im a complete noob to mtn biking and have been renting till now. I have 400$ to spend and cant decide between the Hardrock XC or trek 4300. I saw in another thread and asked if the Hardrock XC is the same frame as the rockhopper but got no response. I want a bike that i will beable to upgrade as i get better. Since the Hardrock XC is new this year, i think, i cant find any reviews on it. But ive read good things about the 4300. Ive have taken them both out for a spin and enjoyed them both. Anyone know what frame is better and will last longer. I dont wanna have to buy another bike for a LONG while, maybe just upgrade some components.
