First impression after 3 days of intense riding: WOW. I'm coming off a heavy commuter bike and the 2021 Roubaix Comp is unbelievably fast and smooth. Speeds that were previously a struggle are maintained with ease on the Roubaix. As an example, I could manage B17 rides, 17 mph on flat roads, on my old bike. Today, I finished an A20 ride and I could maintain the 20 mph even while riding at the front. I can't wait to see what this bike can do as I get in shape this summer! The disc brakes are strong and progressive. The bike turns on rails without being twitchy or unstable. When hitting downhill speeds of 45 mph the Roubaix was stable and pedaling hard at the bottom of the hill in the drops was confidence inspiring. My worries about steep hills were immediately put to rest at the first 13.5% grade miles from the bike shop. This would have been a disaster on my old bike. I could power through in the lowest gear on the Roubaix. Although straining, I was still smiling! While I was originally looking for a Tarmac, they were not available during the COVID inventory shortages, I am very happy that I ended up on the Roubaix. The bike prevents the little bumps and vibrations from translating to me. I test road other bikes at the various bike shops and the Roubaix was noticeably smoother. When I test rode a bike with a Future Shock 1.5, the first impression was the front tire was flat. I was delighted that my 2021 Roubaix front end felt like a normal bike. Just make sure you have the bike shop install the Future Shock spring, I choose medium but can swap them out later if necessary. I hope this review helps someone decide on their bike.
