It all depends on condition, size, and original components...
Below are some ebay comps... for bridgestone mb 1... one recently sold for a crazy $850 but was near mint
Average is between $300 to $400 for complete and original bike in a med to large size
Frames go for between $100 to $200 depending on condition
Hope that helps... are you going to ride it or sell?
