, any regular build would be flimsy. I know you guys don't believe this. Tell me how to build an extremly stiff wheelset for racing. I was planning on using the Velocity Escape rims w/ Dura-Ace hubs. Now all I need is a spoke spec and count. I was thinking 28h front radial,32h rear 3x using 14/15db spokes.
I am a strong sprinter type if that helps.

|You may want to go with straight 14 ga. on the drive side so that the tension on the nondrive side can be increased to prevent the nipples from coming loose.
I theory straight pull spokes can take more tension and can produce very stiff wheels, but the boutique wheels ussally reduce the spoke count so you loose the stiffness you gained with the straight pull spokes.
PS: I prefer a cross pattern on the front. I have both and the radial front feels mushy and wobbly when I am up out of the saddle and leaning forward over the bars. I doubt if I am loosing energy it just feels a little too loose for my taste. No problem when I am in the saddle or when I am not leaning forward.

|If you're a sprinter type, DO NOT go radial in the front unless these are JRA wheels. (or you're riding DeepVs, CXP30s, or the like. I could have missed that...)
I built a pair of D/A/Ritchey Aero wheels radial in the front. Tried doing some short almost standing starts on them once. That was once too many times! Really torquing on the radial wheel made it flex all over the place.
If I'm out for an LSD ride its a great wheel.
|Use 2 cross for the front. The weight penalty is minimal... nm.||russw19|

|I wouldn't build it any other way.
with front trick is to put heads in, it makes the stiffest front wheel possible. Many builders do opposite; and sometimes fork gets into way/not enough clearance.
On rear building half radial/heads out left side helps to reduce dishing and equalizes tension. It also prevents breakage of non-drive leading spokes in J-bent. For big "strong sprinter type" I'd consider using 14G trailing spokes on drive side but it may be too much to ask from your builder.
Beware, radial lacing voids warranty on Shimano hubs. Never had been an issue.
