Would like a 29T or 30T uno ring (or equivalent) – googling suggests they exist, but cant find any anywhere. Any suggestions, or alternatives?

Might be worth contacting RJC Extreme they list 32 to 38t Uno rings but no 30t

Activesport2011 on eBay do them and all Middleburn stuff. It’s Mark Anthony IIRC

You have not said whether its for square taper cranks or not – you can get a 30T UNO for the external bb version but not the square taper cranks – or not at least from Middleburn. Have a word with Matt as i know he was thinking of doing some for the square taper.

thanks – it’s for the older (RS7?) sq taper cranks

Try the 29 inner ring of the duo set up on its own?
That’s what I run on my alfine set up. Seems to have been ok so far.
