The 2007 GRAY tubular disc wheel is one of the strongest, aerodynamically efficient in the industry. Most of our athletes agree, it is one of the lightest and fastest disc wheels available. The aerodynamic advantage of a disc over a similiarly weighted rear wheel are staggering and the low perimeter mass of our disc redefines quick acceleration and maintains top-end speed. Our disc hub is designed to be Shimano or Campagnolo compatible and can be converted for track with a track axle kit – fantastic adaptability. Purchase a GRAY Disc wheel and notice the difference. Type: 700c tubular Hub: Shimano – (Campagnolo available upon request)
