I'm a very tall, big rider with a Cannondale Quick hybrid, jumbo frame, custom fitted to my height. I ride at least 50 miles a week year round. (I'm in Florida.) The bike has Xero c3 wheels, size 700. That wheel has a reduced number of spokes and I break them frequently. I need a sturdier wheel and was looking for any advice from others who may have changed wheels on their Quick. I ride at 80 psi, and I love my bike's dynamics, so don't want to change the ride quality. Thanks.
