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

This SRAM SX Eagle crankset combines a Truvativ Power Spline spindle with 141/148 Boost hub spacing, for Boost bikes that run a Power Spline bottom bracket. It uses aluminum arms and a 32T steel X-SYNC 2 direct mount ring.

Available in 170 and 175mm. The bottom bracket is sold separately. SRAM lists 11/12-speed compatibility and compatibility with every level of Eagle drivetrain.

Who It's For

  • Boost (141/148) mountain bikes with a Power Spline bottom bracket
  • Riders keeping an existing Power Spline setup while moving to Eagle
  • Entry-level 12-speed repairs
  • Consider a different crank if your frame uses DUB or non-Boost spacing

What to Look For

  • Spindle interface: Truvativ Power Spline; matching bottom bracket sold separately.
  • Hub spacing: 141/148 Boost.
  • Crank length: 170 or 175mm.

Key Features

Power Spline spindle. The Truvativ Power Spline interface lets this crank drop into frames already set up for that bottom bracket. The bottom bracket is not included.

32T steel X-SYNC 2 ring. Included and direct mount; SRAM states its chain retention matches higher-level Eagle cranks.

Boost spacing. Listed for 141/148 Boost hubs.

Aluminum arms. Entry-level aluminum arms with Eagle styling.

Rider Intent Summary

  • Biggest strengths: Eagle on Boost frames without changing from Power Spline.
  • Tradeoffs: Bottom bracket sold separately; two lengths only.
  • What makes it different: Pairs a Power Spline spindle with Boost spacing.

Victory's Take

At Victory Bicycle Studio we suggest this version when a Boost bike already has a good Power Spline bottom bracket. We will confirm spindle and spacing 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!

How can I track my order?

When you place your online order, you will receive an instantaneous email update with your order number and order details, and shortly after, you will receive a follow up order email with the tracking number for your order.  If you still need assistance with your order, feel free to email us at online@victorybicyclestudio.com and we will respond asap.
