Hi, it is me again with my "BB knocking".. Thank you for your previous replies and patience.

I've tried to change pedals, played with chain tension... even lubricated it...

Scrod, is it possible that my BB spindle is a little longer and chainline is a little bit off..(visually it is hard to say... for me at least) . I noticed, while cranksets are the same on Langster and Kilo, that spindle on Kilo is shorter and I did not measure BB shells precisely but they look the same width..

Is it possible or known case ? Thanks in advance.
