Spoke size.....(4 posts)

Spoke size.....Rob
Dec 3, 2001 3:28 PM
Ok, Now I have a good question. What size/gauge spoke should I use for my wheelsets (Dura-Ace 1st generation 8-spd hubs, Velocity Aero rims, Trek 400 Cr-mo frame/fork): 14 strait, 14/15/14, or 15 strait? I weigh 220 and will be riding average pavement, some hills. I just built my first set of wheels for the mountain bike, and I used 14strait w/brass nipples but I know they will see some more abuse than the roady. What is the best combo?

Tough call as the 14 ga. spokes will build a stiffer wheel, but butted spokes tend to have better fatigue resistance as they stretch in the butted section and are less likely to stress crack at the thread or elbow. Volumes have been written, and I will probably get flamed for being so basic, but you are probably better off with butted spokes in 32 or 36 hole, 3 cross. The velocity is a pretty stiff rim, so you will get the best of all worlds with, stiffness and fatigue resistance. And I would definitely use brass nipples.

I also prefer 14mm long nipples instead of 12, I think they protect the thread end of the spoke better, and if there is any bend in the spoke at all near the nipple the longer nipple will help stress the spoke further away from the thread. Very small difference, but we have done this for years with great results.

I will check with Kyoshi(Japanese LBS owner) about getting the DB spokes as I will have him build the wheels up. I am fixed with 32 hole as I am re-using the old hubs I have(wore the rims out) and I am just waiting for the rims to get here in the mail. Thanks for the tip. I'll let you know how it goes.

I've been building my own wheels for a few years and have built using both 14 and 14/15 db. The db seem easier to true and seem to stay true longer. I'm sure there is a scientific explanation for this, but I don't know it. Just my experience.
