Shimano EW-RS910 2-Port Internal Di2 Junction Box EXCELLENT USED
Excellent functional condition taken off of parts bikes. I am selling four sets of these, so there may be a slight variance from the pictured unit. All are functional and come with necessary accessories.

Pulled off one of my bikes as I upgraded to 12 speed. Works flawlessly and is ready to be put back into service. Feel free to shoot any questions my way
