I posted this in the Specialized forum, but got no response so I thought I'd try here. My wife has suddenly developed the hots for this bike. Looks like a perfect bike for her, but I'm concerned about the Brain suspension, which I'm not that familiar with. I do know there's strong opinions on both sides, but I'm wondering if anyone can speak to how well it works on this particular frame. She's an experienced older rider, not particularly aggressive, but she does ride some fairly technical single track. Thanks in advance.
