Orbea Orca Aero M20 Team Disc Road Bike 2020
Orbea's Orca Aero M20 Team Disc Road Bike gives you the perfect blend of speed and comfort through an aerodynamically designed frameset and complementary components. It's the Spanish brand's first aero designed bike and takes advantage of the relaxed UCI rules through its 3:1 ratio Freeflow fork, reducing the airflow pressure and, consequently, drag. The flatter sides of the frame tubes reduce friction and soften the airflow, while the use of an oval-shaped aero seatpost further reduces turbulence. The frame may well be designed for rapid speeds but it doesn't lose the fun and lively handling of a lightweight performance road bike. The carbon construction is rigid, particularly at the head tube, bottom bracket and chainstay junctions, for efficient power transfer, and each frame has uniquely optimised tubing so every rider can reap the same benefits.
Shimano's mechanical Ultegra disc groupset is responsible for shifting, which is smooth and precise, and braking, which is effective in all weather conditions. The Fulcrum Racing 400 wheels are fitted with wide 28mm Hutchinson Fusion 5 All Season tyres, for comfort and rapid rolling.
- OMR carbon fibre construction
- Freeflow fork - The wider fork opening reduces airflow pressure via the wheel and the fork achieving a 4-watt drag reduction. The new UCI legal fork designed according to the latest regulations, providing all competitors with a 3:1 advantage ratio
- Double radius - Opens up airflow around the tubing profile, with improved airflow over the different angles
- Flattened sides - Reduces friction at the front of the tubing and provides better drag at low speeds
- Orca aero seatpost - The seatpost is adjustable with a broad range of saddle adjustment positions
- The head tube, bottom bracket and chainstay junctions are optimised for improved torsional strength. The sections have been optimised for each size frame to create a more rigid structure
- The headset and stem spacer design allow for several bar/stem options * ICR (internal cable routing) Plus - friction-free, easy to install and low maintenance setup. Compatible with, mechanical and all electronic and wireless transmissions
- Multiple bottle cage mounts provide several configuration options, to improve aerodynamics or improve the distribution of the bike’s centre of gravity
- Shimano Ultegra R8000 11-speed drivetrain and hydraulic disc brakes
- Fulcrum Racing 400 clincher wheels and Hutchinson Fusion 5 All Season 28c tyres
