I'm looking at a 1988 49cm Palo Alto with Columbus Steel Tubing made by Biemmezeta. It has 27" x 13/16" tires, which puts it at a 30" standover height. That's 2 inches shy of being able to keep me "safe"
Can I put smaller tires, 650Bs maybe, to make this a shorter standover height?
I need the tires to be suitable for commuting / light touring.
Is it worth the cost?
What other gotchas are there?
