advice needed

The top tube is usually measured centre to centre from the seat tube, along the top tube to the head tube (the bit that the forks fit into from underneath and the stem fits into from the top), so not quite as far as the handle bars.

Sounds like you have a job on your hands. I helped my Father in Law empty the workshop that had belonged to one of his friends. The chap was a retired electronics engineer and keen model engineer and the workshop was relatively tidy (for a workshop) but packed front to back and top to bottom with 50 years worth of accumulated 'useful' stuff.

Yes what Neil said, like so:



No they're not 64cm either - 25" or 64cm are huge bikes like these:



I'd say the Bridgestone looks like a 55cm or 56cm and the falcon a 53cm or 54cm.

Must have very mixed emotions sorting through all his stuff....

Good luck.

yes you were right the seat tube is 54cm and the top tube 55cm, i think does this sound about right?

not managed to find any pics of the Falcon? any links
