I am having some trouble finding a spoke calculator that has the data for my rim/hub combo. I am building a wheelset using formula 32H hubs to Sun Assault 700C rims. can anyone help me out with this? I know alot of people have experience with formula hubs, maybe you can at least give me the measurements form one?(flange hole circle diameter and flange spacing) ALso, does anyone have experience with these Assault rims?

I appreciate the link, but I actually know HOW to take the measurements... I just wanted to order my spokes along with the hubs and rims.. therefore, I dont have the items in hand. I was hoping that someone knew where I could find these values, or for the off chance that someone built this same combo and knew the spoke length.

Hey, unless you *really* want to build up wheels of your own, I would just recommend getting Nashbar's CXP 22 track wheelset (formula hubs) for $135 ($150-10% off coupon). That's what I would have done, but they were out of stock when I was buyin stuff...

second google hit for "sun assault ERD" and it's also right on the road rim list at sun's website.
the hub specs are on IRO's site.

You made me feel like an idiot, but thanks for doing so.
