Green UO-8
Wow. So little UO-8 love. I think they are great bikes. This one has a leather saddle, big plus. To give some perspective, I recently sold my UO-8 for $250. Upgraded with alloy wheels and a well used Brooks Pro. Other than that it was stock, including the Simplex derailleurs.
Sounds like a deal at $125. Make sure it fits you. Really cant go wrong with a UO-8. It is the king of Bike Boom bikes.
