SRAM RED E1 12-Speed 2x DUB Crankset

The SRAM RED E1 2x crankset gives you the widest choice in this lineup: six arm lengths from 160 to 175mm and three ring pairings, 50/37T, 48/35T and 46/33T, all on hollow carbon arms with a SRAM DUB spindle. It is a 12-speed road crank with a 45mm chainline.

Not every ring and length combination is offered, so check the option list. The finish is Natural Carbon, and the DUB bottom bracket is sold separately.

Who It's For

• Road riders on SRAM 12-speed 2x who want to tune gearing and arm length together
• Shorter riders who need 160 or 165mm arms
• Riders on 130mm or 135/142mm road disc frames with a DUB bottom bracket
• Consider a different crank if you run 1x or need a non-DUB spindle

What to Look For

• Spindle interface: SRAM DUB, bottom bracket not included.
• Chainrings: 50/37T, 48/35T or 46/33T. 48/35T is offered here in 160, 165 and 167.5mm.
• Length: 160, 165, 167.5, 170, 172.5 or 175mm.

Key Features

Hollow carbon arms with a new layup are 29g lighter than the previous generation, according to SRAM.

A SRAM DUB spindle runs in a DUB bottom bracket, which is sold separately. Order the one that matches your frame shell.

The one-piece 2x chainring mounts on SRAM's 8-bolt direct mount interface. Bigger 50/37T suits fast riders; 46/33T suits steep climbs or lower power.

SRAM says the crank can be upgraded to a power meter setup with a power meter chainring, sold separately.

Six lengths including 160 and 167.5mm make it easier to match a fit recommendation exactly.

Rider Intent Summary

• Biggest strengths: Six lengths, three ring pairings and light hollow carbon arms in one listing.
• Tradeoffs: Some length/ring combinations aren't offered, and the bottom bracket is an extra purchase.
• What makes it different: The range of lengths, including 160 and 167.5mm, is wider than most road cranks.
