Currently have an Aéreo Aéreo Wedge ( tube, mini tools, cartridges, gloves etc)
Would like to switch to a bag with a single bottle holder during longer rides to add another bottle.
Would prefer not to add to steering bar.
Have Looked at several brands but they seem to require a long segment of the seat post for attachment (I have 5-6 inches available for the straps) and concerned that the rear light, when mounted, looks or is angled 45 degrees down ( I have R-Flare).
Any suggestions from people using them? Thanks
