{"product_id":"primer-frame","title":"Primer Frame","description":"\u003cp\u003eThe Primer is a bike built for 29 or 27.5+ wheels with geometry designed for aggressive all mountain riding. It is handbuilt in Canada by local fabricator Chris Dekerf in small batches that are painted individually for each customer.\u003c\/p\u003e\n\u003cp\u003eThe Primer uses what we would describe as our most progressive 29er geometry to date (excluding the \u003ca href=\"\/collections\/29\/products\/doctahawk\"\u003eDoctahawk\u003c\/a\u003e!), notably the short chainstays, lower than ever BB height, steep seattube with a slack head angle, low stack headtube and long front center. This combination is the most versatile 29er we've ever built.\u003c\/p\u003e\n\u003cp\u003eBuilding a frame with 27.5+ compatibility means that we had to redesign our ‘yokel’ junction to maximize the chainstay layout clearance. Incorporating a BB92 bb shell and boost dropout spacing also accommodates the most room possible for tire widths as wide as 3.0.\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e\u003cem\u003eLooking to spend a little less?

Chromoly is an abbreviation for chromium-molybdenum indicating the materials that the steel is alloyed with. The added chromium helps increase the steels hardenability and also provide some corrosion resistance. The molybdenum helps to increase the toughness of the steel. It has a high tensile strength but is also malleable which is what gives our frames their notorious ride quality and feel. Chromoly is often used when more strength is required than that of mild carbon steel. It falls under the AISI (American Iron \u0026amp; Steel Institute) 41XX designations which is where the “41” comes from. The “30” indicates it contains approximately 0.30% carbon by weight. Chromoly is much stronger than traditional 1020 steel and it has a higher strength to weight ratio and high tensile strength, which means we can use less material and achieve a product that can withstand the abuse that riders love to throw at it.\u003c\/p\u003e\n\u003cimg src=\"https:\/\/us.chromagbikes.com\/cdn\/shop\/files\/chromag-4130-steel-tubes_1c681308-8d2f-407c-924d-7fa83d9a9717.jpg?v=1678826326\" alt=\"4130\" style=\"width:100%;height:auto;\"\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\n\u003ch3\u003eKey Features\u003c\/h3\u003e\n\u003cp\u003e\u003cspan class=\"metafield-multi_line_text_field\"\u003e☛ 4130 custom drawn tubeset and CNC dropouts and yoke\u003cbr\u003e\n☛ 29\" wheel size\u003cbr\u003e\n☛ Handbuilt in Canada \u003cbr\u003e\n☛ Evolved, progressive all mountain geometry based on 160mm fork\u003c\/span\u003e\u003c\/p\u003e\n\n\u003ch3\u003eWhat's in the box\u003c\/h3\u003e\n\u003cp\u003e\u003cspan class=\"metafield-multi_line_text_field\"\u003eIf you ordered a full bike, you'll have everything you need to get rolling right away, prior to some minimal setup.\u003cbr\u003e\nFrames come with a hanger, chain stay protector and rear axle.\u003c\/span\u003e\u003c\/p\u003e\n\n\u003ch3\u003eProduct Details\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eWheel Size:\u003c\/strong\u003e 29\" or 27+\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRecommended Fork Travel:\u003c\/strong\u003e 160mm (±10mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial:\u003c\/strong\u003e 4130 Chromoly Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFrame Weight (M\/L):\u003c\/strong\u003e 6.89lbs\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHub Spacing:\u003c\/strong\u003e Boost 148mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHeadset:\u003c\/strong\u003e 44-56 Semi Integrated\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeat Clamp Size:\u003c\/strong\u003e 35mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeat Post Size:\u003c\/strong\u003e 31.6mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBB:\u003c\/strong\u003e 92mm Press Fit (PF92)*\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHanger:\u003c\/strong\u003e UDH (Included)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRear Axle:\u003c\/strong\u003e 180mm, M12 X 1.00mm - Boost 148 UDH (Included)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrake Mount:\u003c\/strong\u003e I.S.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFrame Origin:\u003c\/strong\u003e Canada\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBuilder:\u003c\/strong\u003e Chris Dekerf\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHead Angle:\u003c\/strong\u003e 64°\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFork Offset:\u003c\/strong\u003e 42MM\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeat Angle:\u003c\/strong\u003e 76°\u003c\/li\u003e\n\u003c\/ul\u003e\u003ctable border=\"1\" cellpadding=\"5\" cellspacing=\"0\"\u003e\n\u003ctbody\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e","brand":"Chromag","offers":[{"title":"CUSTOM PAINT \/ S","offer_id":47889529077814,"sku":"202-020-009","price":1890.0,"currency_code":"USD","in_stock":false},{"title":"CUSTOM PAINT \/ M","offer_id":47889529110582,"sku":"202-020-005","price":1890.0,"currency_code":"USD","in_stock":false},{"title":"CUSTOM PAINT \/ M\/L","offer_id":47889529143350,"sku":"202-020-006","price":1890.0,"currency_code":"USD","in_stock":false},{"title":"CUSTOM PAINT \/ L","offer_id":47889529176118,"sku":"202-020-007","price":1890.0,"currency_code":"USD","in_stock":false},{"title":"CUSTOM PAINT \/ XL","offer_id":47889529208886,"sku":"202-020-008","price":1890.0,"currency_code":"USD","in_stock":false},{"title":"LIGHT GREY \/ L","offer_id":47889529241654,"sku":"202-035-004","price":1890.0,"currency_code":"USD","in_stock":false},{"title":"BURGUNDY \/ M\/L","offer_id":47889529274422,"sku":"202-033-034","price":1890.0,"currency_code":"USD","in_stock":false},{"title":"PASTEL BLUE \/ M\/L","offer_id":47889529307190,"sku":"202-034-034","price":1890.0,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0650\/0715\/7302\/files\/0e6f046ae7b01bf75ed74bfc8b660dadbf942396.jpg?v=1790462298","url":"https:\/\/www.cahabacycles.com\/products\/primer-frame","provider":"Cahaba Cycles","version":"1.0","type":"link"}
