Different sizes give different feel... But it's not only the bore on the radial pump that matters, but also the stroke...
For example, the bigger the stroke is, then you get more progressivity in your braking...For road use, the best combination is 19x20 (borexstroke)... If you want the pump for racing you can go 19x18 or even 19x16(extreme)...
