Xlab Saturn 5 Disc Wheel with Ceramic Titanium Technology (C.T.T.) this proven wheel has been given a tremendous speed boost with 4 full Ceramic bearings. Each bearing has solid ceramic balls and titanium hard coated races resulting in up to a 14 minute savings or 4% faster over an Ironman distance race.

     Cassette Body 7075-T6 Aluminum Alloy. 2 Ceramic Bearings 6 Pawl design for fast and smooth engagement Shimano/SRAM or Campagnolo Compatible

     Ceramic Bearings Up to 4% faster or 40 meters per kilometer gain. Up to 60% less friction. 60% lighter than steel bearings. Up to 20% stiffer than steel bearings.

     Bearing Races Ultra low friction titanium coated bearing races. Bearing Balls Full ceramic not hybrid. Composed of solid Si3N4.

     Low Drag Convex Design Flat discs are the best for indoor use or on a totally windless day where only the minimal frontal area and low friction surface is important aerodynamically speaking.  However, when the wind is coming from the side, even just 5°, the air has a harder time staying in contact with the surface of the disc. Convex shaped wheels generally perform better in these conditions because the air does not have to ‘bend’ as much as with a flat disc to stay in contact with the disc surface.

     Superlight Hubs The super lightweight rear cassette hub shaves the weight even further, down to an incredible 1039 grams for the 700c tubular disc. 

     Low Drag Disc Finish the discs have a new gloss finish greatly reducing friction compared with other wheels and yet we have been able to even reduce weight due to the latest carbon fiber technology.

     Weights   Rear 700c Tubular 1039g , and 700c Clincher 1199g
