You're right, many people do deep squats and are perfectly fine, however what I meant to say is that when your doing 5000-plus repetitions on the bike every ride, why would it be worth the risk of injury to do leg exercises at the gym when your doing them on the bike already? I know they inherently train different muscles in a different way, but don't you think the low impact nature of cycling is a much better choice, such a better choice that it isn't worth jeopardizing with the aggresive nature of weight training. Any worthwhile mass-building routine for lower body is based around a 12-15 repetition set, being that which most effectively stimulates hypertrophy. That is alot more impact that pedaling a bike, putting you at a very high risk of eventually developing an injury, believe me I've done it, even under supervision on a NCAA track team.
One last thing for all you cyclists that don't know it already, eat PROTEIN!! everyone focuses on not bonking and eating enough carbs. But we forget that the muscles we use for hours on end are made of protein, and they catabolise with use.
