Reviews & Ratings
The Mondince FM126 is a 2026 aero road bike frame made by Long Teng, featuring a claimed T1100/T800/T700 carbon layup, monocoque EPS construction, and T47 threaded bottom bracket. It supports up to 32C tires (with potential for 35C), has UDH compatibility, and is available in sizes 49-61. The Indiegogo campaign failed to reach its goal, but the frame is now available for direct order at ~$850-950 with handlebars, or ~$765 without. Weight is around 900-1050g painted with hardware depending on version. The frame has been praised for its value, OEM background (Cube, Argon18), and geometry similar to the Tarmac SL8, but criticized for inconsistent communication, non-monocoque construction (two-piece bonded), and handling concerns on larger sizes due to steep head angle and 47mm fork offset. Early batches experienced a fork crown race issue causing a visible gap between head tube and fork; Mondince has acknowledged this and is sending a revised crown race. The seatpost has a stated minimum insertion of 120mm, but the manufacturer indicates 100mm is acceptable; a 400mm seatpost is available. A notable concern reported by a user is significant lateral flex at the bottom bracket, especially during sprints over 1000W, making the frame feel less stiff compared to other frames like the LightCarbon LCR018; Mondince states it passes ISO standards. Some users also reported an incorrect Di2 battery mount, but the seatpost can hold the battery without it. Overall, the frame offers excellent value but has some fit and finish concerns and potential stiffness issues for powerful riders.
AI Summary
Pros
- Excellent value for the spec: high-modulus carbon, monocoque EPS, T47, UDH, and aero design at a fraction of Western brand prices.
- Produced by Long Teng, a reputable OEM for brands like Cube, Argon18, and Ribble, adding trust in quality.
- Geometry closely mirrors the Specialized Tarmac SL8, a proven race platform, with good stack/reach for most riders.

Cons
- Indiegogo campaign cancelled due to low backer count, leading to delays and price increases; communication about changes was inconsistent.
- Frame is not true one-piece monocoque; it is made from two bonded molds, which may affect weight and perceived quality.
- Handling concerns on sizes 56+: steep 74° head angle combined with 47mm fork offset results in very low trail (~49mm), potentially twitchy and unstable.
