Question about Thomson setbacks

Does anyone know the distance from the bend to the rails? I want to make sure that I can actually insert this sumbitch far enough into the frame before I buy one.

Without going out to my car where my bike is patiently waiting for tonight’s ride, I think the distance is 3-4".

If your application is one with that stereotypical “fistful” of seatpost showing, it might not work for you.

Update.

It’s about 4.5 inches or so. And it was just enough. Killer.
