Next SL cranks should be SixC for the Shore. Next cranks intended usage should only be for XC or Trail, of course not DH , but even All Mtn. or Enduro is gonna be too much for these super light cranks. Unfortunately I learned the hard way (twice). The stress from All Mtn or Enduro is too much for the Next SL.
SixC are on the way for moi.
By no means am I unhappy with Race Face Quality, but I do feel that the Next SL have been mis-marketed in the way that all of us believe they will handle the wear and tear of N.Shore riding….they won't , go with the SixC or the Alu Turbine to be safe.
+1 on the Next SLs. I've been through 2 sets as well, 1 a year. First one the pedal insert came loose(that arm replaced), and second new pair I didn't see but my shop told me something about the insides or inserts cracking (both arms replaced). SixCs are the proper 'Enduro' cranks. I'm 190 lbs, about 150,000m of vert a season so I really shouldn't complain.
