{"product_id":"transition-bottlerocket-frame-2027","title":"Transition Bottlerocket Frame 2027","description":"\u003cp\u003eThe Bottlerocket Frame is a starting point for a freeride build with a clear purpose: jumps, steep lines and repeated bike-park laps. Its aluminium chassis is dedicated to 27.5-inch wheels at both ends and comes with a Marzocchi Bomber Air shock in the 225 x 70mm configuration, giving 180mm of rear travel.\u003c\/p\u003e\u003cp\u003eC.H.I.P.S. lets you choose suspension progression independently of the higher or lower geometry position. That is useful if you want to change the support through the travel without automatically changing the bike's stance. The bolt-on S.A.L.S.A. rear dropouts provide a further tuning option, with longer 5mm and 10mm versions sold separately.\u003c\/p\u003e\u003cp\u003eThe frame combines a gravity-cast bottom-bracket section with forged rocker and chainstay-yoke parts. Replaceable rubber downtube guards deal with rock strikes and shuttle contact, and the threaded bottom bracket and UDH hanger give the build familiar service standards.\u003c\/p\u003e\u003cp\u003eThis is a frame and shock, not a complete bike. A headset is not included. The platform also supports a longer-travel dual-crown configuration, but the supplied shock configuration is 180mm; choose any alternative shock and fork against Transition's compatibility requirements.\u003c\/p\u003e\u003ch3\u003eGeometry\u003c\/h3\u003e\u003cp\u003eManufacturer platform geometry.
