BOS Dizzy 27.5” Fork – Black and Gold

The 650b version of the Dizzy fork from BOS allows you to introduce the lightweight, fantastic damping ability to your 27.5” wheeled bike. 3-position compression adjustment and fantastic damping mean that this fork can be set up to your ideal style and weight.

Thanks to the travel options the Dizzy 650b fork can be fitted on a whole host of bikes or different styles such as the 120mm fork on the 650b Santa Cruz Highball or the 140mm fork on either the Santa Cruz 5010 or Juliana Furtado.

MBUK featured the Dizzy fork where it scored 4.5/5 stars and the tester stated that the Dizzy “resets the benchmark for short fork benchmark with its XC weight that can be ridden as aggressively as most enduro forks on the market” which again shows the Dizzy’s superb versatility.
