Interesting. I"m definitely in the Clyde club -- although maybe not by the end of summer.
My avg speed is already increasing. Today on my 27 mile round trip commute my avg was just a bit over 16 mph. I was actually averaging about 17.2 until the last 1.5 miles where I run into a hill that starts gradually and gets steeper -- and I lost a whole avg mph on that hill -- pretty embarassing.
I was also delayed when my buddy who lives about 1/2 way up saw me coming and came walking out with an ice cold beer. How could I pass that up? : )
Besides that hill, the rest of my commute is some small rollers and probably 70% that is mostly flat. Still consistently hitting 42 and change on the way down the first hill -- would like to get 45, just for the heck of it.
My goal is to put 1,000 miles on this new bike this summer. Add that to the MTB and the fun riding with the kids (Sat or Sun morning rides wehre we go about 8 or 10 miles in about...oh...three hours! Stop at the creek, at the park, at Grandma's house, etc -- but they love it).
I love this bike...I do have to investigate a creaky crank arm this weekend though...non-drive side.
