2017 Orbea Alma OMR
XC racing is incredibly demanding and requires the lightest and stiffest bike in order to be as fast as possible. Orbea has revamped the Alma to meet the demands of XC racing, creating one of the lightest mountain frames ever.
Orbea separates their carbon frames into two different categories: OMR and OMP, or Orbea Monocoque Race and Orbea Monocoque Performance. The OMR frame uses EPS molds instead of bladders and uses minimal overlap. The overlap is significantly less than on the Orbea OMP models, giving the OMR a weight savings over the OMP.
They also use higher modulus fibers where needed. Less wrapping is used because continuous carbon fibers run through the bends. The result is a stronger, stiffer, lighter frame. In fact the frame only weighs 950g but is 25% stiffer and 10% more compliant!
Utilizing their "Big Wheel Concept" Orbea offers the Alma OMR in two sizes, 27.5” and 29.” The small and medium sized frames will have 27.5” wheels while the large and extra large frames will have the 29” version. The World Cup Geometry in the Alma OMR 29 is a slacker head angle for stability and control when descending. A steeper seat angle and lower stack all for more efficient pedaling and better handling. Also they shortened the chainstay making the bike ultra responsive without giving up control.
The Alma OMR 29 has a 4 x 4 dynamic structure. The bottom is stiff and resists twisting while the top is more compliant. So there is good power transfer but also good control over bumps in the road. It makes the bike both more efficient and smooth. And this is all compounded by where the team at Orbea designed the bends. There is a bend right before the seat tube and the seat stays are flat and thin. This creates a natural flex point. According to Orbea, it makes it feel like you are “Floating over rough terrain.”
