Found a 17.5 trek 9.8 hardtail for $350... is it just me or is that a steal. The bike might be a little small for me, not sure yet but I could always flip it. Am I missing something? Will probably have a look at it today.

Thanks

Hard to tell, a quick look on eBay shows early models selling for $6-700.

Which year? the model name has been in use since 2000, if a 2000 model, with no disc mounts, even though it was a high end model to start with, there will be little demand today, add to that, it's 26" which is out of fashion now, A high end bike will also have been ridden (or at least should have been) so components could be worn out.

If it doesn't fit, will it be worth your time to flip it?

x2 it all depends on the year
