The all Canadian, Next SL crankset by Race Face is easily one of the most impressive options for your mountain bike. With completely carbon hollow crankarms, the Next SL is among some of the lightest production cranks in the world.
The Next SL takes advantage of Race Face's own proprietary spider and chainring interface called the "Cinch" system. Essentially the chainring or spider is held on by a lockring that can be removed with a conventional Shimano-type splined BB tool such as the Park #BBT-22. This means that the Cinch system is extremely secure, while easily swapping to different configurations.
This crankset configuration comes complete with cranks, a double or triple direct mount spider, and a set of chainrings. BB not included.
