Using 6mm bolts on a thorn sherpa?
« on: February 07, 2010, 05:21:58 PM »
Hello,

according to various places rear racks can take a lot more weight if they are attached with 6mm bolts, but my sherpa only has 5mm holes in the rear dropouts.

Is it possible to use a tap to cut a 6mm thread without damaging the frame?

I have done this with my rohloff exp.

The sherpa rear dropout rack point would need sufficient material round the 5 to 6mm hole - does yours look like it is part of a bigger forged dropout - if so have a go.

I got a set of taps from here.
