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.
What About 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.
