will you be getting them only later or is it a soon to come thing? You'll have to see how you find the hood shape, I was used to the fatter shape of my shimano tiagra sti's, so the narrower shape was so so, but honestly, over time they are fine, and I really never think about their shape anymore.
Not sure if I'll be able to help if you have any installation questions, but do ask if you have any.
ahh! Worthwhile consideration! I’m waiting on them to be machined then sent to me. However, the same Tektro brakes and same Microshift barend shifters came stock on the bike. I love the more narrow hood of the Tektro lever.
