    Another V20/V20c rear rack option: the S40 rear rack

    The Vendetta is not just for racing. For those who find the V20/V20c their go-to bike for commuting or long leisurely trips, there is naturally an interest in carrying stuff on a rear rack with or without panniers. There is a good thread about this here. Another option is to use the S40 rear...

    SOLD: Beloved Q45 for sale, Space Coast of Florida

    This has been my go-to bike for riding around town and to the beach. The boss says I need to be riding the latest model, so out with the old, in with the new. I think this is model year 2019, which uses QR skewers, not through-axles. Gearing is 11-speed 11-40 cassette with a 38T chainring. SRAM...

    Welcome to the new spot to talk about ZWIFT

    Zwift has become a very important part of many Cruzbike owners winter training, especially in this time of a pandemic. Riding a bike on an indoor trainer is notoriously dull. Zwift, with its colorful worlds and avatars, makes riding indoors really fun. It can also provide a very satisfying...

    Too big or too small for Cruzbike? Check the Chart. Take the Poll.

    I recently wrote a blog about which potential Cruzbike owners should definitely find a test ride, and who may go straight to owning a Cruzbike without much worry that the bike won't be a good fit. I created these charts based on my experience with customers and the bikes. I'd like to know how...

    Memorial to Würzburg Bombing Victims

    On a bicycling vacation one does not expect to confront the horrors of World War II. Maria has been blogging elsewhere about our trip to Europe with our Cruzbike Q45s. This post is about a moving experience not directly related to Cruzbike. Bicycling all day through Bavaria and strolling the...

    Keeping an eye on the TransAm race

    Dave Lewis is in a lightweight CF velomobile about 1200 miles into the race and sitting in 10th place. And... Kansas is coming. This is pretty amazing considering the hills he just climbed. http://trackleaders.com/transam18f.php While he's not riding a Cruzbike, velomobiles are a recumbent...

    Raven Rock Ramble, North Carolina

    Here are a couple of photos taken after the event. L>R : Jim, Doug, and Larry. Hundreds of riders picked various routes. This trio did the 100-mile. Larry would have beat me by a lot this year, but he took a wrong turn (actually a U-turn) AND got a flat. We still finished together. My average...

    Bike Sebring 2018

    It's been a long cold winter! Almost all of my riding has been in the garage. But Maria and I will be packing up the bikes and heading to Sebring, FL in 2.5 weeks. Fast time or slow time, it's always a great time for a Cruzbike get-together at a recumbent-friendly race in sunny Florida. We hope...

    easy testing of aerodynamic drag

    I recently tested fastaerolab.com which has apparently replaced the online tool by R. Chung that used to be found at cyclingpowerlab.com for using your power meter and a quiet road loop to do Cd*A testing. Using the old system was quite cumbersome, requiring the use of a DOS shell and...

    History of Recumbent Teams in Race Across America
