my neighbor is selling her trek 7100 to get a road bike.....

It’s a 2008 model 17.5 inch bike (blue and silver) with 400 total miles; I can verify that with my computer.

So what do you think it is worth?

Get a road bike like she gets.

Put it on eBay with a reserve of list price. Obviously, it won't sell, but the highest bid you get is what it is worth.

My guess is less than $200. Just looked at two completed auctions on ebay and one ended at 172.50 the other 163.25, same bike, neither sold as reserve was higher.

lets play nice......I just got my first road bike. she can not keep up with me, that is why she is selling.

maybe $200, i wouldn't go higher.

i think her feelings are hurt, for selling that low so soon after she purchased it....she is gonna keep it or the rain days.

Local Craig's List had a men's Trek 7500 in good shape a little older for ~$300. Saw it on there again a month later listed at $200.

Since the consensus seems to be relatively low at <$200, why not consider keeping it as a 'beater' bike? Ie, good for some light trail or rainy day workouts, trips to the beach etc. If the roadie's in for maintenance, she's still good-to-go.

And what roadie doesn't have at least two bikes?

I totally agree. She is going to keep it for rainy days.....at the very least keep it to ride on some of the nonpaved walking trails AND when ever it rains.
