Race Face Next XC Cranks Review

Pro Reviews

Impressions
The set came with a very trick set of ‘Pedal End Boots’, which go over the end of the crank arms to protect them. I am always bashing my pedals and crank arms into rocks, so I really like these, not only for the protection they offered the crank arms, but the subtle cushion, they provided to me on impact with rocks. I am willing to put up with the small weight increase (16g) for these on any bike.

The CNC 7075 aluminum chainrings (22/32/44) shifted quite nicely using their patented S.H.I.F.T. technology, and when I did miss a shift once, the hollow arms made a unique ping noise. Do they shift as well as XTR? Close, but no, they are not yet at that magic XTR shifting level. The cranks did not come with the newer turbine shifting, so I can’t comment on its shifting abilities.

While out riding I really noticed how stiff these cranks are, they give me instant power access and there was no noticeable slop in the system from them. I like to do a lot of slow speed and hard torque moves on technical terrain, which really puts a lot of stress into the drivetrain system, and these cranks were incredible in that realm. I found myself moving down one gear on some of my rides due to the increased ability to apply power to the ground. They offered fast acceleration and provided a snappier feel while cranking and mashing on the pedals. I could make some ugly technical climbs that I haven’t been able to do before or at least could now do with better style.

He takes those same strengths and a good dose of insanity to his reviewing and writing on mountain biking products, creating technical, in-depth and hyperbolic articles. Whenever he's not on the bike, he might be found watching MotoGP racing, otherwise look for him out on extremely technical singletrack.

    Nice review! I still have the old Turbines and also run the Dues X-type with 180mm cranks arms on my SS. One thing I can tell you is the RF stands behind their products and they have been happy to replace/warrenty parts as needed. I will buy these cranks if I build a new XC or trail bike but don’t think I would ever need to replace my old RF cranks because they are built to last.

    Hi,
    Are you forced to use RF’s bottom bracket or could i keep my CK BB?

  • pastajet says:

    No you can use any of the industry standard X-Type external bottom bracket…
