Excuse the mud, it's been storming here in Amsterdam for the last few days!

Thanks!

Take out the crank arm and see if there are some numbers written on BB cups: 35 x 1 (french and swiss) , they are the same, except thread direction of the RIGHT CUP (drive side): French - right (clockwise) ; Swiss: COUNTERCLOCKWISE.

I hope this hekp.
