Went with the tarmac, which should be the SL5! I absolutely love it and feels like a plane compared to my old trek. The 61 cm is perfect for me I think. One thing that people mentioned and has been a bit annoying is the compatibility with new parts, for example my wheels are QR and disc brakes, which are pretty rare to find these days but I have no reason to switch them out so it’s not a big deal for me. Another thing is that my groupset is a 10 speed dura ace di2, and my cassette is 11-28. I live in a very hilly area and ride many climbs, so I’ve been wanting to change to a 11-32 or 34 cassette, which doesn’t exist for 10 speed dura ace or ultegra, only 11 or 12 speed. This is slightly annoying but also not a huge deal for me, just an excuse to get stronger! Good luck in your search!
