Your 26, 27.5, or 29-inch mountain bike receives a significant weight cut, enabling faster pedal strokes and looser handling on steep gradients. The TPU build holds firm under load while shaving grams that make a noticeable difference on single-track climbs.\u003c\/p\u003e \u003ch2\u003eBenefits \u0026amp; Tips\u003c\/h2\u003e \u003cul\u003e\n\u003cli\u003e\n\u003cb\u003eYou set the stage correctly.\u003c\/b\u003e Slide the tube into your tire first and add air gently until it rounds out.

Expanding air without rim constraints causes irreversible damage to the internal structure.\u003c\/p\u003e \u003cp\u003eBefore pressing air, turn the Schrader valve inward toward the center of the wheel circle. Bending the stem early protects the valve core and prevents kinks during installation.\u003c\/p\u003e \u003cp\u003eHonor the 5 bar limit strictly. Exceeding maximum pressure risks the tire bead unlocking from your rim, creating sudden loss of control. Temperature changes affect you too; expect roughly a 1% pressure jump for every 3°C warm-up while riding.\u003c\/p\u003e \u003cp\u003eAll electronic and mechanical equipment, devices and machines sold by InterCyprus to EU countries are CE certified and carry a two year warranty.\u003c\/p\u003e \u003cp\u003eServing trail riders with verified quality and honest parts sourcing since 2002 — intercyprus.com earns your confidence on every order.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"InterCyprus Trading Ltd","offers":[{"title":"1PCS 26X2.0-2.8C \/ 45mm \/ Presta Valve","offer_id":55532872499542,"sku":"1005008034973437-1PCS 26X2.0-2.8C-45mm-Presta Valve","price":22.59,"currency_code":"EUR","in_stock":true},{"title":"2PCS 26X2.0-2.8C \/ 45mm \/ Presta Valve","offer_id":55532872532310,"sku":"1005008034973437-2PCS 26X2.0-2.8C-45mm-Presta Valve","price":34.67,"currency_code":"EUR","in_stock":true},{"title":"1PCS 27.5X2.0-2.8C \/ 45mm \/ Presta Valve","offer_id":55532872565078,"sku":"1005008034973437-1PCS 27.5X2.0-2.8C-45mm-Presta Valve","price":22.4,"currency_code":"EUR","in_stock":true},{"title":"2PCS 27.5X2.0-2.8C \/ 45mm \/ Presta Valve","offer_id":55532872597846,"sku":"1005008034973437-2PCS 27.5X2.0-2.8C-45mm-Presta Valve","price":34.67,"currency_code":"EUR","in_stock":true},{"title":"1PCS 29X1.95-2.8C \/ 45mm \/ Presta Valve","offer_id":55532872630614,"sku":"1005008034973437-1PCS 29X1.95-2.8C-45mm-Presta Valve","price":20.41,"currency_code":"EUR","in_stock":true},{"title":"2PCS 29X1.95-2.8C \/ 45mm \/ Presta Valve","offer_id":55532872663382,"sku":"1005008034973437-2PCS 29X1.95-2.8C-45mm-Presta Valve","price":35.19,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0530\/0604\/1274\/files\/S7105b535b9664b7aa8f50a713fed8ea6a.webp?v=1790709965","url":"https:\/\/www.intercyprus.com\/products\/gustavo-mtb-bike-tpu-inner-tube-ultralight-mountain-bicycle-tire-tubes-26-27-5-29-x-1-95-2-8-presta-valve-45mm","provider":"InterCyprus Trading Ltd","version":"1.0","type":"link"}
