I got the following problem: The chain rubs against the front derailleur on the biggest front chain ring. The rubbing is really slightly and only when you put force on the pedals while riding. Nevertheless, this needs to be fixed. Because I'm a person that rather tries to understand the mechanics than bring it away for service I decided to mess with it.
Now here's the deal: I got the mechanics pretty much down from watching video's and a few hours of adjusting the FD. I found out that my FD just refuses to go outward any further. The limit screw has no use because I need to practically take it out in order to even get to the biggest chain ring.
Because I felt like I was doing something wrong I decided to completely remove the front derailleur and start from scratch. I got it to shift smoothly again but the problem of the slight rub against the FD remains no matter what I try.
So basically, the setting for the FD to go outward is maxed out and it refuses to go further no matter how much tension I put on the cable. Limit screw is already maxed out.
I'm using stock parts with the FD being: Shimano C-051. I can't find much info about it other than one site saying its compatible with 6/7 speed. According to this site (its in German but you should be able to make out the parts) I can pretty much make out that I have an 8 speed.
Anyone with some clear insight as to what is going on?
