Those are ALL shill reviews, trust me.
1) RBO sells the Gavin.
2) I've seen those identical reviews plastered on other websites talking about the Gavin. Don't trust any reviews for RBO bikes unless it's by someone on a forum with more than just one post. For example, I know there are legit reviews on both bikeforums and roadbikereview forums. Use Google search if you can't find it; it tends to be more reliable than the built-in forum search.
