swap xtr front derailleur FD-M900/1

[jotun_de]

Hej,

would like to swap a XTR FD-M900 (downpull) or a XTR FD-M901 (toppull) front derailleur - both are ø 34.9 mm

into a

XTR FD-M900 (donpull) front derailleur in ø 31.8 mm

I'd take as well the shipping costs to switzerland.

Anybody out there?

Cheers
