N-1
Just sold my Trek 8.5DS (Dual Sport)
I bought it last year thinking it would be ride trails and use is as an around town bike for when I didn't want to have to get fully dressed to ride my Emonda. But after a year I barely rode it and decided I wanted to get a Cross bike for road and trail. The DS has sat in my garage since getting the CX bike so I figured it was time to cut my losses and sell it.
I also figured that the Fall was a good time to sell, so I posted it on Craigslist and 24 hours later it's gone. I did lose $200 from the purchase price, but it was a lesson learned.
So for now N=2 and i'm OK with that.
