About The SRAM RED XPLR E1 1x 13-Speed Wide 40T DUB Crankset

Fitted with a 40T X-Sync chainring, this SRAM RED 1x XPLR Wide crankset gives gravel riders a slightly easier single-ring gear on hollow carbon arms. It runs on a SRAM DUB spindle for 13-speed drivetrains.

This listing covers 170, 172.5 and 175mm arms in Natural Carbon. The Wide layout (47.5mm chainline, 150mm Q-factor) is set for tire clearance; the bottom bracket is sold separately.

Who It's For

  • Gravel riders on SRAM 13-speed 1x who want a 40T ring for climbing and loaded riding
  • Riders whose fit calls for 170mm or longer cranks
  • Frames with 135/142mm road disc hubs and a DUB bottom bracket
  • Consider a different crank if you want a 42T ring or arms shorter than 170mm

What to Look For

  • Spindle interface: SRAM DUB; bottom bracket not included, DUB Wide spacer kit included.
  • Chainline: 47.5mm with 150mm Q-factor.
  • Length: 170, 172.5 or 175mm, all with the 40T ring.

Key Features

Hollow carbon arms give this gravel crank the same light construction as SRAM's road RED.

The DUB spindle runs in a DUB bottom bracket, sold separately. The included DUB Wide spacer kit positions the crank correctly for the wide layout.

The 40T ring uses SRAM's 8-bolt direct mount and can be swapped with a single tool. SRAM lists non-aero rings from 38T to 46T, so you can change gearing later.

SRAM states the crank can be upgraded to a power meter, sold separately.

Rider Intent Summary

  • Biggest strengths: A climbing-friendly 40T ring, light hollow carbon arms and wide tire clearance.
  • Tradeoffs: Bottom bracket is extra, and lengths start at 170mm on this listing.
  • What makes it different: The 40T ring trades a little top speed for easier climbing compared with 42T.

Victory's Take

We suggest the 40T RED XPLR for riders who carry gear or face long gravel climbs. Victory Bicycle Studio can check your DUB bottom bracket and length before it ships.

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!
