Guru Photon HL
Guru launched three new Photon models at NAHBS, led by the top-tier Photon HL. The HL frame weighs only 670 grams (claimed) for a 54cm size, and represents the culmination of a two-year development cycle. It is a redesign of the old Photon from the ground up, with new tube shapes and carbon technology used throughout. Photo: Caley Fretz | VeloNews.com

The new Photon HL moves from round to squared-off tube shapes, increasing stiffness. Built up as shown it comes in at 10.12 pounds. Photo: Caley Fretz | VeloNews.com

In an effort to keep weight down, Guru went with a traditional 1-1/8" head tube. The Photon HL ships with an Enve 1.0 fork. Cable routing is all internal. Photo: Caley Fretz | VeloNews.com

No, these aren't Guru cranks; they are THM Claviculas with a Guru sticker. The wild looking chainrings are made by KCNC. Photo: Caley Fretz | VeloNews.com

The stripes visible on most of the tubes are a result of a layup technique that involves laying reinforcing strips circumfrentially around the tubes. The strips add strength and stiffness without much weight, like "built in ribs," said Guru marketing manager Phil Pinskey. Photo: Caley Fretz | VeloNews.com
