Front derailleur and fender interference

Have some VO fenders that I got on sale a couple of years ago. They were mounted on a fixed gear, but now wanted to put them on the Dawes Galaxy I am rebuilding. Test fit , bolt up, good fender line ect, BUT when shifting the front derailleur to the big ring, the arm on the derailleur along with the socket head bolt that anchors the cable runs into the fender. And not just a little bit. Derailleur is a Shimano Deore for a triple.

I assume that others have had this happen. So, what are my options, other then narrowing the fender from the contact area down?

You might need to file/grind a notch into the fender to allow the FD to do its thing. (Or switch to bigger chainrings/shorter BB spindle.)

Got a pic?

I bought some VO fenders a while back for one of my old Raleigh Records. There was no way to get the rear fender on and still have enough room to slide the wheel forward to remove it. The fd was a Suntour Compe-V, which sort of sticks out behind the seat tube quite a bit. I ended up changing the Suntour to a Huret-made Schwinn Approved fd. You might have to look for a fd that just gives a little more clearance.

Can also use a front derailleur with a more narrow width. Most older Suntour Cyclone or Vx will shift a triple with no problem if you are using a friction setup. You really don't want to cut the fender if you don't have to. The rolled edge of the fender it what gives it it rigidity and provides support. If you cut it, there is a good chance it will crack from vibration, much faster than if you hadn't.

I had a similar problem shifting to the little ring with Suntour XC Pro FD with VO fenders on my Bianchi Axis. I drilled a 0.25 in hole in the fender right where the contact was happening. That solved it.
