Mondince Frame with 57mm tire clearance

The Mondince FM346 is a gravel frameset with 57 mm tyre clearance, a 27.2 mm seatpost, top tube mounts, chainstay and down tube protectors and down tube storage under the bottle cage. It costs about $580 for frame, fork, headset, seatpost, storage bag and axles, with shipping about $180 to the US or 130 EUR to Europe; custom paint is about $80. Mondince can supply integrated handlebars, including a 30 mm riser bar (narrowest 38 cm). The open mould is shared widely: the rear triangle and fork match the SP Cycle G028, and similar frames appear as Meiner GRL15/GRL17 and TanTan models. The first geometry was criticised as Cannondale SuperX-like: - a 69 mm BB drop, seen as too high for gravel; - short reach (376 mm on size 54); - a long seat tube that limits seatpost flex. In late September 2026 Mondince updated the listing to a new geometry matching the FM376, so these criticisms may no longer apply. Readers noted that the product page gained four glowing reviews on a single day, which looks suspicious. No forum owner has reported receiving a frame yet.
