Just 15 cm long, weighing only 77 grammes and with a capacity of more than 160 psi/7bar, the innovative Supernova Pump is an extremely small and compact air pump. The key features of this high-performance and easy-to-use pump are the new operating method and its effort saving characteristics.Comes complete with Presta valve adaptor (woods not supplied) & mounting bracket for bottle-cage mounts - One of the few pumps that when installed to the bike don't detract from its looks.
