I think if you read back over my posts you will see that I didn't say weights are unequivocally unhelpful for sprinting. However, to get a benefit from weights to crossover to cycling you need to either:
-Train at the specific joint angles and muscular velocities attained in cycling. (Basically not possible - except on the bike). OR
-Get hypertrophy (bigger muscles). This isn't always that easy and requires a fair commitment to the weight room, such that it isn't worth it for a roadie. The tradeoff of metabolic fitness via interference effect and the raw physiological and weight changes are further strong negatives.
