2x road crankset
SRAM RED AXS E1 Crankset
SRAM's lightest 2x crankset pairs hollow carbon arms with a one-piece X-Range chainring set, available plain or with a dual-sided power meter built into the rings. A 160mm option joins the range for shorter riders and aero-focused fits.
Highlights
Why we rate it
Hollow carbon arms
Reworked carbon layup trims weight over the previous RED crank while keeping the stiffness racers expect.
Power in the rings
On the power meter version the strain gauges sit inside the one-piece chainring, measuring both legs with no separate spider to add weight.
X-Range gearing
Tight 13-tooth front jumps mean a front shift costs you very little cadence, pairing neatly with SRAM's 10-tooth-start cassettes.
Three ring choices
50-37T for fast road riding, 48-35T as an all-rounder and 46-33T for climbing or mixed-surface days.
DUB spindle
Uses SRAM's 28.99mm DUB spindle, so it fits every SRAM Road DUB bottom bracket standard.

Sachet Instructions
1. Grab your empty old bottle of Muc-Off. (You may need a pair of adjustable pliers to remove the trigger from the bottle). Or purchase our Bottle for Life.
2. Fill up to the shoulders of the bottle with 1 litre of lukewarm water for faster formula activation!
3. Carefully cut one corner of the sachet open along the diagonal cut lines.
4. You can carefully pour the sachet straight into the top of the bottle. Or using the box, fold the inside of the lid together using the printed lines as a guide and use this as a funnel to pour the powder into your bottle. (Please see our video for full instructions on this.
5. Screw your spray trigger back onto the top of the bottle. Ensure it’s tight!
6. Shake the bottle vigorously for 30-60 seconds to activate the formula. If you notice any undissolved powder simply keep shakin’ it!
7. Go clean that filthy bike!
