Technical Specifications
Everything you want and nothing you don't, the X-Games-proven Fuse offers more bang for your buck than any other player in the game. Always bomb-proof, high integrity and ultra lightweight, with super-low BBs and compact drive options.
  • Fuse Kraton mid-flange grips for shock absorption and hand traction
  • Fast-rolling Rhythm Lite Sport tires keep grip levels high and wheel weights low
  • Compact drive 36/13t CNC-cut chainring for a stronger and lighter weight drivetrain
  • Frame with 19-inch top tube and externally relieved head tube may be built for Groms, but still takes tons of abuse
