Race Face SIXC Handlebar Review

Components Pro Reviews

Reviewed by Brian Mullin http://www.gramslightbikes.com/

The Race Face SIXC 3/4 Riser handlebars are pretty sweet carbon bars, that are light, strong, and have an optimal width and decent rise. I tested the SIXC cranks recently, and these bars have the same toughness, subdued graphics and colors, and they certainly mean business.

The All Mountain SIXC bars are made with the Race Face proprietary Optimized Carbon Technology, and the all carbon bars are light, tough and strong. The 730mm or 28.75 inch (measured) wide bars have nicely marked indicator lines every 12mm at the ends, to help you evenly cut the length, if one is so inclined. If you decide to cut the bars, you’ll need a special carbon saw, a face mask (suggest 3M 6000 half-face respirator with P100 filters) and eye protection.


They come with some standard carbon bar specs of 9 degrees rearward bend, and 4 degrees upward sweep, which makes for a 3/4 inch or 20mm rise, and a 31.8mm clamping diameter. I would have preferred a tad more rise, and at least 1 inch would have been nice, though I know 1.5 inches has some design issues with carbon bars. The bars are reinforced under the grip and shift area, for additional strength and durability, and it especially helps with lock-ons. The mellow graphics and matte carbon color scheme make them blend in well, in a sort of stealth mode look. This is not some wimpy carbon bar, they are beasts who can take some amazing amount of abuse and crashes (tested that one), but are still light at 221.7 grams (measured) and stiff, with a decent touch of tactile resiliency. Supposedly, they test a bar from each run, and abuse it to make sure they are keeping tight tolerances within their engineered design specification’s.


So far, they have been pretty stout, and the surface has seemed to be immune to deep scratches, try as I might, and has only shown minor scuffs and scrapes. I really like the width, as it’s somewhere between the typically shorter All Mountain bars, and the uber wide Freeride and Downhill bars, and it still allows me to sneak through tight tree runs without bashing into them. The SixC handlebars have a US MSRP price of $129, which is in line with most of the competitions carbon based bar selection.


Bottom Line
The Race Face SIXC 3/4 Riser handlebars are light, strong, durable and abuse proof. Their pricing and geometry are right in line with the competition, though I wish they were in a 1 inch rise instead of 3/4? Race Face has used their carbon technological expertise, and morphed it to the All Mountain category with the SIXC series, and the bars and their brethren cranks are massively stout beasts who can take amazing amounts of torture, without a whimper.

The SIXC bars are a superb product, that has excellent strength, and weight, and a few small hidden features tossed in order to complete the package.


  • Light
  • Strong
  • Optimal width


  • 1 inch rise would be nice
  • Extra bonus – 12 degree rearward sweep!

    The bar needs to be rotated up a little in the stem. That will also give you the little more rise that you are looking for.

    These are great bars. Comfy bend and perfect rise. The 3/4 rise is perfect for the modern aggressive trail rider. Low and flow. Been on them for about 6 months. Been through many trail rides, XC and SD races. The only complaint I’d have now is width. These bars are old news now, at 28.5″. 29.5″ is the new 28.5. Just switched over to the Easton Havoc carbons. My guess is Race Face is working on a new wider carbon bar.

    I noticed the rotation issue with your set up too. Swing them up a bit, you’ll be more stoked, and will likely change the 4.5 to a 5.

    I agree – I have a pair and love them. A decent stiffness and some vibration damping, but good width to add control.

    As the others have said, you do need to rotate them forward a bit in the stem, judging by your pics !

  • Stephen says:

    Lol…..yes,that is the first thing you notice….that concerns me and sends up red flags when a product tester does not know proper bike set up then does a review on that said product….FAIL!!!!
