Mondince FM316 2026 AERO Design Gravel Bike Frame

The Mondice 2026 AERO Design Bike Frame FM316 is an open-mold carbon gravel frame with aero design, internal storage, and T47 bottom bracket. It is sold by Mondince and other suppliers like SPCycle (model G026) and TanTan. Key attributes include a price around $485-662 for the frame/fork/seatpost/headset, weight of approximately 1240-1343g for frame and 410-473g for fork (size M/L), carbon construction, and compatibility with 50mm tires (with about 5mm clearance). The geometry is progressive and similar to the Mondraker Arid, with long reach and steep seat tube angles. Two fork options exist: a 395mm axle-to-crown (FM316) for aggressive geometry and a 420mm (FM326/FM326) for more relaxed handling. The frame includes features like a mechanical storage compartment, flip-chip fork options, and UDH hanger. However, the geometry charts were initially inaccurate and revised multiple times, causing confusion among buyers. Recent feedback highlights the FM316's very fast and responsive handling, described as 'stupidly fast' like a cross bike, with riders noting excellent maneuverability. The flip-chip allows adjustment of the front axle position to fine-tune steering. Delivery to Europe typically takes about 1 month via air freight, though delays can occur. The FM316 is considered the most aggressive Mondince frame, with geometry close to a road bike, making it suitable for fast gravel or all-road builds, while the FM336 is a different design more akin to the Trek Checkpoint.
