Either a road conversion or a frame designed for single speed. You'll want it drilled to take both front and rear brakes, which a true track frame probably won't be. I'd ditch the idea for the Ellipses too, you'll wear off the anodizing within a week. If you want Mavic I'd stump up for some handbuilt wheels instead with CXP33 or Open Pro rims
