Summary

The Knolly Endorphin is a highly versatile enduro bike, praised for its size-specific chainstays and re-tuned suspension that enhances pedaling efficiency and bottom-out resistance. Its design caters to smaller riders with a new XS frame size, while maintaining a playful and maneuverable ride quality. The bike's one-piece Monolink rocker link and Enduro bearings in every pivot point contribute to its durability and rigidity.

Pros
  • Size-specific chainstays for improved fit

  • Re-tuned suspension for better pedalling efficiency and bottom-out resistance

  • One-piece Monolink rocker link for increased rigidity

  • Enduro bearings in every pivot point for durability

  • Versatile with options for mullet or full 27.5" wheels

Cons
  • No XL frame size for taller riders

  • Fox 34 may feel nervous in steeper sections

  • 440mm reach may be outside comfort zone for some riders
