I don't know if I can link to the Wattage forum here, but if I can, give this a read. Otherwise go on theere and read the post titled "strength training impairs endurance muscle." Lots of cool stuff.

On an anecdotal note, I've lifted this year more for general strength (and aesthetics... I'm not vain...). Feel better, can do my job better. Cycling be damned, I'm happier as a result.
