None of the 11-28 cassettes/freewheels on the Sheldon Brown Gear Calculator have a 17 or a 19 tooth gear.

10 Speed None
9 Speed 11-12-13-14-16-18-21-24-28
8 Speed 11-12-14-16-18-21-24-28
7 Speed 11-13-15-18-21-24-28

The 52-19 combination would be about 73 gear inches. I know that I could climb a 1.25 mile, 7.5% grade on that gearing but it would be hard. I'd have to stand the entire way and I could not do it with 35lbs of gear on my back.
