Question about frame size

I'm looking at a used bike and the guy said: "From the top of the crossbar to the middle of the crank is 28 1/2" I believe" Is this a HUGE bike?

Depends on how bikesmart the guy is!

I ride a 58 cm bike at 6'1....It measures 21.5 from the toptube to the center of the crank (which is the bottom bracket)

BUT!...IOf I place the pedal in the down position and measure from the toptube to the center of the pedal spindle, it's 28 inches.

Since the dude doesn't know the size, maybe he also doesn't know what the crank is. Maybe he's thinking it's the center of the pedal (spindle)?

You osme people don't know proper bike lingo!

If the measurement were true, yes, it'd be a huge bike (a 25" bike is a huge bike, 27" is enormous, 28.5" would be NBA level) The size is measured wrong and the information you are getting is useless.

This is one of those questions that screams 'Don't buy!' If you don't know how big a bike you need or you don't know how to fit the bike, do yourself a favor and go to a shop. Buy a new bike. They'll adjust it for you, give you free adjustments for X amount of time, and save you some money in the long run. (See my other post in this forum on used bikes.)
