GEMINI RIGEL SRAM 8-bolt Carbon Chainring | Direct Mount, Road/Gravel

Forged carbon body, continuous fiber teeth  |  7075-T6 aluminum wear core  |  40 - 54T  |  SRAM, Race Face, Easton compatible  |  Handcrafted in Barcelona

Rigel's forged carbon body cuts weight without giving up stiffness. A wear-resistant 7075-T6 aluminium core sits at the chain contact area, protecting the carbon from the friction and wear that chain contact would otherwise cause. Gemini moulds continuous carbon fibre around each tooth, arranged concentrically around the metal core under more than 100 tons of pressure, a structural approach they say produces strength other carbon manufacturing methods can't match.

Each ring is handcrafted in Gemini's own Barcelona workshop. It's the result of more than three years of R&D, over 500 prototypes, and two international patent applications, made under one roof rather than outsourced.

Features

• Forged carbon body for reduced weight without sacrificing stiffness
  
  
• Continuous carbon fibre moulded around each tooth in a concentric structural pattern, rather than layered or CNC machined
  
  
• 7075-T6 aluminium tooth core transmits power and resists wear, while carbon covers it laterally to cut dynamic friction and chain noise
  
  
• Manufacturing process uses over 100 tons of controlled pressure for precision fibre placement
  
  
• Handcrafted in Gemini's Barcelona workshop
  
  
• Patent-pending construction, backed by two international patent applications
