About half will see me and let me by. The other half aren't looking in their mirrors. Those I have to set up by watching how they take corners for a while then taking an alternate line. Often its an outside to inside line as many of them will aim for the apex and then go wide on exit.

I've seen one made in the Netherlands specifically for racing. It's mostly carbon fiber, and has a very 'bare bones' look in order to save weight. It tips the scales at 16 lbs, IIRC. They might not be UCI legal (yet), but they are being raced in Europe against other recumbents.

But even worse is that the rider can't stand on climbs. That's a serious disadvantage.



Light weight is only an advantage for climbing, and since bents are poor at climbing people who want to go fast up hill won't be interested in them.

No argument there. When climbing, there are times when I'd kill to be able to stand up. I can only spin effectively going uphill for so long.

Do you recall the brand by chance? The Netherlands has a nice industry around recumbents and velomobiles. This company appears to make the best - a carbon-fiber velomobile will set you back about $10,000. This one is designed in the NL and built in Canada.



On an even modest slope, it's quite easy to exceed 55.

A group rode across the US two years ago I believe. Here's a brief report.

Oh - they averaged 125 miles a day....

We shouldn't forget Maria Parker's heroic efforts in this years RAAM. Come from behind victory despite losing 24 hours due to her chase vehicle being totaled along with her spare bikes and light weight climbing wheels. Not only did she cacth up to and pass all the women riders she also passed quite a few of the men as well.

Maria and her husband Jim are good people. I believe that one son is in one of the service academies.

Can you imagine how fast they'd be on real bikes?

You mean, fiction shifting, five speeds and no aero brake hoods?


Yes, I can...

It wasn't one of those. I don't recall the name of the manufacturer, but their 'racing' version was very minimalistic two wheeled recumbent, consisting almost entirely of carbon fiber, with no cushioning for rider comfort. There was an optional full fairing available for it. These were being raced across several countries in Europe, starting somewhere in Norway, if I remember right.

Those velodrome bikes don't look any more aerodynamic than the average road bike.

Typically no, they have less drive line drag, no levers, cables, shifters or derailers to catch wind. My average 23 mile TT speed in an Abici Time Machine was 26.5 mph. I was averaging the same with my track bike using a 49/15 gear so I sold the Abici and I never missed it.
