A2Z 10-Speed Upgrade Kit To 40T-AD-40T

The sprocket for the Shimano 10-speed rear cassette allows you to expand the range of gears so that you can comfortably climb using a 1x10 or 2x10 drive.

To prepare such a drive, you should use a detachable 10-speed cassette, remove one of the sprockets and add an A2Z sprocket in the extreme position at the hub body.

After installing the sprocket, the range of gears is the same as in the case of the most expensive 1x11 drives using economical 10-speed components.

CNC cut from 5mm thick 7075 T6 aluminum. The sprockets are available in sizes 40T and 42T. Each of them comes with a 16T steel sprocket, a washer and a nut. The additional sprocket allows you to compensate for the difference after removing one of the middle sprockets.
