An all purpose, tough as nails, 29er adventure bike – built to take you well off the beaten track and beyond. Whether you’re running a lightweight bikepacking setup, front and rear panniers for a ’round-the-world’ tour or stripped back to thrash some forest trails the Big Bro can handle it.
The frame is made out of tough 4130 double butted cr-mo tubing with a 100mm suspension corrected fork, both with corrosion resistant ED coating applied. It comes equipped with the latest Sram NX Eagle 1×12 groupset – providing reliable shifting in the toughest of conditions. WTB Ranger 2.25″ tyres on WTB ST i25 29″ rims are a trail ready “bikepacker approved” wheelset that excels on longer rides. Last but not least the SRAM Level T hydro disc brakes give you confidence-boosting stopping power all day long.
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.
