Tubus Racks. For those who don't know the difference between the two models, I've posted pics below.
BUT, as mentioned, it will only work on forks with pass-through mid-fork rack brazeons (one on each side of the fork leg). I got the Tara because my Co-Motion Nor'wester only has the braze-ons on the outside of the fork legs, which is a bummer. If I ever get the bike repainted I'll have them add the extra pass-through braze-ons.

I wasn't aware of the pass-through mid fork requirements, which my bike doesn't have. Guess it's going to be the Nova. Thanks for the heads up!
