Shimano's new EP801 firmware update has been developed with Shimano's world-cup winning Yeti / Shimano EP Racing team and proven by Orbea's OOLab and Rotwild Schwalbe Enduro teams. The new features include a higher assist level for Boost Mode, a customizable max speed cutoff progression, and extended overrun. The firmware update is available to all current EP801 owners and will be standard on all bikes built after the firmware release.
