T1 Shift: USB-C to Shimano Di2 Charger Adapter
€30,00
Tax included.
Your Di2 won't shift. Your charger is at home. Again. We've been there, so we built this. The T1 Shift is a keychain-sized adapter that turns any USB-C cable into a Shimano Di2 charger. Clip it to your keyring or stash it in your saddle bag. Top up at the hotel, the cafe, or right before your race.
