“Aero from Ewheels came with holes already present, so you just have to jimmy the pedal into the correct slot, line up the screw, and then you're good to go.
Actual performance feels like night and day. Significantly more confident with these on when it comes to mounting and general stability when it comes to things like crosswinds.
Catch is that the overall profile of the Aero with the pedals closed becomes wider; these inserts occupy some space that the pedals slot into when folded.”
