These hollow carbon cranks are certainly stiff, and the arms emit a resonating sound when you change gear, which reminds everyone that you’re running a very expensive pair of cranks!
Their performance can’t be faulted, and the Phil Wood grease-injected bottom bracket is still running smoothly – although the usual wet British summer may end that.
For comparison, Shimano XTR cranks weigh 52g more but cost £69 less than these. It really depends on how much you want carbon fibre.
Carbon fibre cranks generally rely on internal aluminium spines for strength and rigidity, but RaceFace have dispensed with internal reinforcement here.
Instead, the arms are pressure-moulded and the core is then removed to save weight. With the sheer amount of pressure exerted on the material, RaceFace are able to produce a very stiff and strong crank. The pedal inserts are bonded in a way that guarantees they won’t loosen or creak, they say.
The usual ultra high quality RaceFace chainrings are fitted as standard, complete with shifting ramps and pins that ensure decent shifting in all but the foulest of conditions.
|Name||NEXT Carbon Cranks|
|Manufacturer's Description||The NEXT crank represents another milestone for Race Face. Next cranks are one of the lightest, strongest 100% carbon fiber cranks ever made. Race Face has created a crank that goes beyond existing carbon material & process limitations, setting a new benchmark in performance XC components. NEXT combines over seven years of Race Face composite technology with over fifteen years of crank development, producing a carbon crank with an unparalleled strength to weight ratio.|
|Features||• The arms are the result of over two years of intensive engineering & are manufactured in our British Columbia, Canada manufacturing facility. • Race Face uses the same proprietary carbon material as the new Boeing Dreamliner. This aerospace composite material is available only in North America. • The crank arms are completely hollow with all unnecessary material being removed from the centre core. The composite arms have no internal aluminum spine. • By removing the centre core in the post curing process, our engineers mold at high pressure levels resulting in optimal material compaction & an overall lower void structure. • Race Face Team chainrings are 100% CNC machined from super-hard 7075 aluminum to maximize wear resistance & impact strength.|
