No more than a couple of years. It's Rob's "Goldan Era" old bike. It has GP Wilson dropouts and an early 90's wicked lite paint scheme. I just made a few changes to it when I got it; stem / bars / thumbshifters / saddle etc. It was my primary bike for over a year and then I built this:
It's been getting a bit dusty since then, though I've taken it out a few times in the past couple of weeks.
