This is the closest I've come to n-1 mode:
I've been toying with the idea of getting a new Pursuit as a retirement gift to myself (and soon, hopefully!) and while the initial thought was to get one of the Pursuit Pure Road models to replace my Cannondale Synapse, I realized that since I only ride unpaved surfaces very infrequently and won't be commuting anymore (by definition ...did I mention I hope it happens soon?) I could instead get a Pursuit Supple Road and then have that one bike replace both my Synapse and my CAADX.
So n-1 might happen.
