That's a nice bike! How much life is in your current bike? If it's going to need a major overhaul in the near future I'd give some serious thought to that Fuel.
I've bought at least one bike that I really didn't need (my own FS bike). I have no regrets, but I'll be frank, I had the money for it wuthout any worries. If your finances are tight, or if you're skimping on any other finacial goals, then sleep on it. But I'm pretty conservative when it comes to spending.
Live with intention. Walk to the edge. Listen hard. Practice wellness. Play with abandon. Laugh. Choose with no regret. Continue to learn. Appreciate your friends. Do what you love. Live as if this is all there is.
