2014 Orbea Orca OMP 55cm

The Orbea Orca is a pure bred racing frame chosen by the professionals of Team Cofidis!

STIFFNESS

The large majority of torsional and lateral loads are handled by the lower half of any frame. The headtube, downtube and chainstays must resist twisting and transmit the power generated by your legs to the rear wheel. There is no doubt about it, this resistance to flex translates directly to more watts on the road. The new Orca displays massive tube cross-sections in the critical bottom bracket junction, made possible by a wide PF86 bottom bracket shell. The larger diameters increase efficiency and rigidity without adding weight since the material thickness can be reduced while maintaining the same strength. A new carbon forming technique eliminates traditional air bladders and allows for better compaction and less material while maintaining strength. The global stiffness test is used by manufacturers to measure frame deflection. The rear dropout is fixed in place and a force applied to the side of the headtube flexes the entire frame. The amount of movement at the headtube for a given force is recorded in millimeters.

RACING GEOMETRY FIT AND PHILOSOPHY

Racing geometry gets the most of every pedal stroke, efficiently converting every watt into speed. The distances between axles drop, allowing for a more responsive bike that take curves with ease and has great traction when you start pedaling and when you accelerate as well, which saves time and power at the same time. Additionally, a low stack and longer reach allow for a more aerodynamic position on the bike, and a more efficient use of energy. Stack and reach are important measurements because they define the spatial relationships of two important contact points between your body and the bike – pedals and handlebars. Stack is the vertical distance from the center of the bottom bracket to the top of the headtube. Reach is the horizontal distance from the center of the bottom bracket to that same point - the top center of the headtube. An understanding of stack and reach can explain why many small bikes don’t fit well. There are instances in the market when the smallest sizes do not offer shorter reach measurements and do not bring the head tube (therefore the handlebars) any closer to the rider than the next bigger size. How does the manufacturer advertise a full size range then, based on top tube lengths? What we’re suggesting is an evolution in bike geometry. It’s a different way to look at how to design and build bike frames that allows the Orca to fit a wider range of men and women and follow a more linear size progression. 

Condition: Used. 

Headtube has some scuff marks on it followed by some blemishes. Rear chainstay has some blemishes on it. Drive side chain stay has scuffs towards the rear drop out. Bottom Bracket area has minor blemishes on it as well.
