Some regard it as unnecessary. Indeed, a bicycle can be ridden perfectly safely without a rim nut. It is however helpful when attaching the pump connector, as particularly when the pressure is low the valve may fall inside the rim. With some rims there may be a rattle if the valve is not fixed.\u003cbr\u003eThe rim nut must only be tightened by hand. Never tighten the rim nut with pliers, as this can lead to tube damage. \u003cbr\u003eThis Inner tube is compatible with the following tyres:\u003cbr\u003eBrompton Kojak 32-349 \/ 16 x 1 1\/4 inch folding tyre with reflective sidewall\u003cbr\u003eSchwalbe Kojak 32-349 \/ 16 x 1 1\/4 inch wired tyre\u003cbr\u003eSchwalbe Marathon 16 x 1.35 tyre\u003cbr\u003eSchwalbe Marathon plus 16 x 1.35 tyre\u003cbr\u003eBrompton Green \/ Kevlar tyre \u003cbr\u003eBicycle compatiblity includes:\u003cbr\u003eBrompton folding bikes\u003cbr\u003eDahon curve 16 folding bike\u003cbr\u003eMezzo D10 16 folding bike\u003cbr\u003eand many more\u003c\/p\u003e","brand":"Schwalbe Korea","offers":[{"title":"Default Title","offer_id":44972757385286,"sku":"TU2657","price":10.0,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0728\/0328\/7110\/files\/av4.jpg?v=1777697029","url":"https:\/\/bicyclehero.com\/products\/schwalbe-bicycle-tube-av4-16-18-schrader","provider":"BicycleHero","version":"1.0","type":"link"}
