{"product_id":"brother-cycles-stroma-2025-frameset","title":"Brother Cycles Stroma 2025 Frameset","description":"\u003cp\u003eThe 2025 Brother Cycles Stroma is a Reynolds 725 steel all-road frameset for regular riding through changing weather and road conditions. It suits an endurance road bike, a practical commuter or a light touring setup, with a full-carbon fork and fittings that support a useful year-round build.\u003c\/p\u003e\u003cp\u003eThe frame accepts tyres up to 38mm, reducing to 32mm when full mudguards are fitted. The 2025 carbon fork includes internal dynamo routing, while rear rack mounts, two bottle positions and Di2 cable ports add flexibility. Those frame ports can also be used for a rear dynamo-light cable.\u003c\/p\u003e\u003cp\u003eElectric Blue and Rubble are the colour options for this model-year listing. The sale price applies to the frameset rather than a complete bicycle. Use the geometry and component specifications below to choose the right size and plan a compatible wheelset, brake system and finishing kit.\u003c\/p\u003e\u003ch2\u003eTechnical specifications\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eFrame tubing: Reynolds 725 heat treated chromoly double-butted main triangle, ED coated.
