The junior Speed range features Innegra technology, providing greater stability and reduced vibration (up to 17%!), while also lightening the frame to make it more comfortable for youngsters to swing.   A DAMPPlus insert, meanwhile, stops vibrations from travelling up the grip into the arm, giving an accurate feel and further upping the comfort factor – it’s all about making hitting the ball enjoyable and fun.  At 200 grams unstrung, the Speed 21 is suitable for four to six-year-olds, and features a closed 16\/17 string pattern to assist in the generation of power.","brand":"Head","offers":[{"title":"L0","offer_id":42887362183258,"sku":"2312873","price":20.0,"currency_code":"GBP","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0695\/5689\/5834\/files\/218077_main.jpg?v=1774359683","url":"https:\/\/www.prodirectsport.com\/products\/head-speed-21-white-black-boys-rackets-218077","provider":"Pro:Direct Sport","version":"1.0","type":"link"}
