1:bicycle manufacturers innovation->bicycle racers'demand
2:bicycle manufacturers innovation is limited->standard for competition decided by authorities
Thus:
bicycle racers' original demand does not follow authorities standards but racers choose to follow,what means bicycle manufacturers innovation is limited for no one would be interested in it. The only assumption is the second part. E is irrelevant in that whether the authorities keep informed or not is not concerned about the consequence that orginal text offered.
