Oh please God, not this again…
Electronic is vastly superior. Cabling routing becomes irrelevant, you can route the whole thing internally, it never needs adjusting, never suffers from sticky or rusty cables and it’s quicker to shift. You can also have subsidiary shifter buttons for use when sprinting or climbing to avoid having to reach to the hoods.
And all this crap about “what if the battery dies?” The battery lasts MONTHS. If it dies mid ride, you’ll have been ignoring the warning light for 500 miles in which case, you’re too stupid to be allowed out unsupervised.
Edit for TJ: it copes fine with water, mud and salt. Pros have been using it in CX races and in the TdF and numerous other races in shit conditions. Works fine, better than cables.
