The bike: Gary Fisher Nirvana hybrid used for daily commuting (16 miles total on mostly smooth pavement), loaded with back panniers. Also used for longer unloaded, week long touring. The symptom: broke a rear spoke at two different times with less than 1 year of riding on bike. Spoke broke at hub attachment. Spokes are black painted and look a tiny bit thinner than the stainless ones that were used for replacements. Should the whole rear wheel be relaced with new spokes by LBS or get a new wheel with more spokes? Current wheel has 32 spokes. Never used off-road, most roads pretty smooth. Rider weight 145, load weight 20. Usually run stock tires at 100 lbs pressure. Same thing happened on a prior Gary Fisher of similar model that was stolen.
