Rare Vintage 1999 Schwinn S-10 Carbon Mountain Bike. I measured the distance from the center of the crank to top of seat tube (including chrome ring) and believe it is a 21” bike.

Comes as pictured - probably will need a new inner tube on one tire. I am not a Schwinn expert so I may be wrong on the year it was made. There are 2 serial numbers that I see when I turn the bike over - one is K8070293 (on the red section above the crank housing the other on the silver colored crank housing is F980981. The interweb Schwinn info is confusing at best - if I am wrong on the date please LMK. There are a few dings and it could use a bath.

Shipping will be $140 in the lower 48 states or pick it up for free. It may need to ship in several boxes as oversize packages are crazy expensive to ship.
