In addition for somebody whos new to the sport wouldn't weight training help accelerate the process having little to no base muscle? I mean my legs are still pretty small and I can' timagine weigh lifting won't benefit someone like me, I'm sure there is a platoing affect for it though.
I started cycling in august last year, rode moderate to heavily from aug-oct, then the cold and snow came and I went to the trainer and gym from oct-dec and we got a 60+ degree day in Dec and I took the bik eout and felt amazing.
