The Yeti Cycles SB115 C-Series C2 in Anthracite is the definitive "Downcountry" machine. It blurs the line between a razor-sharp cross-country racer and a rowdy trail bike. Born on the high-alpine trails of Colorado, the SB115 is designed for riders who want to crush climbs like an XC pro but still attack the descents with the confidence of a much bigger bike.
The C2 build sits in the "sweet spot" of the Yeti lineup. It utilizes their C-Series Carbon (a slightly heavier but equally stiff layup compared to the top-tier TURQ series) and pairs it with a workhorse component spec that prioritizes performance reliability. The Anthracite finish is a stealthy, matte dark grey—understated, menacing, and timeless.
Frameset & Suspension (The Switch Infinity Magic)
Frame: C/Series Carbon Fiber, 115mm travel, Switch Infinity suspension architecture, Boost 148mm spacing.
Fork: Fox Performance 34, 130mm travel. (The "34" stanchions offer the perfect balance of stiffness and weight for aggressive trail riding).
Shock: Fox Performance Float DPS. (Tuned specifically for the SB115 to provide a firm pedalling platform that opens up instantly for hits).
Switch Infinity: This is Yeti’s "secret sauce." As the bike moves through its travel, the pivot point moves up for anti-squat (pedalling efficiency) and then switches direction to move down (plushness). It’s why a 115mm bike feels like it has 140mm of travel.
Colour: Anthracite.
Drivetrain & Brakes (SRAM GX Ecosystem)
Shifter: SRAM GX Eagle, 12-speed.
Rear Derailleur: SRAM GX Eagle, 12-speed.
Crankset: SRAM GX Eagle, 30T (DUB).
Cassette: SRAM GX Eagle 1275, 10-52T. (The massive 520% range ensures you can spin up the steepest fire roads to earn your descents).
Chain: SRAM GX Eagle.
Brakes: SRAM G2 R 4-Piston Hydraulic Disc.
Rotors: SRAM Centerline, 180mm (Front & Rear). (4-piston calipers on a short-travel bike is a statement: this bike is meant to go fast).
Wheels & Tires
Wheelset: DT Swiss M1900, 30mm internal width. (Bombproof aluminium wheels with DT’s legendary ratchet system hubs).
Front Tire: Maxxis Minion DHF, 2.5", EXO casing. (The gold standard for front-end grip).
Rear Tire: Maxxis Aggressor, 2.3", EXO casing. (Fast-rolling center tread with aggressive side knobs for cornering).
Setup: Tubeless ready
Key Performance Features
Geometry: With a 130mm fork, the head angle sits at a slack (for XC) 67.6 degrees, while the seat tube angle is steep enough to keep you centered on climbs. It’s agile in tight switchbacks but stable at speed.
C-Series Carbon: While the "TURQ" frames are lighter, the C-Series uses the exact same stiffness profile and testing standards. You get the same legendary Yeti ride quality for a better price, with only a marginal weight penalty (approx. 200g).
Fox Transfer Post: This build comes with a reliable Fox Transfer dropper post (travel varies by size), essential for getting the saddle out of the way on technical descents.
Short Travel, Big Attitude: Do not let the "115mm" rear travel fool you. The Switch Infinity platform provides excellent mid-stroke support, meaning the bike doesn't wallow. It encourages you to pop off roots and pump through berms rather than just plowing through them.
