Again, depends on the bent. I ride a high racer which puts me pretty high up, on a level with riders crouched over their bars. I also have a large, bright yellow bag on the back. I get lots more room than the riders around here normally seem to. Then there is the "different" aspect. A bent rider does not blend into the drivers' expected road things so we seem to be noticed. As more folks ride bents that will change, dang it!Aussie Steve said:It's quite obvious that the lower frontal area should translate to better aerodynamics but also must make it a bit less safe in traffic. Much lower rear red light; lower profile means less chance of being spotted by cars...etc
Most seats have lumbar support built in, mine does for sure. The angle of my legs to my body is more open than a DF rider. It took me a while to get used to it - a different neck angle - but I simply started more upright and moved the seat down a notch every 200 miles or so. Never caused me any problem.It just looks unnatural and with the spine seeming to adopt a curvature in the seat, would be no good for my L5/L6 area. The angle between abdomen and quads would be smaller than that on a DF, isn't it?
In addition to increasing aero efficiency, I find that the more open position contributes to better breathing and more power on hills. I brace my shoulder blades to the seat back and power from the core. Awesome. A word of caution, you are in much the same position as an inclined leg press. You should ride perhaps 1,000 miles before really letting this loose. Some people have blown their knees out overdoing this.
Go ask the medical opinions - damned if I know. Wouldn't surprise me, DF's are designed by a committee to fit a rule, not a human.Some medical opinion holds that a cyclists hip flexors are underdeveloped/underworked, presumably because of this angle. So would a "bent" make this worse?
