Summary

Photon Hl
CARBON ROAD FRAME
the lightest custom frameset in the world, weighing sub-650 grams for a 54cm frame.
The Photon HL is the lightest custom frameset in the world, weighing sub-650 grams for a 54cm frame.

Using our proprietary QCC technology, Guru engineers have pushed the envelope again, and achieved an even lighter and stiffer frame. The stiffness to weight ratio increases by 5%, which is the result of reducing the weight of the frame while maintaining stiffness. Manufacturing a frame in the sub-700 gram category is a true feat of engineering excellence. Decreasing frame weight at this level by even 5 grams is a tall order and a challenging task. This year's Photon HL boasts a reduction of 20 grams.

Among the list of engineering and design improvements, the Photon HL features a tapered headtube. The benefits of a tapered fork can be felt in every aspect of the ride. Combining the Photon HL with a tapered fork increases power transfer, facilitating cornering and control upon descents.

Building our frames in-house to the customers' exact dimensions gives us the ability to mold tubes using an innovative hollow mandrel molding technique. This allows us to remove a significant amount of structural glue and create parts with increased synergy. Riding this frame will change the expectations that every cyclist demands from a bike.

Photon Series

The ultimate balance between technology, innovation, and craftsmanship; these frames represent the tireless work of an elite team of engineers and industrial designers working to create remarkable products that redefine their respective categories.

The secret to the unparalleled ride offered by these frames is Guru’s Quantum Carbon Concept: A unique understanding of the properties inherent to carbon fiber. Using this constant, the tube shapes were engineered to maximize tangential surfaces around the joints and the lay-up was optimized to minimize superfluous material. This quantum approach makes for a superior riding frame that is incredibly light.

In-house production by expert craftsmen allows for incredible flexibility and speed in the iterative process of research and development.

Ride tuned by people who love to ride. The Photon HL (Hyperlight), the Photon R (Race), and the Photon SL (Superlight)
