Presta valve bicycle pumps

Presta

— a type of nipple used in high performance bicycle wheels, particularly road and cyclocross. Also known as SV or FV. Can also be installed in tubeless tyres. Such a nipple is thinner than the popular "car" Schrader, it has a diameter of about 6 mm and a valve that protrudes noticeably outward. The valve is quite fragile and can break when inaccurately inflated or using a low-quality pump, so it is often made replaceable.

Note that pumps for Presta can also be used with Dunlop type nipples (see relevant paragraph).
