If the biker does not want to convert to an 11-speed drivetrain straight away, but still wants to enjoy the benefits of the single chainring drivetrain, adapting a 10-speed drivetrain is an option. With conventional 10-speed cassettes, however, the largest sprocket with 36 teeth puts an end to smooth running. And this is where the accessories specialist A2Z comes into play:

With the AD-40T and AD-42T conversion kits, 10-speed cassettes can be converted to 40 and 42 teeth respectively. The kit from A2Z consists of an aluminum sprocket with 40 or 42 teeth, 1 CroMoly sprocket with 16 teeth and an aluminum cassette lockring. The price tag shows CHF 59, the scale at 40 teeth 71 grams and the choice of colors is black, red, blue and gold.

The supplier Primus Sports says about the conversion: "There are already many conversion kits on the market but thanks to the A2Z 16 tooth sprocket - where instead of the 15 and 17 tooth sprocket is mounted - which is supplied with this kit, allows more regular jumps between the sprockets than if you only change the large sprocket. Example of an 11-36 cassette converted with an AD-42T kit: 11/13/16/19/21/24/28/32/36/42. For optimal performance, it is recommended to mount the 42 tooth sprocket with an 11-36 cassette and the 40 tooth sprocket with an 11-34 cassette."
