Can anyone offer a little help with bike sizing... I have an early 80's Raleigh Road Ace I'm thinking of selling and want to size it accurately before I place an advert.
As usual, lots of conflicting information on the internet as to the accepted method!
If no one can decide then just measure centre to top of seat tube.
or Centre to centre of the top tube.
or I know some people like to measure centre to top of the top tube.
how you measure. Shouldn't be too hard for them to add a cm or so from a picture to make it their preferred measurement.
and as for the rest, just measure and quote
how you measured it.
