BMC's Alpenchallenge AC01 is efficient, fast, stylish, and low maintenance. It's road bike quick with a comfortable heads-up geometry and flat handlebars. A strong, lightweight, triple-butted aluminum frame helps you cruise over hills, and an aluminum fork provides precision handling. The 700c wheels are light, durable, and wrapped in grippy Continental tires. Meanwhile, an 8-speed internally-geared, belt-driven drivetrain provides all the low-maintenance gears you need. Shimano disc brakes ensure impressive stopping power in all conditions, plus the Alpenchallenge accommodates racks and fenders (sold separately) so you can ride regardless of weather. Plus, you get a Selle Royal saddle and BMC's handlebars, stem, and seatpost for comfort and control.

Gates Belt Drive Belt

Gates Belt Drive Cog

  • The belt drive system uses proven technology and has many advantages over the chain drive.
  • Smooth and quiet, belt drives require little to no maintenance. Just spray it down with a hose and go!
  • Belt drives don't need lube so your drivetrain stays clean. You won't have to worry about getting grease on your hands or clothing.
  • The debris ports in the cog let mud, water and snow pass through without clogging the drivetrain for smooth running in all conditions.
  • A belt is incredibly durable so you enjoy miles of maintenance-free pedaling.

Internal hub gearing is a gearing system built into the rear wheel hub. It allows you to shift at any time, even when not pedaling, like at a stop sign. Because the majority of parts are housed within the hub, the gearing mechanism is protected from weather and grime, and therefore requires almost no maintenance. Plus, with less external parts than a derailleur system, you’ll get consistently smooth, reliable shifts.
