Well, the bike didn’t change. It fits and rides the same.
Typically a rider adapts to some degree regardless of the bike. Over time, especially time off that bike, people change. Perceptions change.
You saved up over a year to get that bike. Unless it was a complete dog, it was going to be the best thing you had ridden. You had invested too much and could easily overlook any minor flaws. I think it is human nature to do this.
You probably should take it out on the road and see if it brings back those magical moments. If it does keep it. If not, and you’re not attached to it anymore, sell it.
