just because many people might do something, doesn't mean it's correct. until fairly recently power meters weren't readily available. however, now that they are people who do endurance cycle racing (e.g., TT, RR, MTB XC, Track endurance, etc) can see how useless weights would be to increase performance. previously (i.e., pre power meters), where fatigue may have set in temporarily, e.g., when climbing, people can/could easily confuse the feelings of fatigue and changes in intracellular pH with a lack of strength. Clearly, this isn't the case and is easily proved by either training, or altering haematological parameters.
Except in some instances, cyclists are not limited by strength and don't need to do weight training to increase cycle performance.
we know that you don't!
this is totally unlikely to happen, no elite pro is likely to start some intervention that according to the majority of the available research and first principles isn't going to help.
additionally, we know that Mayo can generate enough power to win (e.g., Ventoux TT @ Dauphine Libere).
But it isn't, as clearly we know that doing weights isn't as good at improving ECP as cycling itself. Several of us have explained this to you over and over, have you dropped a weight on your head!!?
