Mount your OneUp EDC pump (or any a 30-28mm diameter pump) to a standard bottle cage mount or “auxiliary mount” found on Transition, Norco, Forbidden, Revel, Trek, and more. The inline mount hides the pump from the line of sight while riding and keeps it away from your ankles and knees as you get super steezy. Please check that your pump will fit with your specific frame size/bottle cage by test fitting your pump in the space it will be mounted. If it doesn’t fit without the mount... it's still not going to fit with it.
Get's ride of that silly side mount an makes the best use of the extra under top tube space. Very happy.
