Specialites T.A. is a very well known, time-honoured French company. It has consistently upgraded its wide product range which includes water bottles, bottle cages, chainsets, chainrings, cranks and bottom brackets. TA rings, made from the best 7075 alloy, are cut on a lathe for perfect chain mesh, heat treated for extra long life and lazer engraved for future reference. There is a wide range of ring sizes for virtually every popular pattern of chainset. The clever Vega and Carmina chainset build system with a wide range of crank lengths underlines the specialist nature of TA.
