About The SRAM SX Eagle A1 12-Speed 1x 32T Powerspline Crankset

The SRAM SX Eagle crankset puts Eagle styling and a 32T steel X-SYNC 2 ring on aluminum arms at the entry level of the Eagle range. This version uses a Truvativ Power Spline spindle and is listed for 135/142 (non-Boost) mountain hubs.

It comes in 170 and 175mm arms. SRAM lists it as 11/12-speed compatible and compatible with all levels of Eagle drivetrain. The bottom bracket is sold separately.

Who It's For

  • Riders on non-Boost 135/142 mountain bikes running SRAM Eagle
  • Frames set up for a Power Spline bottom bracket
  • Budget-minded repairs or upgrades to 11/12-speed
  • Consider a different crank if your bike has Boost hubs or a DUB bottom bracket

What to Look For

  • Spindle interface: Truvativ Power Spline; Power Spline bottom bracket sold separately.
  • Hub spacing: listed for 135/142 MTB hubs, not Boost.
  • Crank length: 170 or 175mm.

Key Features

Steel X-SYNC 2 ring. The 32T direct mount steel ring is included, and SRAM states it offers the same chain retention as higher-level Eagle cranks.

Aluminum arms. Aluminum keeps the SX at the entry point of Eagle while staying sturdy for trail use.

Power Spline spindle. The Truvativ Power Spline interface needs a matching bottom bracket, which is not included.

11/12-speed compatible. SRAM lists the crank as compatible with 11- and 12-speed drivetrains and all levels of Eagle.

Rider Intent Summary

  • Biggest strengths: Entry-level Eagle compatibility with a durable steel ring.
  • Tradeoffs: Bottom bracket sold separately; non-Boost spacing only; two lengths.
  • What makes it different: A Power Spline, non-Boost version for older-standard 135/142 frames.

Victory's Take

At Victory Bicycle Studio we use this version mostly to keep non-Boost bikes running on Eagle. We confirm hub spacing and the Power Spline bottom bracket before ordering.

Frequently Asked Questions

Do you offer free shipping?

We do offer free shipping on non-bike orders over $100. We do not offer free shipping for bicycles unless it is a one time promotion. Generally, bike shipping will cost $150 and that covers just the shipping of the bike with no assembly. If you were to bring that bike to your local mechanic or bike store, you would pay them their assembly fee. If you choose our Professional Assembly option for $200, our service technicians would assemble the bike before shipping and then re-pack the bike safely for transit. When you receive the bike you would attach the front wheel, attach the seatpost/saddle, and raise the handlebars and clamp them. Those three items do have to be detached to minimize or eliminate the chance of damage in transit.

How much does shipping cost?

For orders of parts, accessories, apparel, etc. on orders under $100, shipping is a flat rate of $9.99. Regular bike shipping without assembly is $150, bike shipping with Professional Assembly is an additional $200 (so $350 in total which includes the $150 of regular shipping). Our White Glove Delivery option is $699 and that will cover the assembly of the bike and our White Glove Delivery partner delivering your dream bike to your front door, ready to ride!
