The valves are made from \u003cstrong\u003e7075 series aluminium\u003c\/strong\u003e, an ultra-light, very strong alloy that keeps rotating weight to a minimum, and have a wide internal bore for fast airflow when inflating and unobstructed sealant injection.\u003c\/p\u003e\u003ch3\u003e4 mm hex socket and integrated core remover\u003c\/h3\u003e\u003cp\u003eThe kit includes two valves complete with black cores, ultralight caps, rubber bases, O-rings and lock nuts, plus two sets of alternative rubber bases to ensure compatibility with the rim profile, two spare cores and a purple cap with integrated core remover. The 4 mm hex socket at the base allows simple, leak-free installation.\u003c\/p\u003e\u003ch3\u003eFitting and choosing the length\u003c\/h3\u003e\u003cp\u003eChoose the right base: round for rounded rim beds, square for flat ones. Insert the valve into the hole from the outside, fit the O-ring and screw on the lock nut; holding the valve with the 4 mm hex key from the inside, tighten the nut by hand without overdoing it. For the length, allow at least 15 mm beyond the rim profile.\u003c\/p\u003e\u003ch3\u003eTechnical specifications\u003c\/h3\u003e\u003cul\u003e\u003cli\u003e\u003cstrong\u003eMaterial\u003c\/strong\u003e: 7075 series aluminium.\u003c\/li\u003e\u003cli\u003e\u003cstrong\u003eInstallation\u003c\/strong\u003e: 4 mm hex socket.\u003c\/li\u003e\u003cli\u003e\u003cstrong\u003eCap\u003c\/strong\u003e: purple with integrated core remover.\u003c\/li\u003e\u003cli\u003e\u003cstrong\u003eCompatibility\u003c\/strong\u003e: all wheels, rims and inserts.\u003c\/li\u003e\u003cli\u003e\u003cstrong\u003eAirflow\u003c\/strong\u003e: wide internal bore.\u003c\/li\u003e\u003cli\u003e\u003cstrong\u003eContents\u003c\/strong\u003e: 2 complete valves with caps, bases, O-rings and lock nuts.\u003c\/li\u003e\u003cli\u003e\u003cstrong\u003eSpares\u003c\/strong\u003e: 2 sets of alternative bases and 2 cores.\u003c\/li\u003e\u003cli\u003e\u003cstrong\u003eChoosing the length\u003c\/strong\u003e: at least 15 mm beyond the rim.\u003c\/li\u003e\u003c\/ul\u003e\u003ch3\u003eFrequently asked questions\u003c\/h3\u003e\u003ch4\u003eHow do I choose the right length?\u003c\/h4\u003e\u003cp\u003eTake the rim profile height plus at least 15 mm, so the valve protrudes enough to attach the pump easily.\u003c\/p\u003e\u003ch4\u003eWhich rubber base should I use?\u003c\/h4\u003e\u003cp\u003eWith rounded rim beds use the round base of the correct width, with flat rims the square one. The base must be pushed all the way down the valve.\u003c\/p\u003e\u003ch4\u003eIs it normal for the O-ring to protrude?\u003c\/h4\u003e\u003cp\u003eYes, Dynamic explains that a slight bulge of the O-ring indicates an airtight seal. Tighten the nut by hand, without overdoing it, to avoid air leaks.\u003c\/p\u003e\u003ch4\u003eWhat is the purple cap for?\u003c\/h4\u003e\u003cp\u003eIt has an integrated core remover: it lets you remove the core to top up the sealant or unclog the valve without extra tools. The cap can be fitted on one of the two wheels instead of the black one.\u003c\/p\u003e","brand":"Dynamic","offers":[{"title":"44 mm \/ Black","offer_id":55075878601050,"sku":"DY-093","price":27.99,"currency_code":"EUR","in_stock":true},{"title":"60 mm \/ Black","offer_id":55075878633818,"sku":"DY-094","price":28.99,"currency_code":"EUR","in_stock":true},{"title":"80 mm \/ Black","offer_id":55075878666586,"sku":"DY-095","price":29.99,"currency_code":"EUR","in_stock":true},{"title":"100 mm \/ Black","offer_id":55075878699354,"sku":"DY-098","price":31.99,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0532\/7139\/6534\/files\/Valvole-tubeless-Dynamic-Barkeeper-All4cycling-34.jpg?v=1792868569","url":"https:\/\/maisoncalyx.shop\/en\/products\/valvole-tubeless-dynamic-barkeeper","provider":"All4cycling ","version":"1.0","type":"link"}
