2017 Orbea Alma M25 Bike
The Alma OMP is the ultimate XC rig. Built to be as light and fast as possible, the Alma OMP uses an aggressive geometry and lightweight frame to help propel you to the top of the podium. The Alma feels just as fast descending as it does climbing the steepest of grades.
Orbea separates their carbon frames into two different categories: OMR and OMP, or Orbea Monocoque Race and Orbea Monocoque Performance. The OMP is molded using standard bladders, making it a very light frame at 1150g, with a faster build time compared to the more labor intensive OMR.
Utilizing their "Big Wheel Concept" Orbea offers the Alma in two sizes, 27.5” and 29.” The small and medium sized frames will have 27.5” wheels while the medium, large and extra large frames will have the 29er version. The World Cup Geometry in the Alma OMP 29 has a slacker head angle for stability and control when descending and steeper seat angle and lower stack all for more efficient pedaling and better handling. Orbea also shortened the chainstays making the bike ultra responsive without giving up control.
The Alma OMP 29 has a 4 x 4 dynamic structure. The bottom is stiff and resists twisting while the top is more compliant. This design will give the rider good power transfer but also control over bumpier terrain. The idea behind 4 x 4 Dynamic Structure is that your environment takes a toll on the traction and control of the bike. Orbea innovated a simple solution to this problem, they created a fourth bend in the frame. When you combine this with the thinner chain stays you get a smooth feeling when you ride, like you are floating over rough terrain.
