It is new bike time. I was waiting on the new Casseroll (which is finally out), but I am also now digging the new Vaya. One of my goals this year is to ride to San Diego from North Orange County by the end of the summer and by then be in century riding shape. I do 30-40 miles now. So, not quite up to many of your standards, but I am adding more miles.
Anyhow, looking at the Vaya (55cm): http://salsacycles.com/bikes/vaya/ and the Casseroll (53cm): http://salsacycles.com/bikes/casseroll/ I don't know enough to understand the differences in geometry.
Is there anything that stands out with the Vaya that would make it not long ride friendly? Does a straight fork ride different from a curved fork? I like the look of the curved fork better.
They both have 3 water bottle cages, room for fat tires with fenders, steel, etc. The LBS doesn't stock them, but can order them. I want to order before sold out. They sld out on me last year.
