Show no mercy at your local jump jam or skate park on Marin's Alcatraz. Its durable 4130-chromoly frame can take whatever you dish out. The beefy head tube junction keeps this rig feeling solid and the short chainstays provide impressive snap. Up front, Marzocchi's sweet Dirt Jumper fork smoothes terrain and soaks up ugly landings. Plus, Avid's Juicy discs give you awesome stop-on-a-dime power. And, this sweet steel steed sports tough 26-inch WTB wheels and beefy Maxxis tires. Plus, the singlespeed drivetrain means less maintenance and more playtime.
