These are my 2022 Strava bike stats on my Eddy Merckx Professional. It seems I’m going downhill compared to my 2021 Strava stats and my 2020 Strava stats. It’s definitely connected to age and maybe fewer days of good biking weather.

These are my 2022 Strava bike stats on my Eddy Merckx Professional. It seems I’m going downhill compared to my 2021 Strava stats and my 2020 Strava stats. It’s definitely connected to age and maybe fewer days of good biking weather.
In February of 2013, I switched to a Specialized Roubaix Armadillo Elite for the rear tire of my De Rosa Professional bike.
Last month, I finished building up my Eddy Merckx Professional. After some research, I decided to use Continental Grand Prix 4000S tires on that bike. Because the Merckx is “new,” I’ve been riding it on sunny days. When the roads are wet, I’ve been riding my De Rosa Professional. There was a significant difference in the feel of the bikes. Except for the Merckx being 1 cm larger in the seat tube and the corresponding geometry changes, the bikes are similar, both probably made by De Rosa with the same brake bridge and bottom bracket shell.
I attributed the difference to the tires. I can’t complain about punctures with the Specialized Roubaix Armadillo Elite – I don’t think I got one in 5800 miles. As is evident in the photograph, it did wear into a large, squared off, contact patch, 9/16″ (14mm) wide. I switched the rear tire on the De Rosa to a Continental Grand Prix 4000S and the De Rosa no longer feels like a truck.
I took a bike ride with a couple of thousand bicyclists and pedestrians on September 3, 2013, on the just opened San Francisco – Oakland Bay Bridge’s new East Span.
The 15.5-foot wide bicycle/pedestrian path on the new Bay Bridge almost goes to Yerba Buena Island, then ends. A section of the old bridge will have to be demolished before the path reaches Yerba Buena Island and Treasure Island.
There is access to the path from the Bay Trail that begins in Emeryville and from Oakland on Maritime Street and the aptly named Burma Road.
