The R is for Rally.

We love the rugged and durable DH and enduro worthy SixC cranks on our big bikes for no-question performance and the ultra-lightweight and stiff Next SL crank on our XC whips. Sometimes it leaves us wondering, what cranks to put on our trail bike and if we have to make a compromise. Wonder no more. The Next R Crank Arms are designed for epic days out on the mountain where climbing is ever present and weight is important, yet hardy enough to ensure it can handle drops and jumps so you aren't stranded on the mountain. Handmade in Canada and constructed from unidirectional carbon fiber, the arms feature the downhill rated SixC G2 pedal inserts preventing blown out threads and stripping. A 7075 alloy spindle keeps the package trim and transmits every watt through the drivetrain. Cinch technology enables tons of ring option and compatibility. Available in in 170 and 175mm options.

  • Lightweight carbon crank built for enduro abuse
  • Cinch platform offers tons of versatility
  • No compromise crank for climb heavy days and durability
  • 170 and 175mm options

What spindle is this? I have a 2015 Santa Cruz Bronson with a 73mm threaded bottom bracket. Will this crank work for that bike? Thanks.

Hi Dale, the spindle is 134mm so these will fit your bike. You'll need a Race Face Cinch threaded bottom bracket.

I have a yeti sb5.5 with gx eagle. What bottom bracket do I need for these cranks?

Hi Bryan, the SB5.5 has a BB92 bottom bracket so you'll need a Race Face Cinch BB92.

Hey Bryan,

This crank would be great for that bike. Here is the bottom bracket that you would need.

Will these fit on a Yeti sb4.5 with boost wheels?

Hi Don, these will fit an SB4.5, you'll need a Race Face Cinch BB92 bottom bracket.

what all is included with this? Just the arms or is the spindle included as well? Would I just need to buy a chainring?

Hey Tanner, this will include the crank arms and spindle. Feel free to contact a Gearhead to assist in making recommendations to complete your build.

Great Stuff

  • Familiarity: I've put it through the wringer

Love these things. Crazy light and surprisingly durable. I've beaten these things up and they still look like they've only been on a couple rides. Well worth the price. Very effective.

So does this come with both crank arms and 30mm spindle?

What is the Race Face part number for the 175mm crank arms? I need to make sure I'm ordering the correct part. Thanks!
