total spoke-replacing newbie question here: if i'm replacing a spoke, does it have to the same kind of spoke or does it just have to be the same size? i have those flat kindsa aerodynamic spokes on a wheel - can i replace a broken one with just a plain-vanilla good old fashioned round spoke?

most likely your talking about a road bike, but on a bmx bike i think it just has to be the same size(width and length)
i hope that helps

The only critical dimension in a spoke is length. Once that is taken care of the spoke
gauge is the next parameter, and if this is a 'permanent' substitution it would be
better to get a heavier rather than lighter gauge spoke, assuming the wheel to be
less than 32 spoke count and in particular if it is a drive side rear wheel spoke where
tension is highest. Steve

Spoke length is the only key dimension you need consider.
I have a 20 spoke radial front wheel with 19 blades and 1 double butted SS spoke.

thanks folks...
