{"product_id":"the-trail-blank-carbon-29er-boost-frame","title":"The Trail Blank | FR-701 Full Carbon 29er Boost Mountain Frame","description":"\u003cdiv class=\"product-narrative\"\u003e\n\u003cp\u003e\u003cstrong\u003eEvery mountain bike is an argument about the frame. Everything bolted to it is a detail.\u003c\/strong\u003e Geometry decides how the bike behaves when the trail stops being predictable, and material decides what the rider feels while it happens. Builders and riders who understand that spend their money on the chassis first and the components second.\u003c\/p\u003e\n\u003cp\u003eThe FR-701 is a full carbon fibre hardtail frame drawn around 29-inch wheels with plus-tyre clearance, using Toray carbon in a UD matte finish. The numbers are the ones that matter at the trailhead: 1250 grams give or take 50 in the 17-inch size, a 148mm rear width on the boost standard, BB92 bottom bracket shell, and a 31.6mm seatpost with a 37mm clamp. The head tube is 1.5 inch reduced to a 1-1\/8 inch tapered steerer, integrated, which is what allows a modern fork to be fitted without adapters.\u003c\/p\u003e\n\u003cp\u003eClearance for 29 by 3.25 inch tyres is not a marketing figure. It changes where the bike can be ridden: higher volume means lower pressure, lower pressure means grip on loose rock and traction in sand, and both mean less fatigue in the hands and shoulders over a long descent. The band-mount front derailleur fitting keeps a two-by drivetrain possible for riders who want range rather than a single ring.\u003c\/p\u003e\n\u003cp\u003eThree sizes, 17, 19 and 21 inch, cover most adult riders, and the frame arrives as a frame: no fork, no wheels, no shortcuts. It is the starting point of a build, which is exactly what it should be.\u003c\/p\u003e\n\u003cp style=\"margin-top:16px;\"\u003e\u003cem\u003eThe frame is the part of the bike that remembers the

style=\"line-height:1.75;margin:0;\"\u003eThe home builder replacing a tired alloy frame is the main buyer, usually with a groupset and wheels already chosen and a frame as the last decision. Shops and small builders use it for customer builds where the frame has to be predictable across three sizes. Bikepacking riders choose the plus-tyre clearance deliberately, because a 29 by 3.0 tyre at low pressure turns a rigid hardtail into something that can be ridden for days. Riders who expect a full suspension feel from a hardtail will be disappointed by physics rather than by this frame.
