PRO battery holder seat post for Shimano Di2 batteries
Cleaned up! One of the hottest components for ambitious racing drivers are Shimano's Di2 gears. The battery for this is also available in round versions (SM-BTR2 or BT-DN100) for mounting in the seat post. So far, however, you either needed a seat post with a special mount or had to tinker with something. For round seat posts without a special mount, PRO has a simple and protected holder for Di2 batteries in the seat post.
The low weight and easy handling make this holder a useful helper for all "electric" drivers.
