That kinda depends on which fork you already have. Looking at the Specialized website it looks like there's two Rockhopper 29er models. If you have the Rockhopper with the Tora fork then that's more or less the same performance wise as the Rockshox Reba which has been one of the benchmark 29er forks for quite a while now. The main difference being that the Tora's a bit heavier due to more use of steel in place of lighter alloys. So if it's the case of a few grams I'd basically say - suck it up buddy . Right now your money is probably better spent elsewhere.tallB said:i'm new at this so i dont know exactly the kind of riding i'll be doing. i just got a rockhopper 29er and i hear the first thing to go is the fork. what forks would you seasoned riders suggest?
