* The bike in the pics is an example we built up of the 2025 model
The Stroma is our versatile, year-round road bike, designed for the ever-changing weather and road surfaces of the UK and beyond. All-road, fast gravel, endurance – however you want to classify it, the Stroma is fast, responsive and comfortable over distance, no matter how rough the road gets.
The Stroma lives up to its namesake; a remote island off the north east coast of Scotland, battered by ferocious weather and near-impenetrable tides.
The frame is built from Reynolds 725 steel – a heat-treated tubing that offers an excellent balance of strength, weight and ride quality, and one we think is particularly well suited to a bike designed to be ridden year-round. Up front, our full-carbon road fork keeps things light and responsive, with internal dynamo routing, further enhancing the Stroma’s endurance credentials.
There’s clearance for up to 38mm tyres, or 32mm with full mudguards, with fitted eyelets on both the frame and fork.
Other details include thru-axle flat-mount dropouts, replaceable dropout i
