Does anyone know the proper seatpost clamp size for my 2008 IX NS?

The thumb nut finally stripped (after almost 600 folds/unfolds) and I can't find a suitable replacement; all the other QR thumb nuts I have found tend to bend the bolt at an angle.

I will not be held responsible for giving you the wrong info.
My 2006 N.S. appears to measure 1-1/4 and has a 27.2 post.

Common seat post clamp sizes are 28.6mm (1 1/8"), 30mm, 31.8mm (1 1/4"), and 34.9mm (1 3/8").

So according to this it should be a 31.8 for mine which again measures 1 1/4 inch across.

Anyone want to correct me please speak up.

Also I had my bolt pop on mine, I found another bolt and replaced it. I do not know if it is bending the bolt.

I would not mind getting a wider (meaning top to bottom) and beefier quick release seatpost clamp, does anyone have a suggestion or two?

Thanks.
