2023 RONDO Ratt – Head-to-head in our all-road group test

Sep 2023 · Czajac

The RONDO Ratt CF is the furthest thing from a sensible all-purpose cruiser. Instead, it’s a bike for extremes, having fun, and cycling fanatics, but is it a good all-road bike?

Highs
  • Idiosyncratic design and concept, 650B tires, and focused on fun

  • A hoot on descents and fast terrain

  • Great bike for a reasonable price

Lows
  • Below average climbing performance
