A note on racks : how big are your shoes? the 42.5cm chainstays of BF designs can make it difficult to get a rack that gives you good heel clearance, go with tubus cosmo rear rack, you can get adapters that will allow for attaching it to rear stays and you can get the panniers lower with the second horizontal bar. The BF rack (have one, don't like) doesnt need to put the load so high, even on a 20" bike. Any popular panniers ortlieb+vaude+carradice will still hang with enough ground clearance, and also the tubus design is narrower width at top which will angle bag away from and over the rear derailleur. Also go with shimano shadow rear deraiulleur to have less protusion.

Any word still on when swift will do steel frameset? Seemed like it was in the works for a while back then, but no more.
