I've read some threads re: weight training and cycling and have been convinced that it doesn't help performance on the bike except for short duration efforts. However if one leg is significantly stronger than the other, how important is it to build the strength in the weaker leg? Let me also say that the strength imbalance doesn't "seem" to affect my riding ability in a negative way although I can't say for sure since this is such a long standing condition. Thanks in advance for the help.
