The Photon HL creates an entirely new category for light frames: Hyperlight. Guru’s QCC (Quantum Carbon Concept) was a breakthrough in Carbon Fiber construction technology. This development gave rise to new techniques that allowed our engineers and designers to push the envelope of stiffness and weight; culminating in the creation of the Photon HL. Using the most complex carbon fiber lay-up in Guru’s history, the Photon HL requires a special time consuming one-man manufacturing process to build. The Photon HL is equipped with high-tech features, including the uniquely innovative IAR (Internal Adaptive Routing) that’s dual compatible with both mechanical and electronic gruppos. Sub- 670 grams for a 54cm translates into one of the highest stiffness to weight ratios ever achieved in cycling. The Photon HL is in its own category above anything else currently on the market. We were so intent on creating the lightest possible frame, that our master painters even developed a brand new proprietary sub 5 gram clearcoat dubbed Specter. Whether you’re ascending the Italian Alps or your hometown hill, we’ve done our part, now it’s all on you!

“one of the highest stiffness to weight ratios ever achieved in cycling.”

Engineered from the ground up to be incredibly stiff and light. The Photon R is the epitome of ultimate stiffness to weight. The Photon R delivers an aggressive feel without sacrificing the Photon’s legendary ride quality. This frame was developed to surpass the stiffness numbers of industry leading frames, while reducing weight. We achieved this ambitious objective and exceeded it by creating an unparalleled race frame that weighs under 80 0 grams for a 54cm! Racers dream of a stiff frame that performs. The Photon R more than delivers with 30% increased stiffness in the bottom bracket region over the original Photon. Torsional stiffness jumps 30% for increased handling and precise cornering, while keeping the same figures in comfort and vertical compliance. Pedal harder and go further. Available in custom and our Fast Forward Race stock geometries, each Photon R is built using our proprietary ORE system (Optimum Ride Engineering) and a composite lay-up driven by the rider’s height and weight. An expanded mix of high and standard modulus fibers are used to provide complete control of ride characteristics and uniformity. Whether you’re 4’11” or 6’4” – you experience the same amazing ride!

The Photon SL retains all of the best qualities of the original award winning Photon launched in 2010. As its successor, the SL continues the tradition of the best blend of handling and vertical compliance – all this and sub-750 grams for a 54cm! Thanks to the Fast Forward Flex geometry and custom options, this frame’s incredible ride characteristics are harnessed and made available to all riders. The SDCD (Smart Design Carbon Dropout) present on the Photon series dramatically increases shifting precision. ORE (Optimum Ride Engineering) allows you to ride farther due to a tuned flex in the seat tube and a vertically compliant rear triangle. Power delivery is more efficient due to 10% greater bottom bracket stiffness. 15% stiffer than the original Photon, the Photon SL lets you ride faster as a result of a higher level of pedaling efficiency. Never be pulled again, now you can attack!

“the SL continues the tradition of the best blend of handling and vertical compliance – all this and sub-750 grams for a 54cm.”


The integration of engineering, design, and craf tsmanship as a global platform for the development of high-tech innovative framesets. A symbiotic methodology that pushes for ward the best aspects of design and engineering to deliver the ultimate ride.

This innovative internal routing system provides for easy installation or conversion of mechanical or electric transmission without having to use dedicated par ts. The IAR system positions the cable stops at optimal locations on the frame to ensure crisp shif ting and responsive braking.

The tube junctions are made with a unique layup that staggers the carbon layers to avoid stress risers and evens out tube deformation.

The totally redesigned full carbon dropout is notably lighter, stif fer and stronger than previous generations, enabling crisp and precise shif ting.

Each tubeset made by Guru is produced with an at tention to detail and a level of craf tsmanship guaranteed to deliver the best ride characteristics for each given size.

The asymmetric backbone (Chainstay - Down tube - Seat tube) of the frame is engineered to maximize power transmission to the back wheel.

The incorporation of the tapered 1â…› - 1½ head tube increases the front triangle stif fness to deliver razor sharp handling, super stable high-speed descents, and rock solid braking.

Fast For ward Race is a true race geometry. Lower head tubes and longer top tubes accommodate road racers or seasoned veterans of the road. This geometry was developed to harness the maximum potential of the frame with regard to the rider’s physiology. FFR is geared toward riders who possess good flexibilit y and are ready for a more aggressive race platform.

Fast For ward Flex is an all- around geometry geared towards accommodating most riders. The true benefit of this geometry is its flexibilit y to morph into either Race or Endurance positions. Not nearly as aggressive as Fast For ward Race, the geometry is nominally taller and shor ter, while retaining aspects of a traditional race geometry.

Guru Cycles has expanded its Fast-Forward Geometry Program by introducing two separate geometries; Fast Forward Flex and Fast Forward Race. The development of two complete and distinct platforms allows us to focus on creating synergy between the geometry and the category-specific features of frames across a range of sizes.
