A balance of comfort and performance. Made to ride.
This 1st generation custom road frame is a true aero bike made for real world riding. We've studied data-driven simulation results, CFD and generative, as well as fabric layup optimization to create the most efficient frame on the road. The RF20 is the accumulation of 20 years of fiercely passionate design and technological research.
Lead Time: 8-12 weeks

Our super slim, hourglass shaped, head tube reduces drag more than 30% over the front of the frame. Using 1 ⅛ to 1 ½ steerer tubes, the RF20 head tube, increases braking performance and front-end stiffness.
The RF20 uses a proprietary aluminum shell BB that adheres to the standard BB386 bearing and spacing system. We've manufactured a custom aluminum housing that creates a symmetrical concentricity throughout the BB, allowing for parallel accuracy and less chatter.
Integrated "pre-load" spacers placed between each bearing help eliminate crank pre-load forces. Even more, we've designed custom "contact free" bearing seals that are meticulously measured in relation to crank and bearing faces. These seals provide extra protection from dirt and grime as well as eliminate wind drag within the BB system.
The RF20 incorporates the standard 142 x 12 thru-axle system.
As strong as carbon fiber is, it still can be a victim to repeat abrasion. The headache of removing a wheel that has contact with the frame can create weakened fibers. We've purposefully designed the RF20 dropout so that the hub and skewer always make contact with a metal part. The hub locater point is a CNC'd metal part, allowing for consistent and reliable wheel removal and replacement.
Personally, we dislike the ugliness of exposed skewers, so we've created a custom, hollowed, ultra-light (32 grams) thru-axle that lines up flush with both frame dropouts.
The RF20 utilizes a 140mm direct mount disc brake found standard in current high-end industry bicycles. Our chainstay system is designed and simulated purposefully to accommodate for the loads applied for disc brake calipers and rotors.
Designed to compliment the RF20 all-around design, the seat post boasts a slim, aero-foiled shape. Simulated for both wind and maximum weave orientation, our seat post replicates the thoughtful construction used throughout the frame to enhance the comfort and stiffness our riders expect.
Our frames are all hand-laid with pre-impregnated uni-directional, short and long strand, and biaxial braided sleeves. Standard and Hi-Modulus carbon fibers are offered for custom layup options. We work hand-in-hand with our clients to identify where they want to apply structural integrity and weight savings.
Our RF20 is intended to align with the riding styles from everyday cyclists to pro-athletes. We offer a broad range of frame sizes to fit a majority of our riders. We also encourage those with special geometry requests to work with our team to customize your frame for a proper fit.
