To say that Redline's D660 is a great bike ready to tear up the trails would be a huge pleonasm. It starts with a double-butted hydroformed aluminum frame and adds a 100mm-travel RockShox Reba RL fork with a tapered steerer for outstanding stiffness. Keeping it all rolling is a sweet set of 29-inch wheels wrapped with grippy WTB tires. Plus, the D660 boasts a smooth-shifting 2x9 SRAM X9 drivetrain and well-modulated Avid Elixir hydraulic disc brakes. Hop on the pedals and start exploring on your new Redline D660.
