Prestacycle redesigned the Presta Head Grommet to fit to modern standards. It works so well, it was copied by others including major floor pump makers who elude to being original through clever wording. We’ve included it in every Prestaflator tool and Big Presta Head since May 2012, long before anyone else. You can always count on Prestacycle for true innovation.
Our design engages the Presta valve just below the cap threads and requires less insertion. The head is now very easy to get on and off. Our use of natural light gray color is more environmentally friendly than products made with deep color dyes. Safe for all types of Presta valves, including tubeless and tubeless-conversion valves. Will not harm newer lightweight performance valves. Fits all Prestaflator BIG Push/pull Presta heads. Also fits all Silca pump heads that use the 24.1 or 242 Gasket.
