Threaded directly into a standard Schrader chuck fitting, it converts your existing pump to handle Presta valves with a secure, side-lever locking mechanism that seats firmly and holds pressure. Full metal construction means it's built to outlast the plastic alternatives that tend to crack or strip with regular use.\u003c\/p\u003e\n\n\u003cp\u003eWhere it earns its keep is on the valves that give other chucks trouble. It seals on valves as short as 10mm — including deep-section disc wheels and aero rims where only a sliver of valve is accessible. You lock it in place with the lever rather than relying on friction alone, which means a consistent seal every time regardless of valve depth or angle.\u003c\/p\u003e\n\n\u003ch3\u003eSilca 'Hiro' Side-Lever Locking Presta Chuck Specs at a Glance\u003c\/h3\u003e\n\u003cul class=\"specs_at_a_glance\"\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCompatibility:\u003c\/strong\u003e Presta valves; threads into Schrader chuck fitting\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMinimum valve engagement:\u003c\/strong\u003e 10mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLocking mechanism:\u003c\/strong\u003e Side-lever lock\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eConstruction:\u003c\/strong\u003e Full metal\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUse cases:\u003c\/strong\u003e Short valves, disc wheels, deep-section aero rims\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/div\u003e","brand":"Silca","offers":[{"title":"Default Title","offer_id":43705660637228,"sku":"AM-PU-CHU-ASY-006","price":70.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0608\/7684\/9196\/files\/silca-hiro-side-lever-locking-presta-chuck-1330378.jpg?v=1771297156","url":"https:\/\/ricycles.com\/products\/silca-hiro-side-lever-locking-presta-chuck","provider":"RA Cycles","version":"1.0","type":"link"}
