Carbon ST Dart Stems By Harrows

Following extensive research and development at Harrows HQ, we are delighted to finally be able to share our new range of shafts with the world, Carbon ST.

An incredible amount of work has gone into designing and manufacturing these new shafts, perfecting all elements of the product to ensure optimum performance.

Unlike anything else on the market, the Carbon ST breaks the boundaries of what players expect a dart shaft to look and feel like.

A tough carbon composite structure is dual injection moulded with high quality polycarbonate material, resulting in this truly unique shaft.

Not only does this shaft look great, it has also been specifically designed to improve some key performance aspects of a regular shaft:

• Unique shaft profile directs airflow around the dart when thrown, producing a more stabilised flight path than regular shafts.   
• Flight lead-in has been redesigned with rounded edges to make fitting the flight easier and also reduce deflections when hit.
• The tough carbon composite structure significantly increases the strength of the shaft, reducing damage and breakages.
• New Pyramid ring is larger and more streamlined, increasing durability and decreasing deflections.
• Angular polycarbonate sections protrude, allowing light to enter and refract, making the darts more visible in the board.
  

The Carbon ST shafts are available in 10 striking colour combinations and all colours are available in Short, Midi and Medium length.

Dimensions

Medium 47mm

Midi 40mm
