In this post I'm going to talk about the Mondraker Foxy Carbon 29'' 2019, a new model in the Mondraker lineup with 150mm of rear travel and 29'' wheels. The Mondraker Foxy has always been a Trail Bike, always at the shadow of the Dune, but this new version seems a bit roughter, with bigger wheels and better suspension components it's almost ready for the EWS...
As you can see in the excel table and in the last graphs, the new Mondraker Foxy 29'' has a very efficient system, with Anti-squat values over 100% in all the gears. AS values get a bit lower as the system goes deep into the travel (80% AS at 50% of travel...) but I still think this system is going to work really well with 25% sag and a 1x12 Drivetrain. The LR is not too progressive either and that's another reason to keep the bike with a "firm setup". Having a steep AS curve has Pros and Cons and in this example you can see how the Pedal Kickback (19%) is very low when you compare it with other bikes in the same category. Some people preffer a flatter AS curve but I think this kind of setup works better. Brake-squat (77%) on the other hand is a bit high, but that's completely normal in a Virtual Pivot System.
In the Leverage Ratio graph we can see that the system is Progressive-Regressive (2.6-2.3-2.55) and this is going to be the main problem of the bike. This Leverage Ratio is going to work really well with an air shock and I think the Fox DPX2 (205x62.5mm Trunion) is a really good option, but I'm not a big fan of the Fox X2 in the XR version... It's a great shock and it has a ton of tunning options, but the bike is designed around an air shock and the Fox X2 is not going to have enough Bottom Out protection. In Spain we ride mostly on natural trails, and here a Coil shock combined with a Linear suspension makes a lot of sense, that's probably why the Orbea Rallon is designed in a similar way, but if you are riding mostly on Bikeparks or Trail Centers with a lot of berms, jumps and features an air shock is going to work better.
