I borrowed that tool in my LBS , one winter, so slow season , and took 0.1mm of tube wall out and so made my RB-1,

a 27.0 , take a more common 27.2 seat post..

and the seat tube bore was also much smoother than the rushed job the factory did , to meet production quotas.

Stronglight post is fairly thick walled.

I spent about 20 minutes sanding down the post. I wrapped sandpaper around it and in a twisting motion went at it. Little by little it did go from 26.21 down to 25.98 or so. Arms got tired aftet a while so ill take another stab at it later today
