PRECISION on Dura-Ace

PRECISION Firmware Upgrade 1.5.0 Now Available

 

Why upgrade?

Keeping PRECISION’s firmware current ensures that its data is as precise as possible. For example… a few users have reported power spikes at the bottom of a descent. This update will reduce the likelihood of this occurrence.

How to upgrade?

Same as previous upgrades:  With the latest 4iiii app, follow instructions in the PRECISION Configuration screen.
