Unless those PRs were set during sprints in which you went out solo, rather than doing much of the distance drafting, then it's the group dynamics that made you faster.
To say that this ride and your other PRs were all set during a group ride misses the point. If the group rode harder this time, then you got the benefit. If the group as a whole is speeding up as the riders get more fit later in the season, you got the benefit.
It may not be about bike, but in a group ride, it's the engines, not the engine - assuming that yours is good enough to keep from getting dropped.
