PS- also watch out for stolen bikes if you are buying new. At the same time I was looking for the Roam, I found a really nice Trek DS8.3, also 1 year old. Something about the seller seemed fishy to me though, looking at the pictures of his household in the background, and his other items for sale... he had about a half dozen $1000-$2000 bikes for sale, and the photos showed a very dingy environment. I was leery about someone like that having so many high end bikes to sell, and he also had a bunch of X-box units, gold jewlery, etc.

I asked for the serial number and he was dumb enough to provide it to me, I looked it up on the police database and it came back "STOLEN". So I didn't buy it obviously.

If I had, likely the first time I took it into a shop, when they logged the serial number into their service database, it would have flagged to them too, and they would have probably turned it over to the police and I would be out the $ I paid for it.

So just be careful if you are buying used. You never know. The gal I bought my Roam from gave me the original store receipt for it along with the purchase. That made me feel much more secure.
