{"product_id":"ritchey-ultra-frameset","title":"Ritchey Ultra Frameset","description":"Ritchey: \u003cp\u003eIf there’s one thing Tom knows, it’s dirt. When he first designed the Ultra he knew it would appeal to riders who demand specific ride characteristics and dirt slaying only he could deliver- and that was in the 1980s! Good design withstands the test of time, and the latest iteration of the Ultra is a prime example. Like its predecessor from 30 years prior, the new Ultra occupies a unique ride space from cross-country riders looking to get rowdy and go big to enduro riders lusting for some all-mountain shredding.\u003cbr\u003e \u003c\/p\u003e \u003cp\u003eDesigned around a 120mm travel fork and super stable Boost 148 spacing, most of the fun is in the wheels. Designed to accommodate 29\" or 27.5\" wheels, the Ultra is highly versatile. Throw on some 29s for some trail-smashing XC riding, or saddle up some 27.5+ for some serious no-holds-barred shredding. The Ultra is a rough and rugged trail master that doesn’t know when to quit.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003eCompatible with 27.5 x 2.8 and 29 x 2.4 tires\u003c\/li\u003e\n\u003cli\u003eInternal routing for a dropper post\u003c\/li\u003e\n\u003cli\u003eBoost 148x12 rear spacing\u003c\/li\u003e\n\u003c\/ul\u003e \u003cp\u003e\u003cspan style=\"text-decoration: underline;\"\u003e\u003cstrong\u003eTECH SPECS\u003cbr\u003e\u003c\/strong\u003e\u003c\/span\u003e\u003cbr\u003e\u003cstrong\u003eMaterial\u003c\/strong\u003e heat-treated, triple-butted Ritchey Logic steel tubing - TIG welded\u003cbr\u003eUltra-light forged and machined tapered head tube\u003cbr\u003eElectrophoretic Deposition (ED Coat) treated for corrosion resistance\u003cbr\u003e\u003cstrong\u003eHeadset\u003c\/strong\u003e integrated - 1.5” tapered (upper IS42\/28.6 | lower IS52\/40)\u003cbr\u003e\u003cstrong\u003eHeadset upper bearing\u003c\/strong\u003e 41.8mm OD \/ IS42\/28.6 (S.H.I.S.)\u003cbr\u003e\u003cstrong\u003eHeadset lower bearing\u003c\/strong\u003e 51.9mm OD \/ IS52\/40 (S.H.I.S.)\u003cbr\u003e\u003cstrong\u003eSeat tube clamp size\u003c\/strong\u003e 33.1mm (2.5Nm max for derailleur clamps and chain guides)\u003cbr\u003e30.9mm seat tube with stealth dropper routing and replaceable seat collar\u003cbr\u003e\u003cstrong\u003eBottom bracket\u003c\/strong\u003e 73mm - English threaded\u003cbr\u003eBOOST cranks must be used for proper 52mm chainline\u003cbr\u003e\u003cstrong\u003eCrankset maximum ring size\u003c\/strong\u003e 38T single - 26\/36T double \u003cbr\u003eDesigned for 1X or 2X chainrings (Side Swing front derailleur required for double)\u003cbr\u003e\u003cstrong\u003eRecommended tire size\u003c\/strong\u003e 27.5x2.4 (2.8 max) or 29x2.25 (2.4 max) - tire size varies by rim and tire manufacturer\u003cbr\u003e\u003cstrong\u003ePost-mount rear brake\u003c\/strong\u003e 160mm (180mm max - adaptors available separately)\u003cbr\u003e\u003cstrong\u003eSizes\u003c\/strong\u003e S (15\") \/ M (17\") \/ L (19\") \/ XL (20.5\")\u003cbr\u003e\u003cstrong\u003eWeight\u003c\/strong\u003e 2,380g (M\/17\")\u003cbr\u003e\u003cstrong\u003eColour\u003c\/strong\u003e Mustard\u003cbr\u003eBOOST 148mm spacing (12mm alloy thru-axle included)\u003cbr\u003eOptimized for 120mm (BOOST) suspension travel fork or 500mm axle-crown rigid fork\u003cbr\u003eExternal cable routing\u003cbr\u003eReplaceable stainless-steel derailleur hanger\u003c\/p\u003e","brand":"Ritchey","offers":[{"title":"Yellow \/ S \/ No Type","offer_id":53322002628872,"sku":"RT97452007027","price":999.99,"currency_code":"EUR","in_stock":false},{"title":"Yellow \/ M \/ No Type","offer_id":53322002661640,"sku":"RT97452007028","price":999.99,"currency_code":"EUR","in_stock":false},{"title":"Yellow \/ L \/ No Type","offer_id":53322002694408,"sku":"RT97452007029","price":999.99,"currency_code":"EUR","in_stock":false},{"title":"Yellow \/ Xl \/ No Type","offer_id":53322002727176,"sku":"RT97452007030","price":999.99,"currency_code":"EUR","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1022\/8275\/6360\/files\/ritchey-ultra-frameset-5749698.jpg?v=1779879672","url":"https:\/\/aerolux.ie\/products\/ritchey-ultra-frameset","provider":"Aerolux","version":"1.0","type":"link"}
