I didnt think about that. Try a regular dual pivot in the back, and see if it clears, if it does, roll out. if not, put the universal in the rear with some decent pads, and a dual pivot tektro up front.
If this were for my girl/children:
SA 3-5 speed in the rear laced with ukai or similar 27"
Tektro front, whatever I could fit on the back with some koolstops.
CST 27" tires and heavy duty tubes.
