That's progress. Silca frame fit pumps were made for racing in the
days when solo tire changes were still part of the sport. Racers
wanted a pump that was ultimately light and had a substantial swept
volume. Since wheel changes became standard, only recreational
bicyclists need frame fit pumps and the Silca, that required a bit of
strength and skill, was no longer in demand.
I think you have heard of valve stems breaking, pistons shooting
across the road, and inability to get more than 60 psi. The result is
heavier pumps with 50% smaller pistons and short enough to fit
anywhere. That these pumps take 200 or more strokes is no concern
compared to the problems encountered with the Silca pump. I have
stockpiled a few Silcas and am sad to have seen them pass into
oblivion. RIP along with good derailleur chains.
