all the competative cyclists i know don't do lower body work to increase strength (and size/weight). they just do endurance... and they have scrawny legs. it would seem somewhat counterproductive to do heavy weight training, there is a completely different mechanism in strength sports (weight lifting, racing, etc.) and endurance sports (like cycling, or long distance running).
if you're talking about some sort of sprint, that's different though.
generally though if you're training just for strength, you lose a little endurance. case in point: a buddy of mine stopped doing high rep work (press 225 X times for example), and his max for a mid-level weight dropped dramatically. his bp increased from probably 275 to 350, but his 225 reps dropped from ~20-25 to 14. It's just activating different fibers in the muscle.
