Well, the 3900 is history.
Now I'm thinking of putting The Diego on the market. I've learned that I enjoy the road bike experience BUT The Diego is probably not going to work, long-term. I just don't think I'll ever get it dialed in.
So, I guess it's time to put it on the chopping block. I'm going to keep the Cypress as my back-up bike, possibly a touring bike, and all-round beater bike, although it's hardly in "beater" condition. But it is more fun to ride for short errands than my Coasters, Click and Clack. And I'd sell the coasters but my daughter would have my hide, so for now, they stay.
