a friend of mine got a new sponsor and didn't need his Litespeed anymore. so he gave it to me. unfortunately the integrated aero seatpost was about 15mm too long. I tried to find a way to chop it down without the proper cutting guide tool, but that would have ended in a catastrophe. I ordered the Park Tool cutting guide SG-7.2, which has been delivered today and I finished this project.
the tools: just check the fotos ...
