About this project
Ultra-Durable with High-End Billet Hubs
Rodin Wheels are unique. Here’s why:
To stand up to the rigors of mountain biking, these wheels are made from aerospace-grade composites; which makes them tough enough to withstand a beating on even the most technical of trails. They also need to be light, which is where the 3Drsr technology comes in.
This patented manufacturing process creates a wheel that is a hollow one-piece structure complete with an incredibly tough hook bead rim.
What do these features mean to you? The virtual elimination of pinch flats, no more truing of your wheels, and no more costly dents in your aluminum rims. We simply want you to worry about the ride and not about replacing another set of expensive aluminum-rimmed wheels.
The End of Pinch Flats & Dented Rims
Rodin Wheels are made of a super tough composite with a uniquely shaped hook bead rim to absorb massive impacts. The material's ability to dissipate the impact energy over a broader area and over a slightly longer time allows the tube to survive in most all cases and for the Rodin rim to maintain its original shape without any dents in the rim.
Never Needs Truing
Here’s some tech: The 3Drsr process imparts memory on a molecular level into the polymer chains within the composite material. This fact, combined with the hollow symmetric geometry of the one-piece structure, locks memory into the wheel. This means the wheels’ desire is to always return to its original manufactured state, even after virtually unlimited impacts. In other words, they never need truing :)
With your Pledge all of this can be made possible
Multiple designs were considered and we finally decided to 3D Print two prototype versions, a narrow 5-spoke version and a wider 5-spoke version. The Rodin Team all agreed we should launch the Kickstarter with the narrow spoke wheel design. The wider spoke version is ideal for a NuVinci CVT hub or an electric hub motor so maybe the wider spoke wheel can be a stretch goal if your feedback calls for it.
The prototype hubs used in the filming were actual CNC billet machined units made to our design specifications. The production hubs will be of exceptional precision and quality and CNC billet machined from aerospace grade aluminum, anodized and use precision sealed bearings from our proven vendor.
The two wheel prototypes were 3D Printed as full size mountain bike wheels using FDM (Fused Deposition Modeling) process. Not sure anyone has done that before? No question 3D FDM is cool and we did "ride" the wheels some but they can not be considered structural in this application which is why we now need to step up to 3Drsr to produce the Rodin Wheels.
During filming we had to remove one 3D Printed wheel even though Garrett was doing his best to fly smooth. So, if you look close in the video, you will see that we actually ended up using one of the old school three spokes for some of the action video. The reason the 3D Printed wheels are not fully structural is due to their construction as a series of layered ribbons that tend to separate from each other at loads well below the base material strength.
OK here is some more tech: Patented 3Drsr [Rapid Structural Replication] technology achieves the highest production speeds at the lowest cost within the smallest equipment footprint which allows mass production of single-piece hollow structural composite components. Now, that's a mouthful, but it is this 3Drsr technology that makes the Rodin Wheels possible, and amazingly affordable. It's why we say, “It’s what comes after 3D Printing” when you actually need dozens or even hundreds of thousands of fully structural parts quickly. The technology allows us to design the most remarkable wheels with these otherwise impossible features:
- One-Piece Hollow Structure that is formed almost instantaneously (Rapid Replication) under extreme temperature and pressure unlike 3D Printing that lays down ribbons of melted filament that builds up little by little over many hours. It took 32 hours for each of our full scale FDM 3D Printed prototype wheels whereas the Rodin Wheels will be Replicated in under 5 minutes.
- Freedom to design variable and tapering wall thicknesses anywhere needed to best met the requirements based on FEA (finite element analysis).
- Strategically placed internal ribs where beneficial allows us to add the greatest strength and stiffness with the least amount of material.
- Integrated hook bead rim for tire retention.
- Multiple parts integrated into one-piece structural component.
- Smooth free flowing shapes of the wheel’s exterior make cleaning a breeze and have led to the wheels being described as “Functional Sculpture”.
- Green- 3Drsr has no hazardous by-products.
- Sustainable- Easily recyclable materials- end of use life cycle is important to Rodin Team Members.
Here’s the bottom line: when you combine these amazing capabilities with rapid tooling advancements, there are going to be additional dramatic and exciting projects that previously would not have been considered due to cost or complexity because, 3Drsr allows multiple parts to be converted to a single hollow highly structural component that is affordable. As a backer of Rodin Wheels, we will bring you behind the scenes as the project progresses and you will get to experience 3Drsr and how it makes these wheels possible.

Risks and challenges
As with any new project there are risks as we need to rely on others for portions of the project. But we will be working with established companies that members of our team have worked with in the past and have found them to be reliable. Our team has members highly experienced in product development, very creative and have brought other exciting products to market, so any issues that arise we will overcome. Not to mention we are dreaming of our first trip to Mammoth Mountain, CA for trouble free epic riding.Learn about accountability on Kickstarter
