Saved a vintage frame

ConsNeed to drill out the gear hanger threaded hole carefully.
This little device works when the thread on a gear hanger is stripped. I used it on a vintage steel frame where the hanger is an integral part of the frame. The hanger was less than 7mm wide but it worked together with a washer. There are other solutions to this problem but they involve brazing and cost a lot more.

ConsWatch chain clearance for smallest cog on cassette
ProsEasy and inexpensive way of saving frame
This very simple piece of kit solves a perennial problem - how to repair a stripped rear hanger thread in aluminium frames. (And steel too - although this is less likely).
The only thing to note is the shoulder which then protrudes on the inside of the hanger hole may prevent chain picking up the top gear (smallest cog) on the cassette. In which case it may be necessary to add a shim to the axle to maintain chain clearance...
Works Well

Enlarged the hole for the mech & fitted this bolt. It does the job well & saves the need for an expensive frame modification.

Does Your Dropout Frame Saver Come In Different Lenghts?
30 Jan 2015
My dropouts are 7mm thick do you sell one that would fit this frame

This dropout saver is designed for dropouts that are 7mm thick and above, so it should be fine for use on your frame.

What Size Thread Is This For?
17 Jan 2015
I have a rear derailer that have stripped the thread out of the frame. what size is the internal thread of these drop out savers?

These are threaded internally to take a M10 bolt which is what is used by the bolt on most rear derailleurs.
