Running 2 different ITM , trekking bars ,

got a 3rd quite adjustable and the semi rectangular C tube can take
widgets between the 2 clamps, joining it and the U shaped 1" upright that goes in the stem .. I could sell #3

I have a pair of stems stacked , on the steerer, raised the stem.. and gained space underneath..

the lower one carries the bar bag mount, 1" Tube.
it could be a longer tube as a widget collection mounting place.. .

SJS has a welded T to go on as if a 2nd stem , but only needs 1 bolt around the steer.
one style can slope downward to set the bag low, closer to the top of the wheel.
