I come at this as one who has built up and ridden suicide hubs (extensively), helped a lot of other people set them up and have never experienced a failure as long as those hubs were ridden within their limits.

I can't do this at my shop or our co-op because of liability issues but if someone is dead set on doing it this is how it goes.

You need to secure the cog and lockring with RED loctite and make sure things are torqued down as you won't be able to correct this after the loctite cures, rotafixing the cog into place is a really good idea.

After this the loctite needs to cure for 24 hours.

If you are a skidder this is not the set up you want as a suicide hub needs a brake.

Removing the cog and lock ring should require use of a torch and if you built it right getting the cog and lock ring off will be quite a chore... and there is still a high risk of messing up what might be a decent rear hub.

Don't do this to any nice vintage hubs... please.

I still ride one suicide hub... it has been going strong for 12,000 km and I have swapped the cog once and the wheelset has been used on a few of my bikes.

I know how safe they can be but I have also seen a lot of people mess them up.
