The Shimano SM-BTC1 Battery Case is designed to securely mount the SM-BTR2 battery externally on a bicycle's water bottle bosses. This innovative design not only provides a sturdy housing for the battery but also acts as a Junction B, facilitating seamless connectivity between the shifters, battery, and derailleur.
Featuring six E-Tube wiring ports and a cable organizer, the SM-BTC1 allows for easy system expansion, making it ideal for cyclists looking to enhance their bike's electronic shifting capabilities.
