I do fullbody workouts twice a week, basically hit every bodypart once with one exercise consisting of 4 sets with enough weight to get 8-12 reps each set. Rest 30 seconds between sets. Legs are about 20 reps per set. And do lots of core work.
Lifting weights for your legs in season can definitely hurt your performanace on the bike. For me, there is no way I can do the intensity on the bike during the season if I lift weights.
So effort in the gym for your legs is going to limit the effort you can put forth on the bike, and thereby limit your improvement.
For example, typical week for me right now might be competitive group ride Tuesday, endurance miles wednesday, intervals thursday, race Sat and Sunday. No way I can do 4 quality days in a week, and also lift.
For the OP's question, a light upper boddy/core routine is a different story.
