Sprockets and ratios !

Just to chat seeing this section of the forum is so quiet !!!!  :bueller: Took my bike in for new rubber as well as sprockets and chain and went up one tooth on the front sprocket.  Thought I may as well try it while it was being done and what a pleasure - lost a little bit of low speed oomph but she gets up to 160 km/h in a flash now and the revs have come down by 500 rpm in all the gears My fuel consumption has gone from 27 kms per litre to 30 !!!!  Happy with the result as it is mostly used on tar - will see how it affects slow speed gravel riding soon !!
