Thanks !!!
Im working on the right (drivetrain) side. The right direction - clockwise. I'm ussing the correct tools (this is not the first BB I'm replacing) ... The wrench has been broken - the result is a sore on my finger...
I want to replace the BB because the crankset looks bend (untrue when rotating). After replacing with other (good) crankset the result remains the same, so I decided to replace the BB.
I will buy another wrench and try again tomorrow. Probably a long 8mm screw will keep the tool on place.
I cannot return the bike because I cannot prove that it is not damaged by myself...
Thanks again !
