So I apologize if this is the inappropriate forum but it seemed like the best place to go.
I'm looking to take up commuting via bike to work and just cycling in general. It's only about a 7 mile ride to work so I'd probably be putting in around 100 miles a week total.
One of my friends informed me to look for one with Shimano 105 parts and I found this one on Craigslist, which I assume is an older bike but I wanted to get some input on. I don't have much money at all to put down right now but I could always upgrade, so mainly just want to know if this would be a decent bike to get started with. Obviously I would go test ride it and such first but the seller is a ways away and I wanted to get an idea if it was worthy my time first.
Any input is appeciated.
