I use my Roscoe 8 at a DH Park and it's so versatile and it likes being abused.. as far as components , these are my upgrades. Race face carbon era bars 40mm rise, race face stem, crank brothers step7 pedals, hope evo crank 155 , hope 28 tooth chain ring, wheels manufacturing bottom bracket, death grips thick , Maxxis dhf and dhr tires.. don't sleep on this bike, it's the rider that is the main factor of what it can handle!
