2016 Fuji SL Super-light Climber's Bike - 19 Percent Lighter Than Ever Before
The Fuji SL was born out of the quest to create one of the lightest bikes in the world by building off our grand tour-winning design and introducing technology that shattered expectations of what’s possible. When meticulously evaluating where one tenth of a gram can be shaved, smart things happen.
Claimed Frame Weight: 695g |
Not only is the SL significantly lighter, it’s significantly stiffer: 9% stiffer in the head tube, 11% stiffer in the bottom bracket, and 18% stiffer in the fork (than our Altamira) for maximum efficiency and superior handling.
How Did They Make It So Light?
The SL’s frame is manufactured using a process introduced with the Altamira in 2013 called “High Compaction” moulding, which combines internal and external moulds to produce a product that’s as finished on the inside as it is on the outside. This avoids the unnecessary addition of weight, and distributes resin more evenly during manufacturing, producing the strongest possible frame.
While the Altamira features eight bonded joints, the SL uses only four; the more bonding joints you eliminate, the stronger and lighter the frame becomes – as redundant material is removed and you’re utilizing carbon’s strongest properties of continuity. The SL’s seatstays and chainstays are molded into just two, hollowed pieces, including the dropouts – shaving grams and increasing strength. These reductions play a big role in why the SL is a remarkable 237 grams lighter than the Altamira – nearly double the weight savings most brands boast of their next generation road bike.
What About Stiffness?
A lightweight frame alone won’t get you up the mountain. The frame needs to be stiff to ensure every pedal stroke and every ounce of energy is efficiently translated into propelling the bike forward. The SL’s downtube is uniquely octagonal in shape, featuring flattened sections of ultra high-tensile strength carbon that is compromised if not used in flat orientations; the seat tube, top tube, and fork also feature flattened sections of high-tensile strength carbon, which maximize lateral stiffness.
The fork has a reinforcing rib – a patented technology from Fuji’s carbon manufacturer called Reinforced I-Beam or RIB technology – that runs the length of the fork blades, amplifying stiffness for razor-sharp steering precision.
The frame uses a PF30 bottom bracket, which further improves power transfer by allowing for the use of larger diameter, lighter, and stiffer alloy axles.
