Sorry, "road link" phraze confused me, I didn't understand that's hanger extender.Catagory6 wrote: yeah, i have one of those. but the OP stated specifically WITHOUT a road link.
that's what i'm interested in
Unfortunately, there is no standard on derailleur hanger length. So, what works on one frame will not work on the other. It all depends with which hanger has manufacturer designed frameset. I never had enough time to research if there are longer hangers with the same arrangement of screws and shape to fit certain frame, bit if there are this could be a life saver.
Also, not every hub will position sprockets at the same place, if they are more to the inside, derailleur can go up to bigger sprockets. My old Veloce hub and new Record/Bora hubs place sprockets differently for about an mm or two, which is half of the cog pitch.
What can be done to help, but might reduce shifting quality, is:
- Change upper pully to the one with less teeth to reduce its radius and create some space between pulley and cog. This usually means to use 10 teeth pulley instead 11. If it is little wide it can be sanded.
- Deliberatley bend hanger for few degrees so that angle of derailleur allows more space between upper pulley and last cog. One has to have a good measure here between acceptable shifting experience and needed distance. I have hanger tool and keep my hangers perfectly straight, but when I check other peoples hangers, they are all over the place and still derailleurs are working somehow....so why not use this tolerance to create additional mm or two where we need.
- Just use hanger extender. This might give some flex to hanger and also make shifting less optimal.
