Innovative features include an ultra compact rotary design that produces a large pumped air volume, giving quicker inflation times and better ergonomics that making tyre inflation easier and reduced chance of breaking valve stems. The ROC pump exploits the mechanical advantages of an innovative and new patented mechanical device that converts a single rotary action into multiple linear movements. ROC pumps are smaller and deliver at least twice as much air volume per stroke than the current best mini pump design on the market. This will give far shorter tyre inflation times with the benefit of less time fixing punctures and giving more time cycling. A cosmetic prototype of the ultra compact pump and working model of the internal mechanism has been recently produced and the manufacture a fully functional prototype to fully test the pump’s operation against the expected specifications in currently underway.
