SRAM RED XPLR E1 1x 13-Speed Wide 42T DUB Crankset

This SRAM RED 1x XPLR Wide crankset carries a 42T X-Sync chainring, a taller single ring for faster gravel and mixed-surface riding. Hollow carbon arms sit on a SRAM DUB spindle for 13-speed drivetrains.

Lengths on this listing are 167.5, 170, 172.5 and 175mm in Natural Carbon. A DUB Wide spacer kit is included; the bottom bracket is not.

Who It's For

• Gravel and mixed-surface riders on SRAM 13-speed 1x who want a 42T ring
• Faster riders who spin out a 40T on pavement sections
• Frames with 135/142mm road disc hubs and a DUB bottom bracket
• Consider a different crank if you want lower gearing (40T) or arms shorter than 167.5mm

What to Look For

• Spindle interface: SRAM DUB; bottom bracket not included.
• Chainline: 47.5mm, 150mm Q-factor, wide layout for tire clearance.
• Length: 167.5, 170, 172.5 or 175mm with the 42T ring.

Key Features

SRAM's hollow carbon fiber arms keep the crank light for long gravel days.

A DUB spindle needs a DUB bottom bracket matched to your frame, sold separately. The DUB Wide spacer kit (2.5/3.0/4.5/5.5mm) is included to set up the wide position.

The 42T X-Sync ring uses SRAM's 8-bolt direct mount and swaps with a single tool; SRAM offers non-aero rings from 38T to 46T if your terrain changes.

SRAM says this crank can be upgraded to a power meter, sold separately. The 47.5mm chainline and 150mm Q-factor maximize tire clearance.

Rider Intent Summary

• Biggest strengths: A taller 42T ring for speed, light carbon arms and room for wide tires.
• Tradeoffs: 42T is harder on steep, loaded climbs, and the bottom bracket is extra.
• What makes it different: It's the faster-geared RED XPLR Wide option, with a 167.5mm length available.

Victory's Take

We like the 42T RED XPLR for riders whose gravel rides include plenty of fast pavement. Victory Bicycle Studio can help you decide between 40T and 42T for your terrain.
