Thanks for al the replies.
I have indeed heard from someone these Coronado's were cheaper replacement parts. That being said, I think they look very nice and there in a good general state. Replacing them for a similar type campagnolo would set me back for €80 and probably a set of pedals which isn't worth it for me.
I'm going to take my chances with a 'random' set of chainrings. I'm thinking of switching to 38or39 and 49 or 50, think this might make riding the bike a little easier.
I'll let you all know how it turned out and I'll post a picture of the finished product (in a while of course
)
