FM336: The Racer’s Choice
The FM336 is designed for riders who prioritize speed, stiffness, and race‑ready handling. Its progressive geometry (71° head angle, 1030mm wheelbase, 425mm chainstays) strikes a balance between stable high‑speed descending and quick accelerations. The 0.8L internal storage is just enough for a race‑day toolkit, and the frame weight under 1200g keeps the bike lively on climbs. If you're planning to race gravel or enjoy spirited group rides, the FM336 is your weapon.
Ideal for: Gravel racers, fast mixed‑terrain riders, those who want a lightweight platform without sacrificing modern features.
FM326: The Expedition Workhorse
The FM326 is built for adventure. Its 1.2L internal storage is the largest in the lineup, capable of swallowing a full tool kit, rain jacket, and snacks. Eight mounting points (including triple‑pack mounts on the fork legs) let you strap on cargo cages, extra water bottles, or anything else you need for multi-day trips. The slightly longer wheelbase (1040mm) and slacker head angle (71.5°) add stability when the bike is loaded. If you plan to live off your bike for a week, the FM326 is the obvious choice.
Ideal for: Bikepackers, self-supported tourers, riders who carry a lot of gear.
FM316: The All‑Day Endurance Option
The FM316 splits the difference between the FM336 and FM326. It shares the same 0.8L storage as the FM336 but adds an aerodynamic profile that makes it faster on pavement sections. The geometry is slightly more relaxed than the FM336 (identical numbers, but with aero shaping), making it comfortable for long days in the saddle without feeling sluggish. Tire clearance of 50mm gives you flexibility for rough routes, and the 1150g weight is the lightest of the three. The FM316 is the ideal "one bike for everything" – from weekday commutes to overnight adventures.
Ideal for: Endurance riders, mixed‑surface commuters, weekend bikepackers who don't need maximum cargo capacity.
How to Decide: A Simple Flowchart
- Do you race or prioritize speed? → FM336
- Do you go on multi-day self-supported trips with lots of gear? → FM326
- Do you want one bike for everything – fast enough, comfortable enough, with some storage? → FM316
Common Questions
Can I upgrade internal storage on lower models?
No – internal storage is built into the frame. If you need more than 0.8L, choose the FM326.
Which frame is easiest to build?
All three use T47 threaded bottom brackets and internal routing guides, so assembly is similar. The FM326 has slightly more cable guides (for dynamo lighting options), but all are DIY‑friendly.
Will the FM336 fit 50mm tires?
Officially cleared for 47mm, but many users report 700x50mm fits fine with proper rim width. If 50mm is a must, go with FM326 or FM316 (both officially support 50mm).
Are all three EN tested?
Yes – every Mondince frame, including these three, is independently tested to 1.3× ISO 4210 standards. Third‑party reports are available on request.
Which Mondince Gravel Frame Should You Choose?
- Choose FM336 if you want the fastest, race-oriented gravel frame for mixed terrain and group rides.
- Choose FM326 if you need more storage, more mounting points and better support for multi-day bikepacking.
- Choose FM316 if you want one versatile gravel frame for endurance rides, commuting and light bikepacking.
