About The SRAM X01 Eagle C3 Fat Bike 12-Speed 30T DUB 66.5mm Chainline 175mm Black Crankset
This SRAM X01 Eagle fat bike crankset uses a 66.5mm chainline, the narrower of SRAM's two X01 fat bike chainlines. It is a 175mm, black, carbon crank with a 30T direct-mount X-SYNC 2 chainring and a DUB spindle (28.99mm).
Matching chainline to your fat bike frame is the deciding factor here. The bottom bracket is not included.
Who It's For
- Fat bike riders whose frame calls for a 66.5mm chainline
- Riders running 11- or 12-speed Eagle on a fat bike who want a 30T ring
- Riders who fit a 175mm crank
- Consider a different crank if your frame specifies a 76.5mm chainline; that is a separate X01 fat bike version
What to Look For
- Chainline: 66.5mm. Confirm with your frame maker.
- Spindle interface: SRAM DUB (28.99mm); bottom bracket not included.
- Crank length and ring: 175mm only, 30T direct mount.
Key Features
Carbon arms. SRAM describes the X01 as the strongest crank in the Eagle lineup.
DUB spindle for fat bike shells. Uses a 28.99mm DUB spindle; a DUB bottom bracket for your fat bike shell is sold separately.
30T direct-mount X-SYNC 2 ring. The smaller 30T ring is mounted via SRAM's 3-bolt direct-mount interface, with raw aluminum teeth SRAM says keep a fresh look over time.

Rider Intent Summary
- Biggest strengths: Fat bike chainline, carbon arms, 30T ring included.
- Tradeoffs: One length only; chainline must match your frame; BB extra.

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!
