Jamis Dragonfly Review: Converting a Commuter

Jan 2019 · Miles Arbour

The Jamis Dragonfly Sport is designed around 26+ tires, adjustable sliding dropouts, and a Reynolds 520 steel frame. Here is our complete review...

Highs
  • Great geometry that lends itself to a comfortable and upright rider position, great for newer riders.

  • Enough mounts considering the frame size, including standard bottle mount, downtube bottle mount, and rear rack mounts.

  • 26+ tires are great for smaller riders, and make sense for the target market.

  • Affordable but still spec’d appropriately.

Lows
  • Pretty heavy even without gear. Super heavy when loaded gear or rear rack.

  • Tire and rim combination is crazy tight and downright frustrating to remove.

  • Colour may not be for everyone.
