In case you were unaware, Wantage has a tennis shop called The Racket Factory in the Post Office Vaults.
The store is run by Richard Holmes, who was a professional tennis for many years. He has a wealth of experience of restringing rackets both on the professional circuit and in the Wantage/Grove area. If you’re thinking of changing your racket then Richard can offer you expert advice. There is also a free “demo programme”, whereby you can borrow a couple of rackets for four days to compare them.
