Compact Rotary Bicycle Pump
The design and concept of the Compact ROC pump builds upon the base technology of the Ultra pump and uses many of the same components in a longer pump to achieve even greater air volume displacement.
Early testing indicates that this version of the ROC pump will provide total volume displacement for each rotation of the crank five times of that of a single pump action of simular sized two way pumps currently avilable on the market.
RocPro anticipate that two versions of this compact pump will be avilable, the version shown below and an Urban version.
Design Specifications:-
Dimensions:- 270mm L, 38mm H and 30mm W.
Weight 350 grams
Volume displacement:- two way version 345,000mm3
