I’ve got a ’14 Five with a Pike and a CCDB air. It’s a fantastic bike. The shock makes all the difference. I think it feels like a much bigger bike, a bit like my ’11 Enduro that had 160mm f&r, but pedals really well. I’d be tempted to go down a class in spec and then upgrade fork and shock to something better.
Frame, fork, shock and wheels are the most important component (IMHO).
