Looking for an all-around bike for fitness, commuting and a day in the country? Look no further than the budget-friendly K2® Astral 3.0!

  • Astral 3.0 does it all, with road-bike geometry and an upright ride that promises swift cruising speeds and a day free of back and neck pain
  • K2 Reflex Road frame, constructed of 6061-grade aluminum, is shy on weight but big on muscle
  • Aluminum frames are vertically stiff; stiff frames transmit leg power efficiently, which in turn aids quick acceleration and rapid climbing
  • Flat handlebar/rising stem design places rider in an upright position; this in turn reduces strain to hands, back and neck and increases visibility
  • Kinesis straight-bladed, aluminum front fork provides solid steering
  • Shimano Nexave front derailleur and SRAM shifters, cassette and rear derailleur provide responsive shifting through all 24 speeds
  • Efficient SR Suntour crankset transmits all your pushing power to the rear wheel; triple chainrings give you the versatility to rule hills and flats
  • 700c wheelset and tires provide a smooth ''big wheel'' ride that cruises well and minimizes small bumps in the road
  • Grab the ergonomic bar ends (attached at each end of the handlebar) when hard climbs require you stand and crunch the pedals
  • No fancy shoes required—just get on ride; shock-absorbing platform pedals accept most casual shoes
  • K2 Sport Fitness saddle is gel padded for day-long comfort

After its initial break-in period you might notice your bicycle performing less responsively than the day you brought it home. Not to worry, this is typical of all new bicycles and simply reflects that cables have stretched or their housings have seated themselves into final position. To keep running at peak performance, all REI bicycles come with a FREE warranty tune-up, which should be accomplished between the first 100-200 miles of riding or after the first two months if you're accumulating miles less quickly. Contact your nearest REI bike shop for details and an appointment for this important service.
