    Bike Sebring 2018

    This is me at the start of the races, sandwiched between two HPVs. Greg Cantori is to me right. We will pass each other many times during the 100 miles, but he leaves me far behind in the long head-wind section (but not the three stronger Cruzbike racers). Greg was entered in the 12-hour event...

    Bike Sebring 2018

    Cruzbike racers took 1st, 2nd, and 3rd in the 100 mile race. An EARLY Cruzbike breakaway held up. Been doing this event for 8 years and have never seen an early breakaway last very long. Kyle nipped Larry in a photo finish, followed a few seconds later by Jesse. I was way way back in the field...

    Cruzbike KOM/QOM challenge 10-31-17 thru 10-10-18

    Hi Neal - The Cruzbike Ride Retreat is set for 11-14 October which, indeed, conflicts with the recumbent convention. We haven't ever missed a convention, but there's always a first time. The convention moved a week later in the year. Oh well!

    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...

    Has anyone tried a CruzBike "fixie?"

    I'm sure there is someone out there who could ride a Cruzbike fixie backwards, but I've never seen or heard of her. I've ridden a standard fixie, but it's not my cup of tea. I like to coast with my feet quietly resting on the pedals.

    What I did Today to prepare for Sebring 2018

    Maria and I have been doing Trainer Road workouts through Zwift as time has allowed this winter; also earning some virtual new socks and jerseys. We still have a lot to learn about the world of Zwift. We are taking this week off to visit our daughter, son-in-law, and grandson in Jerusalem. We...

    easy testing of aerodynamic drag

    I just discovered that you only get 5 files processed after you sign up with www.fastaerolab.com. After that, you need to buy credits, which are very expensive. So I will keep looking for free alternatives. Golden Cheetah has an aerolab function, but it will not run on my Windows 10 computer...

    easy testing of aerodynamic drag

    That's probably worth a try. Braking or stopping during a test lap will yield a higher Cd*A for that lap unless there is some type of smart adjustment based on the FIT data, which includes elevation. I don't know if that's built into the app, but I suspect it is not. Last year at Borrego the...

    easy testing of aerodynamic drag

    Those are incredible Cd*As, but I believe them. Is the second set with the drop bars vs. stubby bars on the stock V20 frame or the proto?

    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...

    2017 Cruzbike retreat in White Lake, NC

    I had a GREAT time at my first Cruzbike retreat. We did a lot of riding on (mostly) quiet roads, but the best times were just sitting/standing around the beautiful lake-front facility learning about each other and all the bikes and their modifications and gadgets. My favorite ride of the...

    New to the Forum and CruzBikes

    The manufacture of ideal Y-frame MTBs quickly faded after the 1990s. The scarcity of proper donor frames 1) dried up the market for conversion kits, and 2) led some customers do use less-than-ideal donor frames, resulting in bikes that appeared (to us) unsafe to ride. That's why we discontinued...

    Vendetta with fork from S40

    The fork crown-to-axle distance is only about 10 mm longer on the S40 than the V20. So the change in geometry will not be very much. I have swapped the boom and the chainstay between these two models to save $$ on ETap parts, but I have not actually swapped the forks, so I don't know exactly...

    Mid Atlantic Ultra 2017

    I did NOT expect to win this race. I almost decided not to even make the trip because I have been nursing my right knee, which I injured a couple of weeks ago running stadium stairs at the local high school. And then about a week ago I caught my grandson’s cold and have been going through the...

    Team Cruzbike RAAM 2017 - As Seen on Facebook

    It took me a month to catch up on my pre-RAAM life, and to get around to writing a blog about RAAM. Here it is.

    History of Recumbent Teams in Race Across America

    RAAM is a bit like the Super Bowl of Ultracycling. And like the Super Bowl, it's more fun to watch if you know some history (and trivia) of the event. I am posting this to give some basic information that may enhance your appreciation/enjoyment of the 36th annual RAAM. Over 50 teams from a...

    2017 Raven Rock Ramble

    I've learned to prop up the boom when I change a front flat so this separation won't happen, but here is another solution that works if you don't run front disk brakes: Get the front wheel and RD back on and place two medium zip-ties as in the photo below. I put a yellow arrow on the one to put...
