Product Description

Ever wonder what?s been happening with aluminum since carbon fiber has become all the rage? In some cases, it?s only gotten better by being swept along in the mad rush for lighter ? stronger ? stiffer. With the Alma 29 Hydro, Orbea shows that metal can still compete with carbon. On a strictly performance basis, the Alma 29 Hydro is a fantastic machine. On the scale it?s still the underdog in comparison to its carbon fiber big brother, but it wins big time at the checkout.As the name would imply, the Alma 29 Hydro makes liberal use of advanced hydroforming technology to shape the tubes. The tube profiles and general shaping mimics the carbon fiber version, and there?s a reason for it all. You?ll see that both the front and rear triangles are actually quadrangles, with four corners and four sides. The fourth member unlocks the triangle in a way that invites a small amount of deflection in the frame. Orbea?s engineers intended it to absorb some of the harsh input from the trail. They call it their 4x4 design. Couple this comfort-adding design with the advantages of 29er wheels and the Alma Hydro 29 is a true all-terrain bike.Like we said earlier, aluminum has been improved over the years. Where we used to ride with straight gauge alloy tubes many years ago, Orbea employs TIG-welded, triple-butted tubing here. The butting process reduces the wall thickness away from the weld zones where the tube can be thinner and therefore lighter. This helps with ride quality as well. The thinner tubes temper the overall stiffness of the frame. One of our favorite elements from the Alma 29 Silver is the lack of bridges on the rear stays. This seriously increases the tire clearance so that mud and leaves that get stuck to your rear tire can pass through without getting hung up. The Alma Hydro gets this same free-running design. The aluminum Alma also uses DCR (direct cable routing). This version can use a standard cable set as well as Gore?s slick-shifting cables like the carbon versio
