Hi all
Currently building a 10speed hard tail using cotic Solaris frame. The frame was purchased 2nd hand and came with a rear hanger already fitted.
I have gone to bolt on a shimano xt Deore rear derailleur and can't get it to fit. Basically it hits the smallest sprocket stopping me being able to line up the mounting hole.
Tried pulling the derailleur into its position when being used but this doesn't change the position of the part of derailleur that is fouling the sprocket.
Are hangers bike specific, derailleur specific or number of speed specific? Any guidance appreciated
