This brings to mind another somewhat related technology advancement I was thinking about the other day. As some of you know, I am a friction shifting, barcon and triple crank rider. My latest bike build project is stalled because I am thinking of putting STIs/brifters on it. I can't get myself to do it. Here's why. I also donate blood/platelets once a month. Type O+ so universal donor. They call every 2 weeks and hound me until I go in and donate. I'm glad to do it since it helps other people live. How does this relate to smart watches, new technology and shifting gears. Well, I'll tell you in the next post.
