Alright so I am just starting to get into mountain biking and I am about to purchase my first good bike. I have found a Specialized Rock Hopper on craigslist for a decent price and it looks like a really good bike. For the most part i will be riding trails but I also really enjoy hitting jumps and doing drop offs and I just want to know if the Rock Hopper is good for that type of stuff and can withstand the punishment. If not, what would you recommend for a beginner for the type of riding I want to do? Any advice would be appreciated.
