Description

Brother Cycles' dedicated adventure frame, the Big Bro, is supremely tough and hungry for challenging trails. Whether you’re running a lightweight bikepacking setup, front and rear panniers for a fully loaded ’round-the-world’ tour or just stripped back to thrash some forest trails the Big Bro can handle it

The frame is made out of tough 4130 double butted cro-mo tubing and comes with a 100mm suspension corrected fork, both with corrosion resistant ED coating applied. The Big Bro features Boost spacing which means there’s clearance for big 27.5 x 3″ tyres or 29 x 2.6″ tyres if you’d prefer to go with a 29er setup. It features stealth dropper routing, rack mounts, bottle mounts on the seat tube, down tube and under the down tube for an extra bottle or storage. The forks also feature triple bottle mounts to fit further bottle cages or Anything Cages. S-bend chainstays with replaceable alloy thru axle sliding dropouts allow for geared or singlespeed setups
