The Seymour frameset is the foundation of Evercoast's dedicated road bicycle a heat-treated, triple-butted 4130 chromoly steel frame and matching steel fork built specifically for pavement riding and finished with rim brake mounts by design. Not a gravel frame pressed into road service. A road frame built with a clear point of view about what a road bicycle should be.
The Seymour is built around rim brakes: lighter, simpler, and more progressive under braking than a disc road setup at this price point. The dual pivot rim brake caliper standard is the most widely serviced brake standard in the world. Any shop, anywhere, has the pads and the knowledge. Combined with a BSA English threaded bottom bracket, 27.2mm seatpost, and 31.8mm cockpit, the Seymour frameset is built to be owned and maintained for decades without specialist tools or proprietary parts.
The steel fork runs a QR 100mm front axle with standard dual pivot rim brake crown mount. Tire clearance accommodates up to 700x28C: enough for a comfortable road tire with room for light mixed-surface use. The heat-treated, triple-butted 4130 chromoly construction absorbs road vibration progressively, which over a three or four hour road ride is felt in your hands, your lower back, and your energy levels at the end of the day.
Bring your components or let us spec the build for you. The Seymour pairs naturally with a complete Shimano 105 R7000 mechanical groupset, which we stock, for a complete road build that is honest about what it is and genuinely excellent at it.
