How many links in the chain?

[ozigoo]

PDuck has the same 19T / 37T combo so I hope he's right.. could get the 117 link and break it up as suggested, but not sure if it is necessary.. If 111 links is less adjustment than 110 I'd probably do it, but it's all new ground for me... PD if you read this, when you say 'little adjustment' do you think 111 link's would be better or worse? Cheers
