Dean is the ultimate speed machine that’ll have you jetting off the starting ramp or flying out of the transition area. Every detail is designed with optimal turbulence reduction in mind. Comfort is also carefully considered so you can get the most out of your body. From its smart F-Surface Plus teardrop tubing and paint texturing to its hi-tech system integration ranging from fully adjustable aero cockpit to seatpost.
One detail that we’re especially proud of is its dropouts. We’ve opted for standard road bike dropouts on both sides of the bike that can be easily swapped out for other dropouts of varying sizes. This allows you to easily switch tire sizes while keeping your rear wheel nicely tucked into the back of the seat tube at all times. A side benefit of having standard road bike dropouts is that you can simply remove the rear wheel when packing it into a bike box or into your car.
Both cockpit and saddle are completely adjustable so you can nail your unique tuck position. We’ve also incorporated internal cable routing to further reduce the Dean’s drag. Cable routing is simple for easy cable changes as well as maintenance.
About the Dean
The Dean is our extremely versatile bike for that everyday adventurer who thrives on challenges against the clock. Inspired by our Dean FAST, incorporating F-Surface Plus technology, the Dean is made of 30/20-ton high-modulus carbon fibre layup. It is designed for max comfort without compromising efficiency or weight.
It’s for someone who is up for a challenge at any time. Wanna go for the win at your local time trial? Or maybe hit a cool ironman in a foreign country? With the Dean, you can go for it…no support crew needed. We spec it with standard parts that you can find almost anywhere you go.
It’s easy to transport, easy to self-maintain. Heck, it’s even easy to support yourself during the long races thanks to its uniquely-designed bento-box. It’s made out of three parts – base, spacer, box. The more spacers you add, the more volume you win…meaning, the more food you can take.
When you’re ready to take that plunge in making your Dean more aerodynamic, you can simply upgrade to the cockpit components spec’d on our Dean FAST. OR if you are looking to turn your Dean into a regular aero road bike, simply swap the handlebars with standard road drop bars.
F-Surface Plus technology was created so you can convert the same watts into higher speeds. This technology is incorporated into our Noah and Dean models. It is the application of a textured surface (similar to grooves in a golf ball) in strategic locations for decreased wind drag. What these grooves do is create a tiny turbulence which causes the main flow of air to better follow the shape of the tube. With a smooth air travel around the frame, you’ll expertly cut through wind. The stronger the wind, the more you will feel this technology working for you.
Here at Ridley, we set extremely high standards for ourselves. And it all starts with our choice of raw materials. We use only the best quality carbon available, sourced from Toray. They are the world’s leading carbon manufacturer, supplying mainly to the aerospace industry. The grades of high-modulus carbon we use vary from our most pliable 24-ton, which gives the frame flex and comfort, to 60-ton which is our stiffest.
When developing our carbon products, we strictly follow the principle of “form follows function”…down to the last detail. When creating a frame, we first analyse the exact function it needs to serve – how it will be used, how it needs to feel in every possible scenario. Next we design the shape of the frame, taking extreme care of the exact curves, lines and varying thickness of each tube. Lastly is the carbon layup. Combining the grades of carbons to get the exact feel of the bike is like piecing together the most intricate 3-D jigsaw puzzle. It usually involves hundreds of pieces of carbon, assembled in a few dozen layers.
Once this puzzle is complete, what you have is a piece of machinery that is perfectly tuned for its task at hand. Every single one of our carbon bikes exemplifies this extreme attention to detail.
