Subject: [CR]Head lug extensions_ standover height and fit

A fellow listmember observed the extensions on the newer head lugs and asked why not have a longer seat tube.

Back in the day at the Schwinn shop fit was determined by the largest frame one could straddle. By that method I was a 57 or 58 cm measured c -t - c depending on the drop of the bottom bracket and the seat tube angle. Since I have aged a bit I have been interested in bigger tires. Add a cm or so for big air and the top tube is too close and personal.

My daily rider is a 56cm to accommodate the bigger tires but the handlebars ends up lower. Since my back is a little stiffer I switched to a sloped stem.

A extension would accommodate all of the above and still allow for a traditional stem. I wrench at a modern Schwinn shop occasionally and they fit much smaller than in the day. Rivendell uses a slightly sloping top tube and an extension. Serotta markets an extension. Any thoughts on standover height and fit?????
