Brother Cycles Big Bro Steel Fork
The Brother Big Bro Steel Fork is a rigid fork for adventure and mountain-bike builds. Designed for the Big Bro, its 483mm axle-to-crown length approximates a sagged 100mm suspension fork, making the geometry a key consideration when using it on another frame.
Choose Boost 110mm or non-Boost 100mm hub spacing. Both versions provide clearance for large-volume tyres and use an included 15mm thru axle, but the non-Boost version does not have the two rack fittings at the top front of the legs. Check the mounting arrangement against the rack and luggage you plan to use.
