Is there a low gear limit for these hubs? I have had a search but can find no info.

I have recently got one on a genesis. It will be going to the 'puffer as my mud bike so I was thinking of going really low on the gearing using a granny ring. I realise I would be spinning out at some ridiculously low speed but as I am soloing I doubt I will needing the higher gears, whereas I bet I will want the equivalent of the granny gears on the climbs. Thinking 26 chainring with the 18 sprocket.

Google not working near you then 😉

Thank you – your google-fu is obviously better than mine this morning

There is a fair chunk on Sheldon's site on alfines to 🙂

I run a 33×18 which is about the same as a 32×25 in bottom gear (I hardly ever use a granny on my triples). A 32×20 would be a fairly low – like a granny in all but the bottom couple of gears.
