About The SRAM SX Eagle A1 12-Speed 1x 32T DUB Crankset
This SRAM SX Eagle crankset pairs a SRAM DUB spindle with 135/142 (non-Boost) mountain hub spacing, giving older-standard frames a way onto Eagle. Aluminum arms carry a 32T steel X-SYNC 2 direct mount ring.
Arm lengths are 165, 170 and 175mm. SRAM rates it for 11- and 12-speed use and all levels of Eagle drivetrain. The DUB bottom bracket is not included.
Who It's For
- Riders with 135/142 mountain bikes and a DUB-compatible bottom bracket
- Entry-level Eagle builds or replacements
- Riders who want a 165mm option
- Consider a different crank if your bike uses Boost hubs or a Power Spline bottom bracket
What to Look For
- Spindle interface: SRAM DUB; bottom bracket sold separately.
- Hub spacing: listed for 135/142 MTB hubs.
- Crank length: 165, 170 or 175mm.

Victory's Take

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!
