The package includes the Toray, Nippon Graphite Pan-Based Fiber carbon frame, matching Factor SARANA carbon fork, FSA SL-K SB0 seatpost, and Black Inc integrated barstem; wheels and a groupset are sold separately, and the frame is built for electronic shifting only.\u003c\/p\u003e\n\u003cp\u003eFactor developed the SARANA with Canadian ultra racer and 2025 Unbound XL champion Rob Britton, testing prototypes across British Columbia's varied terrain to learn how a bike holds composure as a rider fatigues over hundreds of miles. The result is a leaf-spring seat-stay design — dropped stays paired with an offset seat tube — that flexes vertically to smooth rough-road vibration while keeping the rear end laterally stiff for efficient power transfer. That same seat tube offset is what let Factor hold 425mm chainstays across every frame size, a detail specific to how this frame is engineered rather than something scaled by size.\u003c\/p\u003e\n\u003ch4\u003e\u003cstrong\u003eWho It's For\u003c\/strong\u003e\u003c\/h4\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cp\u003eRiders training for or racing multi-day, self-supported ultra-distance gravel events, in the mold of Unbound XL\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003eRiders who want a race-oriented frameset they'll spec themselves, since it's sold without wheels or a groupset\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003eRiders who value sustained comfort and control over hundreds of miles as much as outright stiffness\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003eRiders who need mechanical shifting, or want a complete, ready-to-ride bike, should look elsewhere — this frameset is compatible with electronic groupsets only\u003c\/p\u003e\n\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003e\u003cstrong\u003eWhat to Look For\u003c\/strong\u003e\u003c\/h4\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003ch4\u003e\n\u003cstrong\u003eElectronic shifting only\u003c\/strong\u003e — this frame does not support mechanical drivetrains, so confirm your groupset choice before ordering\u003c\/h4\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003ch4\u003e\n\u003cstrong\u003eBottom bracket standard\u003c\/strong\u003e — CeramicSpeed T47A WIDE aluminum cups, with CeramicSpeed bearings available for both DUB and 24mm spindles, so match this to your crankset\u003c\/h4\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003ch4\u003e\n\u003cstrong\u003eDropper post compatibility\u003c\/strong\u003e — the FSA SL-K SB0 seatpost accepts a 30.9mm dropper, worth factoring in if you want that option for technical descents\u003c\/h4\u003e\n\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003e\u003cstrong\u003eKey Features\u003c\/strong\u003e\u003c\/h4\u003e\n\u003cp\u003eThe \u003cstrong\u003eToray, Nippon Graphite Pan-Based Fiber carbon frame\u003c\/strong\u003e and matching \u003cstrong\u003eFactor SARANA carbon fork\u003c\/strong\u003e form a race-tuned platform engineered specifically for ultra-distance gravel, not adapted from a road or cross-country design.
