I have a rear wheel I am going to rebuild. The spokes appear to me to be straight 13G - they are huge. The bike came to me with this wheel, but the rim is bent (was ridable for some time). I bought a new rim and thought I'd just switch everything straight across, except with new spoke nipples. Would I be better off buying butted spokes and not reusing the huge ones. The bike is used as a townie for shopping, commuting, etc. and sometimes carries heavy loads. Wheel is 700C Campagnolo Omega Strada Hardox with Sachs 7X3 hub and 4x pattern. Spoke calculator gives me lengths of 303.5 and 301.8 but I will measure the old ones to be sure if I go with new spokes. I can get 302 length either 2.0/1.7 or 2.0/1.8, would those work?
