Just an update on my Sirrus 6.0. I had problem with the seatpost lowering as I rid over my normal 15 mile route the first two times I rode it so I watched a few youtube videos to find out that the little rubber washer/rubber band commonly breaks very easily was the most likely culprit and sure enough I found out mine had broke. I replaced it with a small rubber band and torqued it back to spec and didn't have the issue on today's ride.

Today the wind was negligible and I averaged a moving speed of 14.5 MPH (overall speed with my 2 water breaks was 14 MPH). The best I ever did on my old heavy 20 year old Trek was 12.7 moving speed with the wind at my back but my average had been 12.1 MPH over 10 rides with my old bike. There is an elevation change of 775 feet up/down over the 15 mile ride and it was a bit warm 84 degrees today with humidity between 33% when I started and 44% when I ended. My first ride with the new bike was 14MPH and 2nd was only 12.7 MPH (but the wind was 22-30MPH for half of the ride) both with the seatpost slipping take me out of my optimal position.

So far I am extremely happy with the bike and the way it performs!
