Review and Buy Junior Tennis Racquets from Babolat, Dunlop, Head & Wilson. Most manufacturers use Aluminium to make junior tennis racquets especially those for the younger kids. Aluminium or Alloy is a great composite and allows the pricing to stay low. As the racquets increase with price so too will the composite they're made from. Metals will increase in quality from Aluminium, Alloy, Carbon through to Graphite. In most cases 2 of these will be used to keep down pricing i.e. The better Graphite might be used on the hoop to improve quality and strength with perhaps Alloy used in the handle where its less important. This will be more obvious towards the 25" sizing with most 26" containing some mixture of Carbon or Graphite. For the smaller racquets we have commented as to what age they would be suitable for but please remember this is just a guide and should always be adjusted depending on your childs ability & strengths. All racquets come with their original covers
