About The SRAM S500 Eagle B1 12-Speed 1x 32T DUB Boost Crankset

The SRAM S500 Eagle DUB crankset brings carbon crank arms and a 32T aluminum X-SYNC 2 ring to standard Boost mountain bikes. It uses the regular DUB spindle with a 52mm chainline for 141/148 Boost hubs.

Arm lengths are 170 and 175mm, and the DUB bottom bracket is sold separately. It is a lighter step up from aluminum-arm Eagle cranks while staying on the same 3-bolt direct mount ring standard.

Who It's For

  • Trail riders on 12-speed Eagle with 141/148 Boost hubs
  • Riders who want carbon arms without moving to a higher tier
  • Riders whose fit lands on 170 or 175mm
  • Consider a different crank if your frame uses a 55mm chainline or a Powerspline bottom bracket

What to Look For

  • Spindle interface: SRAM DUB (standard width); bottom bracket not included.
  • Chainline and spacing: 52mm for 141/148 Boost.
  • Crank length: 170 or 175mm.

Key Features

Carbon crank arms. The carbon arms keep weight down, which is the S500's reason to exist over aluminum-arm options.

32T aluminum X-SYNC 2. An aluminum ring on SRAM's 3-bolt direct mount interface keeps the chain controlled and the package light.

DUB spindle. SRAM says DUB brings uniform bottom bracket fitment, better sealing against contamination, and forward and backward compatibility. The bottom bracket is sold separately.

Boost chainline. The 52mm chainline lines up with 141/148 Boost hubs.

Rider Intent Summary

  • Biggest strengths: Carbon arms on a standard Boost DUB crank.
  • Tradeoffs: Two lengths only; bottom bracket sold separately.
  • What makes it different: Carbon arms with an aluminum ring on the regular 52mm DUB platform.

Victory's Take

At Victory Bicycle Studio we suggest the S500 to riders upgrading from an aluminum Eagle crank who want a lighter feel on a Boost bike. We check 52mm versus 55mm chainline with every order.

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.
