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. 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. The frame is priced around $605 USD with a 30-day lead time, but it has been temporarily delisted from the website; the company plans to release it when stock is available in two months. Some concerns remain about fake reviews and overall brand reliability.
