FSA SL-K Light EVO 386 Crankset $0.00
The cycling industry's canned reaction to introductions of new standards--especially those of the bottom bracket variety, are usually met with a mix of head-scratching and a heavy dose of skepticism. The EVO 386 from FSA was no different, but a closer inspection reveals a carefully engineered answer to alleviate some of the more nitpicky issues found with the BB30 platform. The FSA SL-K Light EVO 386 Crankset connects you to FSA's new 386 BB standard, while delivering prime stiffness and drivetrain power transfer--both hallmarks of the SL-K Light series.
Among the benefits of BB386 is the larger diameter, and its stiffer spindle. At 30mm, it's the same diameter as a BB30 spindle. The big difference between them is that the BB386 spindle is longer to allow its use in a bottom bracket shell width of 86mm. In allowing for greater shell widths, frame manufacturers have more leeway in creating stiffer and more durable drivetrain platforms. With this crank spindle, FSA uses a low speed extrusion to form the 7075 alloy spindle before they machine it to its final shape. It is co-molded into the 5-arm spider on the drive side arm. The composite spider is hollow to save precious extra grams, as are the crankarms. FSA molds a transverse rib into each hollow crankarm. It's an exacting process, but worth it since it increases the torsional rigidity -- you'll appreciate the rock-solid feel when you stomp on the pedals.
The FSA SL-K Light EVO 386 crankset differs from its K-Force Light only in that of aesthetics, and bearing fitment. The K-Force Light is fitted with FSA's silky smooth ceramic bearings, while this SL-K Light comes with standard steel cartridge bearings--certainly no slouch in their own right, however. In terms of weight, roughly 30 grams separate the two cranksets, and the slightly heavier SL-K Light has more subtle FSA branding on the arms. The unidirectional carbon on the SL-K crank gives it a silky appearance, in contrast to the woven outer layer on the K-Force Light unit.
Both cranksets use the same mold shape. So technically, the performance attributes of the hollow carbon fiber crankarms of both the SL-K and K-Force models are most likely identical. If there's a difference in stiffness, it's measurable in the lab, not out on the road. The other major aesthetic difference is in the 5-hole chainrings. The SL-K features Storm Grey anodized 7075 aluminum where the K-Force Light uses black. Other than the color, they are identical. Though more difficult to produce , T-30 Torx internal wrenching alloy fasteners are used for the chainrings bolts to ensure strip-free, proper torquing of the hardware. A tight fit and snug fasteners means less power-robbing flex and decreased chance for strange creaking noises to develop.
Three crank arm lengths are available -- 170, 172.5, and 175mm in a standard 39/53 gearing. The rings are designed for 10-speed drivetrains. Please note that while the bottom bracket is not included, we do have them available for purchase separately; check sizing chart for compatibility.

I have recently upgraded my bb to Chris king hollowtech. I'm wondering if this crankset will fit.currently on fsa gossamer crankset.
Sorry! It will not fit the Chris King BB that you have unless it's a 30 mm BB. The FSA SL-K Light EVO 386 Crankset has a 30mm Spindle/axle.

I would like to fit the following crank
FSA SL-K Light BB386 EVO Road Crankset
Rotor PressFit 30 4130 Road Ceramic Bottom Bracket
To my scott foil 20 2013
Currently it has shimano ultegra shaft length 110 mm x 24mm
Please could you confirm the shaft length on the slk and it will fit
There should be no issue running the 4130mm BB86 converter, but you might be also check out the FSA BB86/386EVO Adapter. Although the Rotor product would work, in my experience it is best to keep components that work in unison such as a crankset/bb from the same manufacturer since the tolerances can vary to a small degree from brand to brand.

I just picked up my 2014 Specialized Allez C2 road bike. Will this crank work with this bike and the 2400 Claris drive train? If I need a different chain etc that's no biggie. I just want to make sure I can mount the crank. Of course I'll need to get the EVO 386 Bottom Bracket too correct?

Will this FSA SL K LIGHT crank work with shamino 7900 chain, 10 speed cassette , front and rear 7900 derailers and 7900 shifters smoothly?
Yes, this crankset will work with a Shimano 7900 drivetrain - and it will work quite well - though I would strongly recommend a 7900 chain along with the rest of the group.
Stiff, with excellent power transfer!

Great crank! I have over 1000 miles on this crank. I upgraded to this guy from some cheap SRAM one that came stock with my bike. I love the thick, carbon crank arms. There's no flex whatsoever, even when I'm sprinting the bike at ~30mph. Additionally, as with all carbon parts, it dampens the ride making it much smoother. Also, it looks pretty sweet! Definitely an eye-catcher on the road. Only downside I can think of is weight. I have a full SRAM Red set up except for the crank. I went with this guy because I found this one for a lower price (that was the deal breaker for me), although I think the Red crank is lighter weight (still wayyyy lighter than the aluminum crank I used to have). Overall: I can't recommend this crank enough! No flex with great power transfer! Well worth the money!
