Mondince Frame with 57mm tire clearance

The Mondince FM346 is a gravel frame with 57mm tire clearance, inspired by the Cannondale SuperX geometry. It features a 27.2mm seatpost, top tube mounts, and comes with a chainstay and downtube protector. The frame is available with custom paint and decals. Pricing is around $580 for frame, fork, headset, seatpost, storage bag, and axles, plus $180 shipping to the US. The geometry has been a point of debate, particularly the 69mm BB drop and long seat tube, which some find unsuitable for gravel riding. The frame is also being released by Tantan.
