Don’t know much about the Spitfire as I’ve not ridden one. I do own a Rocket though and it’s an absolute riot of a bike. Ok, the suspension design is not the most sophisticated I’ve ever ridden but I can honestly say that in 15 years of mountain biking its the best bike I’ve ever had the pleasure to ride in terms of fun. It’s fast, agile, pedals great, flies out of corners, did I mention that its fun?!, stiff, chuckable, very poppy, fun, fun and more fun. Getting the idea? Not as composed in slow, techy rocky stuff as say a vpp bike but its a blast once you crank it up.
Get the Rocket with either CTD or BOS option.
