New Orbea Ordu billed as the ‘ideal weapon for triathletes’

On display at this year’s Eurobike in an underwater tank, Spain’s Orbea has released details of its new Ordu tri bike, with ‘ergonomics and aerodynamics for triathlon’. Orbea has redesigned the Ordu frame to create ‘the most ergonomic and aerodynamic bike on the market’ with the bike billed as the ‘ideal weapon for triathletes’.

Orbea has worked with user groups to improve the existing geometry and make it fit for athletes’ needs. The main changes are:

  • Seat tube angle (now 78º)
  • Reach
  • Stack
  • Monolink technology applied to power for maximum handlebar position range

With the AIZonE (Aerodynamic Investigation Zone) project, consisting of wind tunnel testing performed by Orbea, the company ‘gained valuable knowledge about aerodynamics.’ This knowledge then translated into:

  • Maximum rigidity: the rider’s power is optimally transferred to the rider’s movement forward
  • Perfect drag coefficient: the force caused by the bike passing through air is ‘the slightest possible on the market’

The knowledge gained was used to improve five frame elements:

  1. Fork: 1:4 proportion to reduce the front surface and improve the drag coefficient
  2. Headset: integrated fork and power to reduce the overall drag coefficient
  3. Down tube, seat tube and seatpost: minimum thickness
  4. Seatstays right on the frame
  5. Rear brakes: in bottom bracket area

Orbea notes that Ordu is a unique bicycle developed to meet user needs in three key areas:

  • Ergonomics: new four-size geometry for a wider range of users – XS (650c wheels), S, M and L.
  • Aerodynamics: every frame, fork and headset part has been taken care of to reduce the drag coefficient
  • Design: Ordu is an Orbea Design product, developed in house with the user in mind, from inception to delivery

74º-80º angle
The Ordu frame allows for 74º to 80º angle range. Two different seat posts are used to cover 74º-76º and 78º-80º angles. The claimed benefits are:

  • Wider position range so that riders can find the position that suits them best and make pedalling more efficient
  • Pedalling position close to traditional road bikes at a 74º-76º angle, recommended for mixed or uphill rides
  • Forward position at a 78º-80º angle, ideal for flat terrain where riders can make the most of their pedalling power
