So, after getting a flat yesterday in my tubular, I've decided to build a clincher wheel set.

I need to run a 700c in the rear and a 26'' in front.
I will be using Campy Record High Flange Pista Hubs, 28H in the front and 24H in the rear.
I think I will be going with Deep V's, front and rear.

Now, what spokes would you guys recommend and what lengths do I need. Considering the fact that I'm running two wheel sizes. I've never built a wheel set before, so this is all new to me.

Thanks,

Steve

Hi. This nifty excel file will help you figure out the spoke lengths you need... https://www.damonrinard.com/spocalc.htm

dude, why don't you just buy some decent tubular tires and watch where you ride?
all you have to do is carry a spare tire and if you ride with a bag then it's no big deal.
just put two coats of glue on your spare tire and let it dry before you wrap it up, carry it with you then when you flat, you just swap the spare on and pump it up and ride.
i rode around for 2 weeks on a spare like that. it's perfectly fine. just don't corner like you're leading the pack in a crit.

Also, one last piece of information you need is the cross pattern you plan plan on using. I assume 3 cross. That excel spreadsheet should be your best friend.

Thanks everyone for the info.

As for continuing to run tubulars, I think I'm going to save the rims and build a new wheel set when I can find a decently priced pair of hubs. The thing is that tubular tires run $100 (Pista, Continental TrackPro, Vittoria Pista Ceta CS, Hutchinson Comp, etc) and I'm on a college budget and can't afford to replace them that often.

Any recommendations on spoke brand/type?

you shouldn't ride a pista tire on the street.
try a conti sprinter or sprinter gatorskin. they ride ok, roll pretty good and are pretty damn durable...most shops they are gonna cost you $50 though i would guess.
you can find them for about $40 online...

the vittoria evo corsa cx are real nice riding tires too.

if i were you i would keep the wheelset you have tubular and just build a cheap clincher wheelset...but whatever.

sapim double butted or DT swiss competition spokes are good.
