This triathlon and time trial bike is inspired by Ridley’s fleet of world-class race bikes. The high-modulus carbon fibre frame is what you want to pull off the rack when you need to put some distance between you and the pack. The priority is aerodynamics: droplet-shaped downtube, oversized tapered headtube, internal cable routing, rear-facing font brake, but the Dean RS Ultegra throws a realistic nod to comfort: shortened top tube and a lengthened headtube. When you encounter turbulence en route, the F-split fork pulls air away from the wheel and spokes, reducing drag by about 7.4%. The Regular Seatpost (RS) makes travel easier for those flying to Kona, or wherever your race destination may be. Ultegra 11-speed drivetrain makes power transfer extremely efficient and the lightweight Fulcrum Racing Quattros makes manoeuvring feel effortless. Here’s to you slicing through the wind.
- Built from the ground up, the Ridley Dean RS HM frame is made of a resilient blend of different strength (40 to 24-ton) high-modulus unidirectional carbon fibre for the right blend of stiffness, lightness and resilience.
- F-surface technology strategically places textured surfaces in areas where air slips off the frame, to smooth overall airflow and reduce drag by approximately 3.6%.
- Droplet shaped, aero-optimizing tubes allow the airstream to closely follow the profile of the bike. F-split fork helps pull air away from the wheels (and spokes) reducing turbulence and drag.
- Adjustable aero carbon seatpost is ideal for travelling triathletes, packing up easier than an integrated seat mast.
- Oversized tapered headtube increases the contact area of the lower headset bearing to add rigidity and dissipate vibrations.
- Shimano Ultegra 11 speed drivetrain delivers smooth, efficient power transfer from rider to road.
- Pressfit 30 bottom bracket allows the use of wider down tube and bottom bracket shell, providing maximum power output.
- RotoR 3DF Semi-Compact cranks are designed to be extremely stiff and lightweight; a necessary combination for both sprinting and climbing.
- Deda Kronos TT carbon handlebars adds a tight, controllable cockpit and customizable stem-bar combination.
- Racing Quattro wheelset is entirely hand-assembled by a specialized Fulcrum technician, double checked via electronic instrumentation.
- Internal cable routing is clean, aero, and compatible with mechanical and electronic shifting. Mechanical cable stopper can be removed for conversion to electronic shifting.
- This model is not equipped with pedals.
- Bikes are covered by MEC's Rocksolid Guarantee and Bike Service Agreement. You can bring your bike to any MEC Bike Shop for free adjustments and minor maintenance for a year after purchase.
- Ridley was born in Flanders, Belgium, a region infamous for harsh cycling conditions. Against this backdrop Ridley engineers, tests, and refines their frame construction, race technology, tube profiles, and their own branded component line, 4ZA.
Geometry influences comfort, efficiency, and how the bike handles, particularly its steering.
