Ahead standard models all feature a metal alloy handle and a shaft that runs the full length of the stick. A super-hard polyurethane cover protects the main playing surface and is replaceable. Ahead sticks give you more power for less effort and 50% less shock than wooden sticks, lasting 6 to 10 times longer than their standard wooden contemporaries. The precision alloy core guarantees weight and balance variations of less than 1%, compared to as much as 20% with wood. Super hard polyurethane replacement covers protect your sticks and your gear. To get the best usage from your Ahead sticks it is vitally important to replace the covers before they wear through to the metal. Worn out covers reduce the durability of Ahead sticks by 75%!
