Now, hear me out… Does your advertisement include keywords like “gravel bike” or “great fixie/single speed conversion”?
With an old mountain bike the market is very limited. Unfortunately, given the bicycle was only produced for one year I’m sure that makes it even more of an obscure market. I would either bill it as a retro-modern gravel bike, or sell it as a potential fixie conversion.
And, if push comes to shove, buy a gold chain and throw it on that bad boy. Take some sweet pictures of that gold chain action and make sure to include those keywords!
A bit of a tease, but some sound advise.
