SRAM Red eTap is a Step Forward for Electronic Shifting

"It’s here: SRAM’s wireless electronic system, in development since 2011 and publicly raced by SRAM’s professional teams for over a year, is now officially official. "

"SRAM Red eTap - actual weights and installation" | Bike Radar

"... 75g lighter than Shimano Dura-Ace Di2 9070 for comparably configured setups."

"At the risk of stating the obvious, it is worth noting that, unlike Shimano and [Campagnolo’s] electronic system, there are no wires connecting the shifters to the derailleurs and a battery. This speeds up the installation process tremendously and results in a cleaner build."

SRAM RED eTap “The finish product is simply Brilliant” | Cycling Weekly

SRAM Red eTap is an excellent groupset that is the match of any other groupset on the market. It’s an absolute doddle to install and set up, and once it’s in place provides excellent shifting with a revolutionary shift logic. What’s more, with a recommended retail price of £2,060, SRAM Red eTap is almost a grand cheaper than Shimano Dura-Ace Di2, while also being lighter too.”

SRAM RED eTap - “Wonderful wireless shifting on race bike”.

“The large area in conjunction with the clear pressure point provides a safe operation in any situation - even when wearing thick winter gloves or strong vibrations. This part of the mechanical DoubleTap lever was a good idea.”

“This is it, the revolutionary RED eTap: a fast and smooth functioning electric circuit that works just how friends of SRAM groups dreamed it would.”

“Our expectations of the RED eTap were high - the system has met the practical tests, it not exceeded them. Because the system works extremely well, it is a lot of fun and it exudes a fascination that the familiar wired circuits do not have.”

SRAM's Wireless Shifting Will Revolutionize Your Road Bike - Men's Journal

"After spending three months riding it, it’s safe to say that eTap is a truly revolutionary component group that raises the bar for what an electronic drivetrain can be. And it may even redefine the way we shift our bikes."

Bike Company Switches Gears in Road Shifting, Going Wireless | The New York Times

"But SRAM’s new offering, Red eTap, effectively turns bikes into micronetworks that allow shifting that is both wireless and electronic."

 

"Despite wireless advances since then, SRAM quickly discovered that off-the-shelf wireless systems were not up to the job. With Bluetooth, for example, there was too great a time lag. Other systems strained batteries. As a result, SRAM was left to come up with a wireless system of its own."
