FSA Superlight Carbon Crankset

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.
