Advice/ User Knowledge.
I'm looking to replacing my rear cog, for one that has been machined rather than pressed and so runs true.
All thoughts are welcome.

EAI strike the right balance between quality and price for me. Hubjub do them, I expect other places sell them too.

I've found the velosolo own to be pretty well round. from a sample of two of the aluminium ones though so not extensive research.

EAI are the safest option.  Surly also seem OK but tbh I've only run one on a Sturmey-Archer hub (which takes fixed screw-on sprockets, if you happen to have a threaded driver, but of course has a freewheel and is therefore more forgiving).
Hard work sometimes pays off in the end, but laziness ALWAYS pays off NOW.

I like the Andel sprockets. I prefer their teeth profile and finish over the standard EAI ones.

I quite like the Shimano DA one.  It's not too pricey and lasts for years (current one is 7 years old and out lasted two rims)

Having seen the state of the 18T Surly cog on my bike I've come to the conclusion it needs replacing. The current cog has done over 13,000 km of audax rides, including x1 PBP and x2 LEL, plus all the "normal" rides, so I don't think I can complain too much.
What on earth am I doing here on this beautiful day?! This is the only life I've got!!
