NEW Front Derailleur Boss Locating Jig: This is a huge time-saver. Modern drivetrains require the FD boss accurately placed in accordance with their specs. This steel and aluminum jig places a front derailleur boss 9mm inboard of the BB face and 8.7mm forward of the seat tube centerline, while holding the boss parallel to the seat tube for brazing. Reversible plate allows for 1-1/8" and 1-1/4" seat tubes. Rod is 10mm diameter to match most front derailleurs. Always check the manufacturer's specs for proper FD boss location. Spring clamp not included. Most FD bosses will require some cold setting or filing to achieve the correct location, and this tools also acts as a quick gauge to determine whether the positioning is correct.
