For an even more unbiased view of creatine, and how to use it, check this fact page from the Australian Institute of Sport. They don't manufacture creatine (as far as I know).

Personally, I wouldn't bother with supplements (beyond decent carb drinks, gels, and a protein recovery drink) until you make Cat3 or better. Until then, there are other way more important habits to learn (like how to train, how to recover, how to corner, etc etc).
