New to the cricket bat market, there are three different types of Adidas cricket bats. The Libro is the lightest of the three.
The Libro is suitable for quick-handed batsman who play a lot of touch shots, rather than big hitters. That said, its light weight allows for tremendous bat speed, so you should still be peppering the boundaries in front of the wicket as well.
There are four grades of Libro bats: The Adidas Libro Club, the Adidas Libro County, the Adidas Libro Pro and the Adidas Libro Elite. It should be obvious which are the cheap Adidas cricket bats there.
Adidas also produce junior libro bats.
