I've done a cursory forum search and it seems that spokes breaking on the rear wheel is correlated to the rider's weight. I'm 6'2" and hover around 275 lbs. I'm a power lifter and I expect to maintain this weight or get heavier. I've popped 2 spokes in as many weeks, so I thought I'd get some opinions from the community.

As stated in the post title, my bike is a Jamis Citizen. I generally ride to work and back (6 miles, 7 days a week), and put in another 80 recreational miles weekly on a paved trail. From what I've read here, it doesn't sound like I'm doing anything the bike wasn't built to handle. Do I need to look into a new rear wheel? A different bike?
