Another neat solution for a concealed pump on the TSR2 is this a Lezyne Pressure Drive M Pump. Good for up to 120PSI though its hard work after the first 100PSI which takes about 125-150 pumps!
Comes with a reversable Presta/Schrader valve hose that fits neatly in the end.

This shows the width of the widest point. Although it looks like the rubber bungs are the widest point it is in fact the bottom of the pump handle. The specs quote 22.5 mm wide, clearly not the case. Anyway this is why I purchased it because at this width, its an interference fit if you pop it into a cut down version of the supplied plastic bag and then put it into the seat post on the TSR2
