TL-EW300 E-tube Di2 plug tool, 3.45 mm, Black

Bought this for my new Di2 which is the upgraded for the 12 speed. The older one (11speed version) does not fit now because the wires are much smaller and will damage far easier so this tool is a must have when transporting your bike. Used when boxing bike ready for airplane. Used when transporting with other bikes and stacked tightly together. If the lever is touching during transport then it could damage the derailleur. 5 other people asked me for help when in Majorca this year on a transfer to start a big ride.Fits easily into my bike bag so always have it with me. Would highly recommend and well worth the money.

It work as intended

Just what you need for Di2 cables

nothing fancy, works well and is nice to have

tool works well for easily removing and installing new Di2 cables

Works

This is used to connect and disconnect wires for a Di2 12 speed. The wireless shifter generation. Do you need it? Maybe. I got it to update my shifters. The wires can be pulled out by hand, without the tool. Should you use it, probably. For me it was easier not to. I just used a long wire and connected it from the battery to the controls to do my update. I never used the tool.
