Key Technology

1 The red clubface is made from 60 layers of carbon fibre that weigh just 26g, 40 per cent lighter than a titanium face of equivalent size, allowing it to be made 11 per cent larger than SIM2 and SIM2 Max.

2 A nano-texture on top creates a strong and flexible striking surface with the right amount of friction, optimising distance by improving launch conditions in both dry and wet environments.

3 The Stealth Plus (£499) has a 10g moveable weight; the Stealth (£469) is more forgiving and offers higher spin; and the Stealth HD (£469) offers extra draw bias.
