Master links are also integrated into the plastic body where the multi-tool and tyre lever are attached to. The hollow cylinder at the bottom is the perfect place to stash small things like a patch kit, cable ties or money. The cylinder can also be replaced with a 12 g or 16 g CO2 cartridge. All of these tools are integrated in such a way that they do not make noise when slid into the steerer tube.
For those who don’t want to install the EDC Tool into their steerer tube, there is the mini-pump version, in either 100 cc or 70 cc volumes. The 100 cc version can fit the complete EDC Tool plus a CO2 cartridge and the 70 cc only fits one or the other.
