Talked to the Xootr folks today. No disc tabs. Also talked to BF. They will do discs, although they encouraged me to consider rim brakes for the rear because that's one less rotor to get bent in a folding/packing situation. But they will do it, and they will install a braze-on that allows a standard rack to clear the disc caliper without using a standoff -- very nice. Extremely knowledgeable and helpful (consistent with everything I've ever heard about Bike Friday).

I have to admit, I'm leaning towards the Swift (the steel one from CAT/HPM, which does include discs as an option). Not just because the price would likely be quite a bit lower (though still a bit over $1k). There's a cleverness and elegance about the Swift's design that really appeals to me, and I really like the opinions I'm reading so far about the riding experience. I'm just starting to read the Swift thread and have a long ways to go.

Of course the real decision will come after the test ride. Sometime in the next few weeks I'll find a way to get myself down to Eugene for test rides of both bikes. Being able test ride both bikes in the same day, and see how I like their folding mechanisms firsthand, will be fantastic.
