go on holiday, maybe alpe d'huez, ride it, fall in love with cycling all over again,
THIS. I just recently upgraded to a Cervelo RS (Giro D'Italia Edition) from an older Scott CR1 and the difference is huge despite the RS being a "low end" offering from Cervelo. At this point I know that the engine needs more work and the bike begs to be ridden and doesn't hold me back. With that in mind if I had extra $ and time I would go and ride in Europe in a heart beat. An experience like that will provide you with far more joy and memories than any frame or bike you can purchase. And lets be honest... at some point, even the new frame you will purchase will get old and you will "need" something better and newer. Go and experience cycling from its roots and enjoy the jaw dropping scenery, food and culture!
