The 2027 Brother Cycles Big Bro is an adventure frameset for 29in and 27.5-plus builds. It introduces HazelNutter and RadBerry colours with hand-drawn Cloud branding by Matt Blease, while retaining a heat-treated, double-butted 4130 chromoly main triangle and a steel fork corrected for a 100mm suspension setup.

Boost spacing provides clearance for tyres up to 29 x 2.6in or 27.5 x 3in. The replaceable, rail-style sliding dropouts allow geared or singlespeed builds, and the UDH/Full Mount-compatible rear arrangement supports a range of drivetrain choices. A Rohloff-specific dropout set is available separately for a compatible 135mm Speedhub with an OEM axle plate.

Practical fittings include stealth dropper routing, top-tube bag mounts, rack and bottle fittings, and triple mounts on and beneath the downtube. The fork adds triple cage mounts and dedicated front rack fittings. This is a pre-order product rather than confirmed stock for immediate dispatch. The listed price is the full frameset price; availability and delivery timing need confirmation before an order is accepted.
