Mondince FM366 aero gravel bike with 57mm of tire clearance

The Mondince FM366 Gravel is a new aero gravel frame with 57mm tire clearance, featuring a flip chip for adjustable rake (50/55mm) and an aero D-shaped seatpost. It combines aero qualities of the FM316 with the tire clearance of the FM346. Initially, the geometry chart showed extremely short reach numbers that were widely criticized and later confirmed to be incorrect. A revised geometry chart has been released with more reasonable reach, similar to the FM336, and max chainring clearance of 52T (though one post mentions 46T). The frame is priced around $605 USD for frame, fork, seatpost, axles, headset, bag, with custom paint at $100 per color; EU price is €750 including shipping and tax. Lead time has fluctuated: initially 30 days, then 50 days, then delisted; as of July 2026, it was listed as a pre-order with frames ready in ~20 days, and later a preorder had an 18-day lead time. The frame is now listed on the website again. Some concerns remain about geometry inconsistencies (old vs new) causing confusion, lack of a dedicated integrated handlebar, and the aero seatpost limiting dropper post options. The downtube storage cover is anodized aluminum. The geometry is surprisingly slack for an aero frame. User reviews are pending, with some waiting to see final builds before ordering.
