I'm guessing this is an early ninetys sorentose and I don't even care. I hate this bike. It qualified numero uno in my post on best and worst buys of 2009. (as the worst) I've replaced the broken seat and spent more than it's worth on this POS. I robbed the bar extenders for my next grocery getter. Hopefully my luck is about to change, though. Tomorrow I have high hopes of trading it for an early eighties Peugeot Orient Express that's in pretty rough shape but definately worth salvaging. Wish me luck...
