Steven inquired with the following post: I have a friend in Italy who would like to convert a Campagnolo NR crank
to a triple. If I remember correctly there was a list member who was willing and able to do this.
I f anybody has experience with this and can give me any indications, I would be appreciative.
Thanks, Steven Maasland Moorestown, NJ USA
Gary DellaRossa's response seems spot on: Steven, By far the easiiest way, simple enough for a home mechanic, is to beg, borrow, or whatever a NR triple crank, or other triple crank that uses a 144
bcd for the middle and outer rings (e.g., Avocet), and bolt it back-to-back to your NR double, using it as a template. It's easy then to locate the centers, and drill away. Mike Barry has done a number of these. I have a
couple. Lacking a triple crank, I guess you would have to create a template, perhaps using chainrings for patterns, which certainly complicates
things and may be best left to a machinist.
All the best!

Absent that: Pete Johnson has converted several for me (1-650-365-1536).
Of
course there are minor cosmetic differences between this conversion and
the
Campy factory NR. As I am sure most list members know another good way
to
go is with a triplizer chain ring that I believe Sheldon Brown (Harris
Cyclery) and Rivendell used to carry and this would not permanently
alter
the crank arm.
