Oak's Philosophy
Oak is a company operated by bike racers. We understand that cycling is an expensive hobby and lifestyle, and we wanted to create a frame that didn't compromise when it comes to performance without costing $5,500. We wanted to build a frame that we'd be excited to race in crits and road races, rip on fast group rides, and proudly lean against the café wall after a ride.
Every design decision was made with that philosophy in mind. We invested in the things that matter most to performance and longevity, while making intentional compromises where they made sense. That's why every bolt, axle and mount is made from titanium, and why we spec'd a CeramicSpeed SLT headset. At the same time, we chose to offer one cockpit option and one paint color. By offering our handlebars in the most popular width for modern racing and eliminating the need for multiple expensive molds, along with simplifying our paint options, we were able to keep the Marca at $2,899 for a frameset while delivering premium performance where it counts.
There was one clear goal for the Marca: to develop a high-end, competitive aero road bike that represents what Oak stands for as a brand - sophisticated design, joy, racing and family.
Built By Racers With Support From The U.S.
Oak is focused on building the cycling community, especially here in the United States. We know there are excellent brands from Asia and Europe offering quality race bikes at competitive prices, and we're excited to see more affordable options in the industry.
Our goal is to offer that same value while backing it with local support. Every frame is assembled, quality checked and supported from Boise, Idaho. That means straightforward warranty support, clear communication, faster shipping and no hassle dealing with overseas imports, tariffs or language barriers. We're here to support you and your riding from our home in Boise.
The Anatomy of the Marca
There are many reasons “why” the Marca has the features it does, but these are some of the most important:
- Aero & Lightweight: No, this isn't an all-around bike, it's an out-and-out aero road bike. That said, we still prioritized making it lightweight and comfortable. The Marca features a super wide fork, deep and extremely thin headtube, extremely thin seatpost, dropped seatstays and deep down tube. These decisions were all made to optimize the aerodynamic performance of the frame.
- Geometry: We wanted something aggressive, yet comfortable and aerodynamic, thus the aggressive angles and high stack.
- Tire Clearance: It was important for us to be able to fit wide road tires and chainrings on this frame. We're continuing to test tire clearance on different wheels, but in most cases, the Marca has clearance for 38mm measured tires.
- Performance & Durability: Again, this is a high-end frameset (even though the price doesn't say so), so we wanted to pull out all the stops. All the bolts, axles and mounts are made of titanium. The headset is a CeramicSpeed SLT headset. This ensures durability of the parts (no stripped bolts here!) and helps reduce weight on the overall frame.
- Handlebars: Designing handlebars was tough because with one-piece cockpits. We were looking at dozens of molds which as a small brand, we couldn't afford. This led us to offer a cockpit that we believe matches the trends and what most racers want. Our handlebar will come in one width and 6 stem lengths. In continuing to prioritize aerodynamics we will offer a handlebar that is 370mm center to center on the hoods and 400mm outside to outside on the drops. We will contact every customer in order to send them the right stem length.
- Paint Job: The Marca features a classy black & white paint job. This is one of the areas where we saved money by going the simpler route. This reduced SKUs, cost and weight and we believe we found the perfect design. A half matte, half glossy, gorgeous paint job highlighting the actual design of the frame with edgy but still minimal branding.
- UDH Compatible: 1x aero builds are a big part of the design of this bike, so the Marca being UDH compatible was a non-negotiable.
- UCI Approved: The Marca is knocking on the UCI's minimum weight limit while maximizing aerodynamic performance.
- Tested & Approved: The Marca passed the highest level of stress testing following international standards, performed by our trusted partners in China.
- Made in China: After lengthy research and visiting multiple factories in China, we feel blessed to have found a factory partner perfect for the job. Developing this frameset with a factory and team of engineers that understood the vision and shared our excitement for it was essential and a big part of the reason for the success of the design.
- Assembled in Boise, ID: All frames and bikes follow 2 rounds of quality control (one in China and one in Boise), then are assembled, packaged and shipped from Boise, ID.
