Updating an old bicycle
Most frames made since 2012 have internal routing with cable stops that can be swapped for mechanical or electronic cables. SRAM’s wireless e Tap provides a great retrofit option to older frames, both because you don’t have to deal with a wiring harness and because the batteries are mounted to the derailleurs.
“You install the derailleurs and shifters, pair them, and you’re good to go,” says SRAM road product manager Brad Menna.
Di2-equipped bikes start around ,500—no one’s idea of a bargain—but if you’re set on switching, it may be the smarter choice.
If you go the new bike route, consider whether you want to run disc or rim brakes.

These bikes feature a radical “Y” frame design and even the crank is curved.
This bike was restored from a complete original but the paint scheme is not entirely correct although the colors are…
Plus, the front and rear derailleur batteries are interchangeable.
If one does go dead mid-ride, “you can swap the live battery to the front derailleur, put it in the proper chainring and then put it back on the rear for shifting in back until you get home,” Menna says. Make sure what you’re buying—bike or group—comes with a charger. With separate, smaller batteries for each derailleur, SRAM says a full charge takes just 45 minutes per unit—but there’s only room for one battery at a time, so make sure to leave enough time to power up both.
