OneUp EDC puts tools in your steerer tube

More details on this tube-based multi-tool

OneUp Components is best known for its wide-range upgrade cogs. Its latest project is a significant departure from drivetrain upgrades, but no less useful. 


The EDC system, short for everyday carry, is a smart take on tool integration. The Canadian manufacturer is making good use of the empty space in your mountain bike’s tapered steerer tube to house a multi-tool.

We first caught a glimpse of this new tool system at Sea Otter and this article has been updated with additional information now that EDC tool is available.

Down the tube

We’ll work our way down from the top of this new tool storage system.

Since there’s a tool-filled cylinder taking up the real estate that would otherwise be occupied by a star-nut, a different method of pre-loading the headset is required.

All things are cyclical in the cycling industry, and for OneUp at least, we’re back to using threaded steerer tubes — sorta. The EDC tool relies on a threaded headset top cap with a cassette lockring interface to preload the headset.

This will require riders, or their local bike shop, to cut several rows of threads into the fork, ideally in several millimeters of steerer above the stem.

As you might have guessed, this is only intended for alloy steerers. OneUp sells the steerer tube tap alongside the new tool for an additional $35. (UK and Australian pricing TBC.)

OneUp has a video on its site that demonstrates how the tapping system works.

The tool itself is housed in a plastic cylinder. 

Here’s the run-down of all the tools that make up the EDC multi-tool. 

  • 2, 2.5, 3, 4, 5, 6, 8mm Allen keys
  • T25 torx
  • Tire lever
  • Chain breaker
  • Quick link breaker 
  • Spare quick link storage
  • Flat head screwdriver 
  • 0,1,2,3 spoke keys
  • Presta valve core tool
  • EDC top cap preload tool
  • Spare chainring bolt
  • Sealed storage capsule or 12,16, 20g CO2 cartridge storage

Rest assured that you wouldn’t have to lug around a cassette lockring tool to make trailside adjustments. A pair of prongs protruding from one of the multi-tool’s arms will allow riders to pre-load the top cap.

Prongs on this arm of the multi-tool will allow riders to tighten their headsets (as well as their cassettes, if needed) on the trail

A second hollow cylinder screws onto the one that houses the multi-tool. This provides additional storage possibilities for zip-ties, a patch kit or other small items. Alternatively, this portion of the EDC tool can be swapped for a CO2 cartridge.

Not keen on cutting threads into your steerer? That’s fine. The EDC system will also fit inside OneUp’s new high-volume hand pumps

The final portion of the tool is a plastic plug inserted into the base of the tapered steerer tube to prevent the tool or any of its accessories from sliding out the bottom of the steerer, which would obviously pose a safety hazard.

The OneUp EDC system is available for purchase now and will ship on or after 5 July.


Since this is a third-party tool designed around existing forks, there are some caveats when it comes to installation. Visit OneUp’s compatibility page to see if your fork will work with the EDC system.
