was out on a ride today and saw a Dahon with the exact tire I wanted to buy, the marathon in 20x1.5". It sure looks like a narrow tire, especially the contact patch. I may decide to bump up to 1.75", which opens up the Road Cruisers for consideration. Can't find any reviews for that though. I assume it's a new tire.

went off-road quite a bit today, even some climbing. was really surprised how well the Friday did. Definitely want a tire that accommodates that.
