Tiso launches wireless 12-speed electronic road group

 

Italian component firm Tiso today debuted its most ambitious offering yet: a wireless 12-speed electronic road group designed and built in-house. We've yet to lay our hands on it and are still awaiting further details but needless to say, it's an awfully intriguing development.

Tiso's brake/shift levers are laid out similar to Shimano's Di2 models with a pair of buttons situated around the bottom third of what looks to be an aluminum brake lever blade. Instead of two discrete buttons, though, Tiso is using a rocker-type switch.

From there, signals are sent via either "radio" signal (we assume some sort of coded 2.4gHz protocol) or Bluetooth to the derailleurs, both of which are connected – with wires – to a large down tube-mounted box housing the receiver, system 'brain', and a battery.

Tiso's teaser video also shows the use of a remote control, the purpose of which can only be speculated. However, its existence also suggests that it may be possible to mount satellite shifters at different locations on the bar, similar to what Shimano has done with Di2.

Tiso's group currently consists of the shifter/brake levers, the front and rear derailleurs, the wired control/battery box, and its own proprietary 12-speed cassette. It's unclear at this point what sort of cog spacing Tiso has used or what type of freehub body spline pattern it requires. However, Tiso does specifically mention that the system can be set to work with current Shimano, SRAM and Campagnolo 10- and 11-speed drivetrains, too.

We're currently waiting for pricing, official weights, and availability but given the wireless format and the additional hardware it requires (multiple batteries and multiple transmitters), we don't anticipate Tiso's group will be lighter than the latest versions from Shimano or Campagnolo.

could be ore issues when this is the norm, has to have its own unique code/encryption

chance of interference

 

and how we could have fun with a remote button hacked with someones coding
