SRAM has made its wireless group public:


The site says the stuff will be available in early 2016. We'll see.

Overview of the eTap groupset:

It looks like a winner.

SRAM stuff does nothing for me. In fact, I think SRAM is a degenerate company. However, SRAM did a very good job on this groupset. I like SRAM's approach of putting the batteries on the derailleurs and making the shift signals wireless. Thus, an eTap bike is actually simpler and cleaner than a standard bike:

Imagine combining the eTap bits with something like a LOOK 695:

Imagine that bike with the shift cables and control box gone. The result would be so clean that it would almost look as if several pieces were missing.

I believe the only cables on the SRAM system are on the remote shifters:


Even here SRAM did a nice job with the large diaphragm buttons. These are hidden nicely under the bar tape but are still large enough to find and hit when you're tired or in a hurry:

The Shimano sprint shifter sticks out:

And the climbing shifter is a separate box that's zip-tied to the bar:

The Shimano remotes look like crude prototypes compared to the SRAM remotes.

We'll see how Shimano and Campagnolo react to eTap. I think they have to.

Nice pic of the eTap shifter:

Under the hoods are two ports for the Blips remote shifting buttons one is shown installed in the top port. The screw-on cover plate hides the CR3032 coin cell battery that powers the shifters.

So you can have both climbing and sprint shifters if you so desire. The wires on the Blips are too long for sprint shifters, but I suppose SRAM will release sprint versions of the Blips in the near future.
