Surly Disc Trucker thru-axle fork 700c, black, FK1479

Surly fork. Needs from your bike: Wheel size (ISO bead seat), Steerer tube, Front axle spacing, Brake mount, front, Fitted front tyre width, Approved replacement fork axle-to-crown length, Approved replacement fork offset, Minimum required fork steerer length, Approved replacement fork assembly interface and Fitted front rotor diameter.

The Surly Disc Trucker thru-axle fork 700c, black, FK1479 is a fork (component). It requires 10 things of a bike — Wheel size (ISO bead seat), Steerer tube, Front axle spacing, Brake mount, front, Fitted front tyre width, Approved replacement fork axle-to-crown length, Approved replacement fork offset, Minimum required fork steerer length, Approved replacement fork assembly interface and Fitted front rotor diameter — read from Surly. On every bike page its verdict is computed from those requirements against the bike's cited facts: when a fact is missing the answer is "unknown", never a guess.

Requires — Wheel size (ISO bead seat)	700c / 29" (ISO 622)
Requires — Steerer tube	1-1/8" straight threadless
Requires — Front axle spacing	Thru-axle, 100 × 12 mm
Requires — Brake mount, front	Rear-standard flat mount on a fork (Surly Disc Trucker)
Requires — Fitted front tyre width	≤ 47 mm
Requires — Approved replacement fork axle-to-crown length	390 mm
Requires — Approved replacement fork offset	45 mm
Requires — Minimum required fork steerer length	≤ 350 mm
Requires — Approved replacement fork assembly interface	Surly Disc Trucker 700c thru-axle fork, 390 mm axle-to-crown / 45 mm offset
Requires — Fitted front rotor diameter	140 mm

Steerer tube, Front axle spacing, Brake mount, front, Fitted front tyre width, Approved replacement fork axle-to-crown length, Approved replacement fork offset, Minimum required fork steerer length, Approved replacement fork assembly interface and Fitted front rotor diameter are safety-critical: a wrong answer could hurt you, so we say "fits" only when the bike's fact is confirmed by two independent sources. With one source the honest answer is "unknown"; with none it is "unknown — safety-critical".
