Did you find a 650c front wheel? I have a HED 3 trispoke front that I don't need, I just use the rear. I bought the pair off of eBay. Today, 2 years later, (since I never planned to use the front) I noticed the front has a dent in the rim. I would let the buyer bend it back so they know exactly what transpires (rather than me bending it back and saying the rim is perfect).
Email me if interested. I can send pictures.
