HMX - NET carbon

HMX - NET carbon: Scott is one of those brands that manufactures as many catchy names as it does products. (Something to do with companies starting with ‘S’?) HMX refers to a special high-modulus carbon with a custom resin system that Scott uses to reinforce key areas of the LT 10’s front section. The NET part (Naked External Tube) reminds us that Scott was among the first carbon fiber bike makers to abandon the cute looking woven cosmetic outer layer and to leave the frame’s unidirectional carbon construction exposed – a strategy that saves weight and remains honest to the material. HMX material is said to be 20-percent stiffer, and thus adds rigidity and can reduce weight in the areas where it is employed.

One-piece molded front section: There are many strategies used to make carbon parts, the best method to make a strong hollow shape, like a front triangle, is to lay up the many layers of carbon material and the various bearing and shock mounts into one complete piece and then use internal pressure, evenly distributed, to compress the carbon within the mold as the part is heated to set the resin. A one-time cure produces the strongest bond between the carbon layers. This is the method used to produce the best of the best carbon frames, including the Genius LT 10.

The LT 10’s composite front section is intelligently designed to optimize the material’s unique properties, which explains why it doesn’t look like a slightly sculpted rendition of a generic welded-aluminum-tube frame. Its tri-oval top and down tubes bear a hint of convention, but its tapered head tube area, its massively oversized seat tube and the rear-set bottom bracket are voluminous monocoque constructions integrated into the design to double as suspension pick up points and to encircle its three-chambered pull-shock.

All-mountain frame features: Scott took advantage of Shimano’s PressFit bottom bracket system to boost strength and stiffness by widening the bottom bracket/seat tube as far as possible. An ISCG chain guide mount is built into the left side of the monocoque and Scott attaches a red-anodized inner guide plate to keep the chain in control and to protect the carbon from injury should the chain be forced off the inside sprocket. In the rear, the post-mount brake caliper boss is tucked inside the frame to keep the caliper out of harm’s way. A Scott and Trek exclusive for 2012 is an internal hose routing for its RockShox Reverb seat post remote-control. Scott also attaches its direct-mount front derailleur to the swingarm instead of the seat tube so the derailleur cage tracks the chain perfectly as the rear suspension compresses through its full travel. Finally, the Genius LT 10’s seat tube mast is angled back to lengthen the cockpit as the post is raised in order to accommodate taller riders and to move the rider forward in a more downhill position when the saddle is slammed low.
