I recommend investing in a hand-built wheelset (or at least rear wheel). I've been commuting since 2003 (I was 205 lbs). Now, 260. (I know most people lose weight when they start a 20 mile daily commute not gain 55 pounds.) As my weight crept up over those years, the spoke breaking/truing issue on the rear wheel became a big problem across 3 different bikes (especially the inappropriate-for-a-daily-commuter-over-160-pounds stock wheelset on Trek Portland). I finally bought strongest possible wheelset from Peter White. Although I only have about 1500 miles on them, I feel confident that these wheels will outlive me without breaking a spoke or needed to be trued.
