For competitive club rides or centuries, the Cannondale Synapse Carbon 6 bike delivers powerful performance to demanding road bike enthusiasts.

  • Synapse carbon frame features optimized tube shaping and geometry to promote efficiency and handling
  • Carbon fork, seatpost, shaped chainstays and slightly bent seatstays employ Synapse Active Vibration Elimination (S.A.V.E.) technology to effectively dampen road vibration
  • Shimano Tiagra compact crankset with 9-speed cassette efficiently drives power across all gear combinations
  • Shimano Tiagra levers control Tiagra rear derailleur and Sora front derailleur for smooth, dependable shifting
  • Tektro R520 brakes provide reliable stopping power
  • Selle San Marco Ponza Power saddle is an Italian beauty sitting atop the carbon seatpost
  • Specs are subject to change

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.
