Brother Cycles Big Bro Rohloff Dropouts
The Brother Big Bro Rohloff Dropouts convert a compatible Boost-spaced Big Bro for a Rohloff Speedhub with a 10mm axle and OEM axle plate. The sliding plates change the rear spacing from 148mm Boost to 135mm for the hub arrangement specified by Brother.
Choose Version 1 for 2024 and earlier compatible Boost Big Bro models, or Version 2 for the rail-style dropouts introduced for 2025 and later models. Neither version fits the older non-Boost, pre-2021 Big Bro framesets.
The set includes mounting bolts and washers and uses an ISO disc-brake mount. Brother notes that other internally geared hubs may be compatible, but their axle and mounting requirements must be checked individually. Select by frame generation before considering the hub setup.
Available options
- Size: Version 1, Version 2
