Installation: is wireless always better?

Let’s get practical. If you have ever tried to thread Di2 cables through a modern carbon frame, you know it can feel like performing surgery with oven mitts. Shimano Di2, even in its latest 12-speed iterations, is still “semi-wired”—meaning you’ll need to connect the derailleurs and battery with wires, though the shifters can be wireless. SRAM eTap AXS, on the other hand, is gloriously, blissfully, fully wireless. No cables. No fishing. Just bolt on the derailleurs, pair them, and you’re ready to ride.

But there’s a twist. Some riders actually prefer the security of wires, arguing that it reduces the risk of wireless interference or dropped connections. And for those who love to tinker, the process of installing Di2 can be oddly satisfying—like solving a puzzle that only you can see.

Battery life: how far can you really go?

This is where the debate gets heated. Shimano Di2’s central battery can last between 1000 and 1600 kilometers on a single charge, depending on your shifting habits and conditions. That’s enough for most riders to forget where they put their charger. SRAM eTap AXS uses individual batteries for each derailleur, with a typical runtime of about 60 hours per battery. For most, that’s a couple of weeks of riding, but it does mean you’ll need to keep spares on hand—especially if you’re heading out for a multi-day adventure.
