I had fruitless search for CJ's gear tables in the cUK stuff. IIRC I'm fairly sure that his explanatory notes included the point that 700C should be treated as 27". Decades ago, a loose-leaf version of the CTC handbook had a chart with chainwheel teeth down one side and sprocket teeth down the other. You could calculate gears well enough for most purposes by laying a ruler across. I made some photocopies so I could draw in those lines for a visual comparison of whole freewheel blocks.

That's a ten year old thread on gear calculators. A post from me about the printed chart is on p 2

https://road.cc/content/news/updated-sh ... nue-284033. Ah, the hand-wringing. It seems to have started with a post on the road.cc blog by someone who posted an inquiry here but didn't wait for our response.
Harris Cyclery has closed after a 70-year run, hit hard by pandemic supply issues.
Sheldonbrown.com got its start when Sheldon worked at Harris Cyclery, and we are very grateful to Harris Cyclery for its support. But, since 2010, sheldonbrown.com
(except for the /harris pages) has floated its own boat, through online advertising.
We don't know yet what other affiliation we may find, or whether we'll go it alone, but you may rest easy. Ride your bike, and feel free to come to us for help keeping it in top shape.
Whatever I am, wherever I am, this is me. This is my life
