A compact bar that's big on comfort.

FSA focused on comfort when designing the K-Wing Compact Handlebar. The flattened Aero-Ergo profile of the tops is a testament to this. Not only does the profile of the top spread your weight over more of your hands to relieve pressure, but they're also angled down ever-so-slightly. The idea is that angling the tops down mimics the natural position that your wrists assume when you grab the tops of the handlebar. So, you're able to adopt a more natural position whether you're climbing, or just giving your back a rest from the hoods. The moderate 125mm drop and 80mm reach put these handlebars in the realm of short/shallow. And the drops are angled by two degrees in order to mimic the natural position of your wrists when you're in them. It's a subtle difference from parallel drops, but one that becomes apparent the longer that your ride goes on.

The hand-to-bar interface isn't the only design feature that FSA obsessed over. There's a textured clear coat at the stem clamp and brake lever mounts. This high-friction coating ensures a slip-free interface, even on rough roads. The internal cable routing yields clean lines, and the cable channels are slightly larger than you'll find on some other bars. This enables trouble-free cable routing, even with electronic cabling. And while the carbon fiber/Kevlar construction ensures a comfortable ride and plenty of longevity, it's the 3k carbon weave on the outer-layer that makes these handlebars so eye-catching.

The FSA K-Wing Compact Handlebar is available in the sizes 40, 42, and 44cm and in the colors Black and White. Please note that this handlebar is only compatible with 31.8mm clamp diameter stems.

    what does measuring center to center mean when measuring bars for road bike?

    I've put it through the wringer

    I'm pretty impressed with the design and function of these bars. Using several FSA bars currently, these are their best. Probably worthy of 5 stars by most standards. They may affect how you travel with a case and use of a bar fly just fits. Comfortable hand positions for sure, the tops are tops!

    These bars do it all

    I've put it through the wringer

    When logging long miles I suffer some wrist and thumb pain, not debilitating but a nuisance that keeps me from enjoying a long ride. Bought the K-wing hoping to alleviate some of the pain. I am very happy with this purchase, I have completed multiple 50+ mile rides without wrist pain. I like the contour of this bar where it meets up with the hoods, allows much more comfortable positioning than previous bars (3T Ergonova). I am also very comfortable climbing and gripping the top portion of the bar. The slight slant of the bar is much more comfortable than a regular flat bar. I have also noticed less vibration and no longer scoff at the price of carbon, it is worth every penny.

    Rodney, is the bar measured center-center at the bar ends or at the hoods? Thanks.

    Who would have thought?

    I've used it several times

    Ok, so I have to say I have been eyeing these bars for a long time. I like my aluminum FSA Compact bars a lot so I really felt this was, ego purchase. You know, they look bitchin'...happen to match my Tarmac, etc.. Now a couple of weeks in and they are just awesome, The flat area behind the hoods is worth the price of admission alone; insanely comfortable. The ovalized tops are not only more comfy and anatomic when climbing, but make an excellent perch for your forearms in the "faux" aero position. Internal cable routing under the tops is super sano, albeit a bit fiddly to get housing in the first time around...plan on donating a kinked cable to the process. What I didn't expect was just how much more solid and planted they feel when sprinting/climbing out of the saddle, kinda altered my paradigm a bit in this respect. Anyway, pricey but well worth the admission if you feel as I do that your three contact points (saddle, bar, shoes) are a place to invest some green in the name of comfort and performance.

    So what's wrong with the occasional "ego purchase"? Bikes and riding are supposed to be FUN, as well as [fill in the blank]!

    Great Bars!

    Comfort is paramount with these bars. Relatively light and stiff enough to jump out of the saddle and sprint, yet smooths out the road chatter. Exactly what I was looking for.


    Does anyone know if these bars flare on the drops? The other FSA K-Force compact ones I was looking at flare out but the pics on these bars make it appear these do not. Thank you.

    I measured my K-Wings and there is about a 1 cm difference when measured across the front of the bars and across the end of the drops. So there is a small flare out.
