Is there a flexible tube that distresses the valve stem when attached for pumping (as other Topeak pumps use)? Or does this pump attach directly to the value (as a classical frame pump would), with no distressing mechanism?

Asked by: YeOldeBuzzard
The Ninja Seatpost Pump does not have a flexible tube. The pump attaches directly to the valve on your tube.

Is mounting this pump (inside the seat tube) compatible with a DI2 system which has also used the option to mount its battery inside the seat tube?

Asked by: YeOldeBuzzard
The Ninja Seatpost Pump is not compatible with the Shimano Di2 Battery.
