First time riding in the Marin Headlands following a route by the bikeseyeview guys here: https://www.bikeseyeview.com/main/mill-valley-headlands-loop
Highly recommend as it's a great route with a steady climb to start then nice wide downhill and finishing up with a tour of Golden Gate and Sausalito.
Yeah I went a bit off the deep end with the oil slick trend a while back. It's the Supacaz Prizmatik Super Oil Slick bar tape. It's actually pretty thick and decently comfortable but very stiff and was a pain to wrap. Especially around tighter bends it tends to bunch up. It's grippy and definitely noticable though.
