SRD Mk1

[Michael Russell]

Trying to find a source for an emergency derailleur hanger for my SRD Mk1 - for just in case of a really bad day. Figure you folks spinning a Sacks 3X7 dual drive know what I asking about. Thanks - mike

I certainly don’t know what you’re talking about. I’ve not come across a replacement derailleur hanger for a derailleur hanger that is not replaceable.

Actually, what you might want to search for instead is an alloy breakaway derailleur bolt. Used to be a thing so not sure if they can still be had new or NOS but definitely the way to go. That's what I rely on.

The bolt is designed to break before the drop out and/or derailleur. You simply remove the broken parts, install another bolt and away you go.

Thanks, forgot about that old school fix.  Located one of those bolts at my local bicycle coop. Happy trails!
