Its aggressive tread, enhanced sidewall protection and race-focused construction deliver the grip and confidence needed for mud, sand, loose rock and mixed trail terrain.\u003c\/p\u003e\u003cp\u003eWhile the RCG-1 prioritises outright speed and the RCG-3 offers all-round versatility, the RCG-4 is the choice when traction, puncture protection and control matter most.\u003c\/p\u003e\u003ch2\u003eBuilt for Noosa and Sunshine Coast Adventures\u003c\/h2\u003e\u003cp\u003eThe RCG-4 is particularly well suited to adventurous gravel riding around Noosa and the Sunshine Coast, where hinterland routes can include loose gravel, sandy sections, rocky forest tracks and steep, shifting surfaces.\u003c\/p\u003e\u003cp\u003eIt is a strong choice for exploring rougher routes around Kin Kin, Pomona, Cooran and Cooroy, along with bike-appropriate sections of the \u003ca href=\"https:\/\/www.noosa.qld.gov.au\/Services-and-Facilities\/Parks-and-Facilities\/Noosa-Biosphere-Trails\"\u003eNoosa Biosphere Trails\u003c\/a\u003e. When conditions become loose or unpredictable, the RCG-4 provides the additional grip and protection needed to keep the bike composed.\u003c\/p\u003e\u003cp\u003eThe aggressive tread uses fewer but significantly larger knobs than the RCG-3. Wide spacing between the knobs helps clear sticky soil and mud instead of allowing the tread to become packed and lose traction.\u003c\/p\u003e\u003cp\u003eWider and taller knobs also place more rubber between the casing and sharp rocks. Combined with SILCA’s SealSkin bead-to-bead protection, the RCG-4 is the most heavily protected tyre in the Protocol gravel range.\u003c\/p\u003e\u003cp\u003eDespite its aggressive design, the RCG-4 retains SILCA’s performance-focused Pulsar compound and supple Race Casing. This helps balance rolling efficiency, grip and durability, allowing riders to tackle demanding terrain without making the bike feel unnecessarily slow or heavy.\u003c\/p\u003e\u003cp\u003eAvailable from Venture Cycles Noosa, the RCG-4 is an excellent choice for Sunshine Coast gravel riders heading beyond smooth roads and into rougher, more technical terrain.\u003c\/p\u003e\u003ch2\u003eWhy Choose the RCG-4?\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eSILCA’s most aggressive gravel tread\u003c\/li\u003e\n\u003cli\u003eDesigned for mud, sand and loose rock\u003c\/li\u003e\n\u003cli\u003eWidely spaced knobs help shed mud and sticky soil\u003c\/li\u003e\n\u003cli\u003eLarge shoulder knobs provide confident cornering grip\u003c\/li\u003e\n\u003cli\u003eSealSkin bead-to-bead puncture protection\u003c\/li\u003e\n\u003cli\u003eAdditional sidewall protection for rough terrain\u003c\/li\u003e\n\u003cli\u003ePulsar rubber and silica performance compound\u003c\/li\u003e\n\u003cli\u003eSupple 120 TPI Race Casing\u003c\/li\u003e\n\u003cli\u003eCarbonBead BeadLock technology\u003c\/li\u003e\n\u003cli\u003eTubeless-ready construction\u003c\/li\u003e\n\u003cli\u003eIdeal for adventurous gravel racing and mixed trail riding\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eSpecifications\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSize:\u003c\/strong\u003e 700 × 45 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eETRTO:\u003c\/strong\u003e 45-622\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCasing:\u003c\/strong\u003e 120 TPI Race Casing\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCompound:\u003c\/strong\u003e SILCA Pulsar\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePuncture protection:\u003c\/strong\u003e SealSkin bead-to-bead\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eConstruction:\u003c\/strong\u003e Tubeless ready\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eClaimed weight:\u003c\/strong\u003e 545 g\u003c\/li\u003e\n\u003cli\u003e\u003cstrong\u003eWidth measured on a 25 mm internal-width rim after 24 hours\u003c\/strong\u003e\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRecommended minimum SILCA sealant:\u003c\/strong\u003e 90 ml per tyre\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SILCA","offers":[{"title":"700 x 45","offer_id":47078308184236,"sku":null,"price":159.95,"currency_code":"AUD","in_stock":false},{"title":"700 x 50","offer_id":47078308217004,"sku":"SI\/163359","price":159.95,"currency_code":"AUD","in_stock":true},{"title":"700 x 55","offer_id":47078308249772,"sku":"SI\/163366","price":159.95,"currency_code":"AUD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0672\/1906\/2956\/files\/RCG4sidesquare_720x_91e72e5e-73d1-4706-9e59-95a8ccd12713.webp?v=1787881152","url":"https:\/\/venturecycles.com.au\/products\/silca-protocol-rcg-4-gravel-tyre-700-45-mm","provider":"Venture Cycles","version":"1.0","type":"link"}
