Are these available? Would like to slacken the head a little on my Inbred.

I doubt it, there isn’t much room to play with.

Works Components do one – here you go

I stand corrected 😉

I noticed a difference in my 5 spot with one of those.
Fiddly to fit but worth it.

Great, thanks. Pricey but worth it if it’s the only option to slacken by one degree.

Fitted a works one a couple of weeks ago and I think it’s noticable. Not sure about better, but different.

This is what you need:

It even tells you which one will suit your Inbred.
