On chrome-moly road bike with a CF fork (bike weighs about 22#) I averaged 15.9 mph last weekend on a 43-mile organized ride through hilly territory in lakes country. Lots of 3-5% grade rolling hills and a couple short 8+% grades. Virtually no wind. My last club ride was just short of 25 miles on dead flat ground with light breeze and I averaged 15.7 mph which included a few miles through city traffic.
