I just tore down a set of CB350 wheels, and Yamaha XS650 wheels. I'm going to lace the XS rims on the CB hubs. The spokes from the CB are okay looking, and I was wondering if they could be reused. I have built plenty of BMX wheels but always used new spokes, because they strech. Do these spokes stretch like BMX rims? What would you guys do... Spend the cash or skimp?
