When dealing with SRAM, it's wise to assume their design approach is "what's the most exploitative, frustrating way we could do this?"
We've got customers preparing for the Transcontinental Race, London-Edinburgh-London and other ultra-distance events. These riders usually opt for aero extensions; not only is it great to have a variety of hand and body positions if you're riding for literally thousands of miles, small adjustments to your aero profile can make huge differences over long distances.
With Shimano's Di2 electronic gears, you can map any system function to any button. You can duplicate the functions all over the bike: you could have every button on every lever only shifting the front mech into the big ring, if you really wanted to. Just plug in the extra controls, and program them in the app.
SRAM's eTap system requires you to use a "Blipbox" as well as the extra control buttons. The Blipbox overrides the brake lever buttons, so if you want to use the aero extensions to shift gear, you can't use the brake lever shift buttons any more. The alternative is to use their little "Blips", tiny sealed shifters that go under the bar tape. These are £90 a pair, and the batteries are not replaceable. Meaning that when the very cheap CR1632 battery inside runs out, you have to throw away your £90 shifters and buy a new pair. Or, if you're someone who rides thousands of miles, you might not trust their claim of two-year battery life and you have to take a spare pair of shift blips with you along with everything else.
We were only slightly surprised that they haven't got a third option which _does_ unlock the ability to use all the buttons available to you on your bike, but requires a $40/month subscription - but now I've given them this idea, watch this space... 🙄
Plus, that little rubber strap looks like it's doing this: 🤷
