Race Face SIXC Crankset Review

Components Pro Reviews

sixc_bike

Bottom Line
The Race Face SIXC carbon cranks are pretty darn sweet, they are light, stiff and offer good shifting. I liked the integrated bashguard, the choice of double or triple chainrings, and the Pedal End Boots. The SIXC cranks are nicely engineered and manufactured, and the overbuild and chainring combination’s really fit in with the All Mountain paradigm. This is an amazing lightweight crankset, that is all carbon (outside of the CrMo spindle and pedal inserts), has incredible power transition to the wheels, looks great and has very cool bash guards for the crank arm ends. They are one of the stiffest, and snappiest cranks I have ever used. Crackalicious!

Happiness is a nice Stiff one.

Strengths
- Stiff
- Lightweight
- Arm end caps
- Carbon

Weaknesses
- Pricey
- Not quite XTR shifting

Overall Rating: 4 Flamin’ Chili Peppers

    Wow, same weight and similar design to XT for double the price.

    >> Wow, same weight and similar design to XT for double the price. <<

    And less durable too, what a deal!

  • Brian Mullin says:

    Disco:
    Weight: No, not the same weight, 100g less
    Design similarity: SIXC are carbon, both are hollow, slightly different designs
    Price: like I stated, pricey

    Dave:
    Durable: Not sure how you have judged their durability? How long have you used them?

  • Disco says:

    Did not see the weight of the BB was included, so 90 grams for triple the price. “Progress” like this is why some dudes still run Square taper, still at least they are from this continent but still heavier and more expensive than Cannondale’s BB30 crank. Hopefully race face figured out durable bearings.

    Race Face has a history of reliability issues with its carbon cranksets…a recent example:
    http://www.bikefix.net/2010/06/bikefix-initial-review-raceface-next_28.html

    I have no doubt that this model will continue the Race Face tradition.

    Shimano XT is as reliable a crank as you will ever find.

  • Race Face says:

    Our Deus crank is the same weight and strength as XT. The SIXC crank is 100 grams lighter and 35% stronger in testing than our Deus crank (and hence XT). No one can currently match the strength to weight ratio of this crank. Deus and XT are XC/Trail cranks. The SIXC is AM to light freeride (6 inch bikes/6 foot drops).

  • Brian Mullin says:

    Dave:
    I have used the Next cranks for almost 1.5 years, and never had the spider crack issue, and the bottom bracket has lasted as long (or longer) than my Shimano versions. I had a Shimano M-960 XTR that had pinch bolt and crank arm fixing bolt issues (broke the latter twice). The SIXC are ultra beefy in the spider section, they are not some weight weenie crank (though they are light), they are a AM crank.

  • Vanguy says:

    XT is a nice crank, but durablility is in question. I pulled the pedal threads out of 2 sets before going to Deus. The Deus have been problem free for a year now (I was told Deus uses a stronger aluminum for their arms). Every company can have quality issues from time to time. XT is hardly the end all be all. I found them weak….
    A fried of mine also has the Next cranks and thay have been trouble free for well over a year (and he’s got them on his AM bike). Very strong and lighter than XTR..Dismissing a brand because of one or two bad reviews is crazy…There are plenty of bad Shimano reviews out there as well…

  • Simon says:

    BTW, the Double, 24-36-Bash that I have is 720g without the BB, BB is 111g MORE. So the weight is SAME as XTR.

  • riley says:

    the more accurate comparison would be crank and bb weight without chainrings. as you can see, they weighed with double and bash, and a bash ring weighs a lot more than a 42/44 tooth chainring, so its not comparable with a triple set up. and at the end of the day, its an all mountain crank compared to an xc race crank. yes it is expensive, but when you are already spending $3-4000 on a bike it really isnt that much more
