{"product_id":"brother-cycles-big-bro-frameset","title":"Brother Cycles Big Bro Frameset 2024","description":"\u003cp\u003eOur all purpose, tough as nails 29er\/27.5+ adventure frame; designed to take you well off the beaten track and beyond. Whether you’re running a lightweight bikepacking setup, stripped back to thrash some forest trails or even front and rear panniers for a ’round-the-world’ tour the Big Bro can handle it.\u003c\/p\u003e \u003cp\u003eThe frame is made out of tough 4130 double butted cro-mo tubing and comes with a 100mm suspension corrected fork, both with corrosion resistant ED coating applied. There’s clearance for big 29 x 2.4″ tyres or up to 3 inch tyres if you’d prefer to go 27.5+. It features stealth dropper routing, rack mounts, bottle mounts on the seat tube, down tube and under the down tube for an extra bottle or storage. The forks also feature triple bottle mounts to fit further bottle cages or Anything Cages. S-bend chainstays with replaceable alloy thru axle sliding dropouts allow for geared or singlespeed setups.\u003c\/p\u003e \u003cp\u003eLike all Brother products the Big Bro has been rigorously tested out in the real world – we took prototypes across the South Downs, through Snowdonia National Park and up to the Scottish Highlands. The Big Bro has since completed two of the worlds toughest bikepacking endurance races – the 4,418km Tour Divide from Canada to Mexico and the 1,710km Silk Road Mountain Race in Kyrgyzstan.\u003c\/p\u003e \u003cp\u003e\u003cstrong\u003eFEATURES\u003c\/strong\u003e\u003c\/p\u003e \u003cp\u003eTubing: - 4130 Chromoly steel - double-butted main triangle, ED coated\u003cbr\u003eBrake compatibility; 51mm IS disc brake mount, 180mm max rotor size\u003cbr\u003eDropouts: Boost 12x148mm thru axle (included)\u003cbr\u003eSeat post diameter: 30.9mm\u003cbr\u003eSeat clamp diameter: 33.1mm (included)\u003cbr\u003eHeadset: 44mm, SHIS ZS44\/28.6 upper, EC44\/40 lower (not included)\u003cbr\u003eFront derailleur clamp diameter: 34.9 mm high direct-mount (adapter available separately)\u003cbr\u003eBottom bracket shell: 73mm bottom bracket, ISO threaded\u003cbr\u003eMaximum tyre clearance: 29\" x 2.6\", 27.5\" x 3.0\" (note: not all drivetrains allow for these maximum tyre clearances)\u003cbr\u003eFork : 4130 Chromoly tapered unicrown fork, ED coated. 15x110mm Boost thru axle (included)\u003cbr\u003eFull-length cable housing guides for derailleurs and brakes\u003cbr\u003e3 sets bottle cage mounts on all sizes\u003cbr\u003eChainring clearance: 44-30t double, 38t single\u003cbr\u003eWeight: medium (18\") frame 2.60kg, fork (300mm steerer) 1.37kg\u003cbr\u003eTested to ISO 4210 MTB standard\u003c\/p\u003e","brand":"Brother Cycles","offers":[{"title":"Cobalt Blue \/ Small - 16","offer_id":57810930794822,"sku":"210000034942","price":1.99,"currency_code":"GBP","in_stock":true},{"title":"Cobalt Blue \/ Medium - 18","offer_id":57810930827590,"sku":"210000034943","price":1.99,"currency_code":"GBP","in_stock":true},{"title":"Cobalt Blue \/ Large - 20","offer_id":57810930860358,"sku":"210000034944","price":1.99,"currency_code":"GBP","in_stock":true},{"title":"Cobalt Blue \/ XLarge - 22","offer_id":57810930893126,"sku":"210000034945","price":1.99,"currency_code":"GBP","in_stock":true},{"title":"Yellow \/ Small - 16","offer_id":57810930925894,"sku":"210000022200","price":1.99,"currency_code":"GBP","in_stock":true},{"title":"Yellow \/ Medium - 18","offer_id":57810930958662,"sku":"210000022199","price":1.99,"currency_code":"GBP","in_stock":true},{"title":"Yellow \/ Large - 20","offer_id":57810930991430,"sku":"210000022198","price":1.99,"currency_code":"GBP","in_stock":true},{"title":"Yellow \/ XLarge - 22","offer_id":57810931024198,"sku":"210000022197","price":1.99,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1022\/6037\/5878\/files\/bb21yl1.jpg?v=1794009621","url":"https:\/\/estio.shop\/products\/brother-cycles-big-bro-frameset","provider":"Estio","version":"1.0","type":"link"}
