The trails by my house are going to waste.
My dad bought me a Costco mountain bike. The Northrock xc6 a year or two ago but I havent ridden it. I read a review on it that said it was a decent entry level bike. Now that I want to get into mountain biking I was wondering if I need to swap or upgrade anything before hitting the trails. Or if its good enough to be ridden as it is and just replace things when they need to be replaced.
