Last year I bought a Jamis Allegro 3x for recreational and traveling purposes. Now I'm thinking of serious getting into cycling. So, I plan on upgrading my bike and getting some equipments. Therefore, I need everyone's expertise here.



Anyway, before I begin with the questions, I would like to say that I'm still using stock parts on my bike. Here's a link to my bike:

First of all, what I want to do is try to swap out some parts so I can make my bike go faster. I've asked around a bit, I was told to upgrade to new wheels, crank set, hubs, or tire (This came from several different people). I actually don't mind doing all of the above or at least most of it if prices are reasonable. I would like to know what you guys would recommend me to get (please do list the exact part name and the price, model number <-- if possible).



For the tires. I do plan on swapping them for thinner tires sooner or later regardless of my upgrade. So, what type of tires should I get? And what size do you guys recommend?



I plan on losing the suspension fork. So I need some help choosing one. I do plan on keeping the disc breaks. Also, what would you guys recommend, aluminum or carbon fiber? For CF forks, I was told to get a Winwood, what do you guys think of that?



Also, what type of bottle cage is recommended? What do you guys think of this one: http://www.performancebike.com/bikes..._20000_400027?



I also need help choosing a bottle too. Preferable something that is 20oz + and can fit on most bottle cage. Also, I do notice some bottles have gel, may I ask what the heck is that?



Now, that concludes all my questions for now. I hope it's not too many questions and they don't sound too newbish.
