Size: 61X38mm. Sold as set of 4.
FXX wheels only accept 167 or 688 bearings to save weight. They will not fit the standard 608 bearings.
If you use 7mm axles on your plates, choose the 167 bearings
If you use 8mm axles on your plates, choose the 688 bearings
The urethane is injected through a brand new state of the art injection molding machine. This machine is the only fully digital injection molding urethane machine in the US pouring quad wheels. Normally, a wheel manufacturer will need to mix up a lot of urethane and run a very large and expensive test run of wheels. This limits the manufacturers testing ability as it becomes very costly very quickly. With this new machine, we can pour very small runs, even one set of wheels. Another advantage of this machine is that it is fully digital. You would have seen or experienced some wheels on the market ‘chunking’, where the urethane starts to break apart. This occurs in the older style machines where the waste gate that mixes the urethane may stay open for a fraction of a second too long. As Bont's machine is digital, this does not occur and the wheels are a lot more consistent than other wheel on the market.
Mini Bearing Hub
No expense has been spared on the FXX wheels fully aluminum hub. The hubs are extruded and machined from 6061 T6 aluminum. The hub is designed to fit Bont’s 167 or 688 micro bearings which in combination form the lightest full size wheel on the market. This combination gives you a weight saving of more than 20% over a normal wheel and bearing. This is very noticeable weight advantage for your quad setup. The wheel weighs just 85 grams and the bearing weighs 4 grams. As the hub is designed to fit the micro bearings, no adapter is needed.
We set out to design a hub that was larger than usual. We knew that we had the luxury of having the highest rebounding urethane on the market so we could get away with making an oversized hub without sacrificing rebound. We also felt that 608 and 627 bearings are overkill for quad skating and they just add weight. So the combination of a small bearing hole with a larger outer diameter was our starting point. For the spoke design, we wanted something simple, strong, and aesthetically pleasing while keeping the weight to a minimum.
The shape of the urethane affects the feel of the wheel especially the shape of the lip. With this in mind, Bont paid careful attention on creating the lip of the wheel based on feedback from sponsored skaters.
FXX or Formula XX is Bont's top of the line Made in the USA wheel. The formula for this wheel dates back to the good ol’ days of Hyper wheels. Those who were around in the day will notice that the smell of the wheels brings back the memories of the wheels of old. Bont has taken those old Hyper formulas, updated them, and applied them to the best urethane that money can buy.
