I'm looking at selling my 2010 Giant Boulder and have been told a local shop can appraise it and possibly buy it off me. If I choose to go the PinkBike route, what would you guys suggest it's worth? Great condition and I'd be selling it as a complete bike. I honestly am new to the mtb community and my bike has basically sat in the garage for 3 years. Help on determining a good selling price would be greatly appreciated, thanks!
