Update 6th October 2020: We have 1 large black left in stock, and then that’s it until the restock!
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, stripped back to thrash some forest trails or even front and rear panniers for a ’round-the-world’ tour 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. There’s clearance for big 29 x 2.4″ tyres or up to 3 inch tyres if you’d prefer to go 27.5+. 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.
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.
