Final drive should be 1:2.2 .... think I'm running 1:2.15 on my Harris (19t - 41t) with 17" wheels and it's a good compromise - will pull a bit taller as they're nice & light :wink:

There ain't much difference in rolling diameter between old 19" and modern 17" wheels as the newer tyres have a deeper section (apsect ratio or summink like that) :!:
