Just got home from the Raven Rock Ramble, an annual fundraising ride (not a race) through the foothills southwest of Raleigh, NC. It draws about 700 cyclists who can choose rides up to 100 miles in length. Maria, Larry, and I did the 100 mile (which was actually 105 miles including the parts...

Are you able to produce more power when your ride on the road, or when you are on the trainer? If you have a power meter, trainer, and heart rate monitor, consider trying to do what I did and share your results on this thread. Here's what I did, and my results. I compared peak power while...

Here is a bullet list, with photos, of some highlights of the event. 1) Cruzbike racers Jason Perez (24H), Kevin Gambill (12H), and (moi) Jim Parker (6H) each set the overall recumbent record in their events. Here are all the new and historical 6-12-24 Hour recumbent results: 2) Big thanks...

...in Borrego Springs, California. The racing begins November 4th. The official records have not been posted. These records are based on posted race results.

While specifically about standard bike racing, much of this article applies to us Cruzbike racers. Maria and I have noticed that when we are passing RWD bents on climbs, we are often switching between our usually laid-back (open) position to a "sitting up" (closed) position. Many standard bike...

I did an interview with a reporter at a large national newspaper today and he asked: "...Specifically, do you know of a man who was experiencing numbness and pain in the perineal area (and perhaps even issues with ED) from traditional cycling and switched to a recumbent and this resolved their...

{What's this doing on the Cruzbike forum? Well, some of the smartest people I know are on this forum, so why not? - Jim Parker, MD} The title of a 2010 documentary movie about cancer treatment, Cut Poison Burn, refers to three types of conventional treatments aimed at fighting cancer. Many...

Sebring, Florida: A record number of Cruzbike racers, seven, turned up to race on February 13-14 at one of the most popular races in the world that allow recumbents to compete. Approximately 1 out of 3 recumbent racers were on a Cruzbike. In the 24-hour non-drafting RAAM qualifier, Ben Tomblin...

This is one of my favorite rides (not a race) every year, sponsored by the Sandhills Cycling Club; 350 riders doing 102 miles with about 5200 ft of climbing along a loop course that covers some of the most beautiful parts of the "sandhills" of North Carolina. It ends with a live band, great...

Your friends here at Cruzbike have been working on many interesting projects. One of them is an aerodynamic carbon fiber tail box designed for the Silvio and Vendetta models. The idea is a sleek and lightweight box that can hold a few essential items, including two standard water bottles or a...

There has been MUCH written about the physics behind climbing on a Cruzbike vs. a fixed-boom recumbent vs. a standard DF bike. However, much of it is buried deep in long threads scattered over the blogiverse. Here is an accessible place where you can view a force vector diagram, or watch a...

My name is Jim, and I'm addicted to RAAM. The Race Across America started yesterday afternoon. This is a photo of Severin Zotter, currently crossing the desert about 20 miles ahead of his competition. Note the mask to keep the dust out of his lungs. Maria Parker, our son Will, and our daughter...

I've been meaning to do this for awhile. With Calvin's Challenge (a 12-hour race in Ohio) coming up in one week, I figured I better get around to it. I used R. Chung's method and his cool app as a poor man's wind tunnel. You need a power meter, a circular course where you don't have to touch...

Spring is climbing season for our cycling friends here in North Carolina. We leave the eastern plains and head to the mountains on at least one long weekend every spring. With that in mind, I just installed a SRAM X7 type 2 rear deraileur with a wide-range cassette on Maria's V20. She just...

On Labor Day Maria and I rode in the annual Tour de Moore, which is about 103 miles with 4400 ft of climbing in hot and humid weather. Here is the bike equipped with four water bottles minutes before the start. I was able to easily reach all of the bottles while moving fast and I was glad I...

After a 20 month battle with brain cancer, she died this morning. Jenny raised five kids with her husband Ray. She gave Maria the inspiration for 3000 Miles to a Cure and her amazing victory in RAAM last year. Jim

Keith and Joy Kling are riding Cruzbikes on a 4265 mile tour going from Oregon to Maine this summer. They are planning to do a lot sight-seeing and cover about 60 miles/day. An interview on their local TV news station is here with some nice video footage of their Silvios and a trailer...

some photos that may help Hi Eric, To remove the drivewheel, First, shift the chain to the smallest cog on the cassette and release the front brake tensioner. Then grab the boom and rear triangle and flip the bike upsidedown. Next, remove the skewer. Standing on the drive side, reach in with...

When Maria and I are eating up the miles on the Vendetta, we're convinced that no other human-powered vehicle could travel our public roads this efficiently. The only thing that used to be missing from our trips was some cargo space. Now we have a practical solution. If you notice in...
