Before I buy a Surly one, does anyone have a 21T single speed cog to fit an HG cassette languishing in their parts box that they want to sell or trade? Condition not that important, it's not going to do big mileage.

I'd recommend Andel sproks - allegedly the same as Surly but cheaper - I get mine from velosolo.co.uk
Apologies, I only have one 21T on the bike and it's looking a bit shagged....

Good info, thanks.

Hello

I might have one in my parts bin, I only use my SS to ride to work on and there is only one hill ( I am being kind lump ). So I use a 17. I will check later to make sure it's a 21t



Cheers Stuart

Hi

I have looked and it's a 20t if that's any good

I'm running a 19T already and wanted to go twiddly so I reckon I'm going to buy an Andel 21T one from velosolo, but if your 20T is cheap I might take it off your hands as well. PM me a price.
