Highlights
Why we rate it
XT-level internals
The mechanism and sealed cartridge axle are the same as Shimano's Deore XT M8100 race pedal.
Mud clearance
An offset binding and slim body shed mud and grit, so engagement stays reliable on rough roads.
Stable on rough ground
A wider edge-to-edge platform and lower platform height keep the foot steady on bumpy surfaces.
Walkable SPD system
It uses 2-bolt SPD cleats that sit recessed in gravel and MTB shoes, so you can walk at cafe stops and on hike-a-bike sections.
Limited edition
United in Gravel graphics set it apart. Stock is finite, so availability may not last.

Sachet Instructions

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!
