This frame is designed to accommodate up to 26 x 5.0″ tires on 80mm rims or 29 x 3.0″ tires on 50mm rims, and features a tapered (44/56mm) head tube. Standard rear dropout spacing is 170mm, with optional 177x12mm and 197x12mm available (our builds use 197x12mm thru axle rear hubs).
The Ventana El Gran Jefe is available in 2 standard sizes (geometry info below) and 2 standard colors: Grinch Green or Mango Tango. Optional semi-custom colors also available as well.
