Brother Stroma 105 build

Availability: In stock (1)
Delivery time: Collection Only - From our Peckham Store

The Stroma is Brother's new Reynolds 725 steel all-season road frame – a versatile, year round road bike suited to the ever changing weather and road surfaces of the UK. The bike is fast, responsive and most importantly fun to ride and we’ve designed it to accommodate large volume road tyres meaning you won’t need a different bike for every season.

The Stroma truly lives up to its namesake; a remote island off the rough north east coast of Scotland, battered by ferocious weather and near impenetrable tides.

The Stroma is constructed out of Reynolds 725 steel; a heat treated tubing famed for its strength and weight saving properties and an ideal material for the challenges posed by year round road cycling. We’ve matched this with the Brother full carbon road fork up front giving you a lightweight and responsive front end with optimum power transfer. The frame and fork have fitted eyelets for full mudguards and clearance for up to 35mm tyres or 30mm with mudguards. Other features include thru-axle flat-mount dropouts, replaceable dropout inserts, 2 x bottle cage and rear rack mounts, and Di2 routing.
