Carbon Integrated Handlebar/Stem

Though Black Inc and sister brand Factor Bikes are relative newcomers to the cycling industry, the people behind them have a long, storied history. That's why Black Inc is able to boast that, unlike most vendors, it is also a manufacturer; it owns its own factory, so it's literally manufacturing the Carbon Integrated Barstem. The material choice, design, carbon layup, and finishing processes are 100% inside jobs, which guarantees that Black Inc is always in complete control of the quality and—more importantly—the reliability of the bar/stem unit. Given that the Barstem's primary job is to give you control during high-stakes finales and driven descents, you'll be happy to know that the manufacturing process is, as Black Inc pointedly notes, "all about control."

The Barstem is, effectively, a combination of Black Inc's handlebar and stem, albeit with the clamping area removed. Eliminating the need to clamp a stem to a bar eliminates one more chance to crush expensive racing bits. It also lets Black Inc continuously wrap material through the joint, increasing structural integrity and stiffness for those grinding efforts when you're out of the saddle in too big a gear and it feels like you're pulling the bike up a punchy climb by dint of handlebar torque alone. The front-end stiffness of Factor Bikes impresses us, and we suspect the Black Inc Barstem is a big reason why.

The combination design also eliminates the transitional ridges from clamp to bar to stem, reducing the possible footholds for air resistance to forward motion. Increased aerodynamics won't be a huge help when you're slugging it out up a wall, but it'll certainly complement today's species of aerodynamic frames after you manage to punch your way to a gap and are faced with the prospect of maintaining it across 30km of no-man's land before the finish line. The bar's dimensions are compact-yet-comfortable, reducing weight while allowing stability in the drops with a 3-degree flare. That slight bump helps reduce wrist contact with the flats while sprinting—a design element no-doubt informed by the preferences of former green jersey Baden Cooke, one of Factor's (and, by extension, Black Inc's) founding partners.

The Barstem looks as clean as it rides, with the aerodynamic benefits translating to sharp aesthetic lines. The routing further supplement both attributes, with recessed cable ports and internal channels for electronic shifting. In order to preserve the full-carbon body, Black Inc forgoes the usual threaded inserts for the steerer clamp and anchors the titanium bolts with aluminum nuts. As with the Factor Bikes it ships with, the Black Inc Barstem includes an out-ahead mount for Garmin-type, 1/4-turn head units.

What do you think about this product?



Does this come with a Wahoo compatible computer mount?


Are the cable exit holes on the underside of the bar large enough for both housed gear and brake cables for a mechanical setup? Or are they entry holes, because I don't seem to see any holes near the shifter mount area.


Is the width of the drops wider than the hoods (e.g., like the Enve bar)?


Hi, is this bar Shimano Di2 EW-RS910 compatible?

Hi Nate, this bar will work with the Di2 Bar End Junction.

Yes. I’m running them with the RS910. Hides the cables well too.

Sleek System Integration

I've used it once or twice and have initial impressions

This bar/stem is lightweight, comfortable, and good looking. The 40x100 weighed in just under 300g on my kitchen scale. Installation and adjustment was easy and even came with some nice carbon-friendly lubricant. The top bars are flat with a nice transition to the hoods down to a standard swoop down the bars. There is a deep channel on the underside to pretty cleanly route any cables underneath the bar tape that would otherwise look messy. The inclusion of an integrated Garmin mount adds to the cool aero look. The bars are noticeably more comfortable than similar alloy setups and appear to absorb a significant amount of

Thanks for the detailed review Ben!

Very Sleek

I've used it once or twice and have initial impressions

I put in a few rides on the Black Inc. Carbon Integragted handlebars while test-riding the Factor o2 disc. I had some initial concern about the inability to find the right angle for the bars, but Black Inc. nailed the shape on these. I noticed less hand fatigue after 50 miles than I get on my own bike. Plus, they look terrific!


Stem angle? Is width c-c or o-o?

It is -6 degree and is measure center to center.
