I have a 110mm 3ttt 4GXL brand new and never fitted (I use the 120 one on my track bike) and a used but nice Selle Italia Monolink (black alloy)- cut to 16.5cm from 6cm insertion to rails. This only has standard saddle clamp not monolink , looks like about 20mm setback. Very adjustable for tilt etc.
