The 2018 Brother Cycles Big Bro has been designed with versatility in mind, as after all, no two adventures are the same. So 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 cro-mo tubing and comes with 100mm suspension corrected forks. There’s now clearance for big 3 inch tyres on 27.5+ wheels or up to 2.4 inch tyres if you’d prefer a 29er. It features 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. Both the fork and frame also allow the use of a fender and pannier rack. S-bend chainstays with replaceable alloy sliding dropouts allow for geared or singlespeed setups.
Like all Brother products the Big Bro was rigorously tested. We took prototypes across the South Downs, through Snowdonia National Park and up to the Scottish Highlands. Most impressively a first-generation Big Bro also completed the 2016 Tour Divide – a 2,700 mile mountain bike race from Canada to New Mexico.

This is the disc brake version of our all-purpose, all-road steel adventure frame. Designed to take on whatever challenge is thrown at it – whether that’s thrashing along gravel trails, a weekend bike-packing trip or even a full blown transcontinental tour.
Kepler can run up to 42c tyres when you need that extra grip, however it’s equally happy running slicks when you want to keep up with the roadies. And of course it’s fully equipped to fit front and rear panniers if you’re loading up for a longer trip. It features laser cut disc dropouts, s-shaped chainstays and a unicrown steel fork. The double butted chromoly tubing makes for a tough yet lightweight ride which will keep going for years to come.
