After agonizing over which dynamo hub to get for 2 weeks, I finally settled on the SP SV-8. Unfortunately, my retailer only has the 28h version in stock. I was planning on doing a 32h build, but a 32h hub would take 8 weeks to ship.

This would be paired with a DT Swiss R460 rim, and I'd run 32 or 28mm tires on it. The purpose is randonneuring, and some of the roads around here are a little rough. I weigh 170lbs, maybe 175 occasionally.

Will I be okay with 28h, or should I spring for 32? I can find another retailer with the 32h version in stock, but mine is selling 'em for $30 less than other places. (Yes, I'm cheap.)
