FSA® SL-K Carbon Crankset
Built for Tern
FSA customizes their legendary SL-K crankset with custom rings and a custom spindle length for us. Why? For the best possible front shifting and gear range on our unique frame geometry.
Optimized Chainrings
If you have a bike with small wheels, you have to work a little harder to get good gearing; you can’t just slap a 53/39 crankset on a small-wheeled bike; the gearing will be too low. Our friends at FSA supply us with custom 55/42t rings so you get a wider gear range and fewer overlapping gears.
TrueShift Design
Tern bikes have a unique frame geometry so it takes a bit of work to optimize front shifting. Fortunately for us, our friends at FSA supply us with a custom length spindle that’s the basis for our smooth shifting.
Feather Light
Weighing in at only 619 grams, FSA’s hollow-arm carbon cranks are incredibly light.
Excellent Power Transfer
Oversized carbon crank arms, a massive BB386 aluminum spindle, and outboard MegaEVO bearings all add up to a crankset that stiff enough for many of the world’s top racers.
