SRAM have lifted the lid on their groundbreaking new wireless groupset. It's called SRAM Red eTap and Si Richardson talks us through the details. Subscribe to GCN: http://gcn.eu/SubscribeToGCN
It was all the way back in May of 2014 when Tom Last first spotted an electronic SRAM Groupset at the Tour of California.
SRAM have spent the following 15 months refining this revolutionary completely wireless groupset. Well now, it's finished, and Si Richardson was the lucky person from GCN to take a first look, and bring you all the details.
The derailleurs communicate with the shifters using 128 Bit AES encryption. All components therefore need their own batteries but SRAM have designed them to be easily removable.
The method of shifting has also changed, with each hand responsible for either shifting up or down the cassette, and when both levers are pressed simultaneously the front derailleur is activated.
