Boone Disc F/S 58 Plasma Grey Pearl

Ready to build your dream cross bike? Boone Disc frameset is built with ultralight 600 Series OCLV Carbon. It features a cyclocross-specific geometry, Rear IsoSpeed to smooth rough courses, and front and rear 12mm thru axle dropouts for better stiffness and handling.

• This bike was designed with input from cyclocross royalty, so you can trust it to handle everything from hurdles to sand pits
• Carbon rules on the cross course — its lighter, more forgiving, and more efficient than aluminum
• Rear IsoSpeed cuts down on the fatiguing impacts of rough courses and increases compliance, helping you ride stronger for longer
• Boones cross-specific geometry and tube shapes make shouldering easy so you can dominate all aspects of a race, including run-ups
• Seat mast cap (available in two lengths/two offsets) sold separately

IsoSpeed takes the edge off body-beating course bumps and gravel chatter so you can stay stronger longer, without giving up any pedaling efficiency.
