Sram has now launched the world's first 12-speed wireless electronic gear group for racing - AXS.

The group brews on the technology from their well-tested and super well-functioning Etap technology.

The system is the fastest gear change Sram has made so far, just as the group is easier to set up easier to maintain than cable systems, and of course it just gives the bike a much cleaner look.

The set is easy to put on a bike and is easier than ever since no cables have to be pulled and the setting is made on Sram's app.

The upgrade groupset comes singlespeed ready, but an app-settable front derailleur can be added if you want to expand it.

The group is made up of:

Rear derailleur and shift brake lever.

The rear derailleur is wireless and lighter than ever.

Comes with battery.

It is narrower so that it can withstand crashes better and sits closer to the bike.

The shifters are wireless and have more options than before.

Can be set via Sram's app.

The group comes with a charger, guide and setting tool.
