Rival 1 BB30 Crankset

Now that 1x drivetrains are the defacto choice for mountain and cyclocross riders, SRAM sets it aims at providing road and gravel cyclist the same simplicity and weight savings with its Rival 1 group. The Rival 1 BB30 Crankset is the centerpiece of the group and turns your pedaling into the forward movement with precise aluminum construction and outstanding chain retention.

With SRAM's commitment to 1x, it's been producing wide range cassettes and rear derailleurs that allow for the gearing possible with only one ring. When the crossover, repetitive gear choices are removed from a 2x setup, the gearing options become very similar to 1x. We've seen pro's riding with single chainrings for TT and Tri's and with the likes of Team Aqua Blue fully committed to running 1x for the entire road season, we think the changing tides are sure to hit the shores amongst serious cyclist on the tarmac.

SRAM constructs its crank arms from forged aluminum allowing for efficient power transfer at a price point that's way friendlier than its carbon fiber offerings. The narrow/wide teeth are the hallmark design allowing 1x drivetrains to exist without some form of additional chain retention device. It features alternating, regular teeth with squared-off profile teeth that capture the chain's inner plates improving chain stability and retention. For gravel and 'cross cyclists, SRAM wisely includes recesses that help clear mud when it's messy out.

  • SRAM 1x performance and a great price
  • Aluminum construction keeps weight low and values high
  • The narrow/wide ring provides excellent chain retention
  • Crank designed for frames with BB30/PF30 frames

Solid Crankset at a great value

I've used it several times

When I first got into riding gravel the added maintenance and occasional dropped chain with a double chainring and front derailleur soon convinced me that 1x must be the way to go so I bought a used carbon crank, slapped on a Wolf Tooth drop stop chain ring on it and never looked back. After a few seasons the used crank gave out. Not anxious to pay for a brand new carbon crank, I was pleasantly surprised to find that the aluminum Rival 1x crank weighs only 200 grams more than the carbon Force and costs $85 less...that's tire money folks! The crankset was easy to install and adjust taking all of 15 minutes. I've used it for about 6 weeks now and it performs very well with no appreciable flex for the relatively skinny dude I am . The anodized aluminum finish seems more scratch and scuff resistant than carbon is. Overall I'm very happy with the purchase . My experience with the Rival crank and other products in the group shows me that Sram Rival is a solid choice at a great price point.
