Dude, read the massive thread on lifting. Your question above will be answered by many by saying "none." ...
For example, we have a leg press machine at my gym that is leveraged in such a way as to make 315 lbs for 8 reps very tough, while I've been on other (that look very similar) and been able to a whole lot heavier. ...
There is only one good benchmark for leg power. Squats, to a uniform depth (say honestly parallel to the floor, which few people do), with feet no wider than maybe hip width apart, with the back kept bolt upright. Actually, I guess a hack squat machine would be an even better test because it enforces this very same form. ...
Well I read most of that thread but I didn't go through it in depth. In my very well informed opinion, the basic principle is simple from a physical point of view: if you combine your normal cycling and other aerobic training, weight lifting is not detrimental. Your heart gets stronger and your lean muslce mass increases at the same time. (the weight training won't affect your heart and lungs much) And cycling unlike running etc. involves very difficult climbing and high levels of resistance, in which case more muscle power is needed.
Doing TOO MUCH weight training is detrimental to endurance athletes because your heart - which will remain the same - will have to power a heavier frame, but combining the two isn't. If Lance Armstrong does it, like the other pros do, it must work. He does it to regain lean muscle mass which he loses during the racing season and build functional strength. But anyway this is besides the point because that's what that other thread is about.
As for the leg press, obviously with different machines the difficulty will vary, that was talking specifically about a seated leg press. The machines like that are all quite similar, and I suppose maybe you had done a tougher workout before the one time it was easier. The difference between a seated/reclined/inclined will obviously be much bigger.
As for hack squats they work your quads don't they, and from what all the experts say the leg press works your quads the best. Well Chris Carmichael says that the leg press (seated) has got all the benefits of a squat without the risks/potential damage. That's why he says Lance never does squats.
But okay I'm getting off track again here, all I wanted to know at the end of the day was which groups of muscles are most important to cycling (i.e. gastrocnemius, quadriceps etc.). I suppose your opinion on how to train your legs may be different, but if it works for me I won't complain. (e.g. if you wanted to train your quads differently [and in a far tougher way!] get on one of those flat "leg press" ergos which are a bit like recumbant bikes, crank up the resistance to max and there you go, similar effect) So for example should I spend more time working my quads, calves etc?
Thanks for your help.
(BTW that site was for sprinting, but it should still be useful as a comparative measure.)
