We say...

Just a perfectly designed, simple, steel frame mountain bike, the perfect bikepacker, without sacrificing fun on the trail. We have ridden this bike down alpine downhill black runs, bikepacked in the New Forest, and used everyday as a comfortable offroad cruiser. The Big Bro is a classic.

They say...

Our all purpose, tough as nails 29er/27.5+ adventure frame; designed to take you well off the beaten track and beyond. 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 now 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.

We now offer a Rohloff specific dropout set which makes the Big Bro compatible with the Rohloff 135mm Speedhub with OEM axle plate. See here for details.

Like all Brother products the Big Bro has been rigorously tested out in the real world – we took prototypes across the South Downs, through Snowdonia National Park and up to the Scottish Highlands. The Big Bro has since completed two of the worlds toughest bikepacking endurance races – the 4,418km Tour Divide from Canada to Mexico and the 1,710km Silk Road Mountain Race in Kyrgyzstan.
