Meh. While as (nearly) always Shimano appear to have executed it very well, it really leaves me cold.
I don't doubt the touted benefits of electronic shifting and for those who really want it, this is great that Shimano are offering this at a lower price point. However as it seems with many aspects of cycling I can't help but think the electronic shifting offers disproportionate marginal gains in terms of functionality relative to the downsides that come with it.
I'm very pleased to see that they've retained R7000 as I absolutely love this groupset on my bike and I guess killing it would leave a gaping hole between 10-sp mechanical Tiagra and 12-sp electronic 105. I guess it's inevitable the Tiagra will eventually become 11sp as the endless march towards more gears trickles down the heirachy, and that there will probably be a move towards a 12 speed mechanical replacement for R7000 in time - although I'd be in no hurry to adopt that either.
Long live R7000 tbh!
