T1 Shift: USB C to Shimano Di2 charger adapter

That moment when your Di2 won’t shift. And you realize your charger is at home... again.

Yeah, we’ve been there. That’s why we built this.

Meet the T1 Shift, a keychain-sized adapter that turns any USB-C cable into your Shimano 12-speed Di2 charger. It's designed for the modern rider who’s tired of carrying fragile, proprietary gear, and just wants to ride.

Whether you’re prepping your bike before travel, topping up at the hotel, or giving your derailleur a lifeline at the café stop, this is the tiny tool that saves your ride.

Just clip it to your keyring or stash it in your saddle bag. It’s ultra-light, ultra-reliable, and built to handle sweat, rain, and the real world.
