The Raceway is a carbon fiber cross set with 28 diamonds. This is solid, machined carbon fiber people. In person it feels like wood from outer-space. Its incredible. The streamlined diamond detail sets it off. For something with such simple lines this piece has so much amazing detail. Its about 33mm long so not to small, but not to big. Perfect everyday wear. Includes a 24" rolo chain. Please note that because this item is carbon fiber no two will be exactly alike.
