CX lever and Ortlieb Ultimate 4 (plus?) bag
I have both CX levers and an Ortlieb Ultimate 4 (plus?) handlebar bag.
I think it's important to:
1) Buy levers that don't stick out too far (some stick out more/less than others)
2) Get a handlebar bag that has a fairly long mounting post
As most people who've been responding that they have both seem to have an Ortlieb handlebar bag, I think you can assume that at least that bag (and who knows which others...) tends to give enough clearance...
As long as I tilt the levers down somewhat (but still in a comfortable position) then my fingers don't get squeezed against the levers when using them.
