Remarkable Dependability.

I've put it through the wringer

Fourteen connections, in a typical set-up, depend on the quality of these wires. It always amazes me when a new build comes to life and the Di2 works exactly as it should, first time, every time. And, I'm impressed how they continue working through crashes and tough conditions. Using the Shimano tool for insertion results in the same "click" every time. The cumulative cost of seven of these wires is significant, but I've only had to pay it once.

Very Good

I've put it through the wringer

Prompt delivery of product as described. Di2 performance is very reliable, most shifts per charge than the competition, crisp and responsive. Hey, there should be certain benefits for all those cables, junction boxes etc etc.
