Aarg!!!!!!! I can't believe it either, but I must also agree with 53-11 for once. My circumstances are different however. I do calf lifts, leg press and 45 degree hack squat. I mainly do the weight training at the beginning through the end of base training, lower weights at first and build to the heavier stuff. I don't do too much weight training during the summer other than once a week. I winter train on a tacx I-magic machine so I can record all improvements just like on a computrainer.
The reason my circumstances are a bit different to that of an upright bike, is because I race and do long distance on a low racing recumbent. I'm always in a leg press position on the bike, so the weight training to the legs are very beneficial.
