PILO D339 CNC gear mech hanger / derailleur hanger

Very good replacement, perfect fit

fitted perfectly

Fits nicely and solid. Used on ATT boardman TT bike. However where the deraillieur adjuster screw lands the hanger is curved, so the screw touches only at one point, rather than square. Pushing deraillieur back relative to original. So I had to (choose to) file the curve down so that it was square. (Yes I could have backed it off, and I potentially created a stress riser, but relative to the original, that part is slightly proud).
