Description

• Colnago CLX Signature – S# GC8 JA149 – Carbon/Black

  “Carbon Legacy” A true collector’s piece, this Colnago CLX bears the signature of cycling legend Ernesto Colnago. Serial number GC8 JA149 marks this as part of Colnago’s prestigious carbon fiber evolution, representing a pivotal moment when traditional Italian craftsmanship embraced cutting-edge materials.

  The Ride

  A masterpiece of early carbon engineering, the CLX showcases Colnago’s sophisticated monocoque front triangle with bonded rear stays – a cutting-edge manufacturing technique for its era. The frame features strategically variable carbon layup patterns, with reinforced high-stress areas and carefully tuned compliance zones. Its asymmetric chainstay design and integrated cable routing showcase how Colnago mastered modern materials while preserving their signature stable handling. The carefully designed tube shapes and legendary bottom bracket stiffness create a ride that’s both responsive and sophisticated, transforming each ride into an experience that transcends mere cycling.

  Condition

  Frame is structurally sound with no cracks or repairs. Shows signs of regular use with cosmetic wear including notable chips on the top tube, downtube, and chainstay. All wear points are cosmetic only and do not affect the frame’s integrity or performance.

  Workshop Wisdom

  The integrated headset system uses Colnago’s proprietary compression design, eliminating the need for a traditional star nut while providing superior bearing alignment.
