Whats up with bringing off-road cycling into the discussion? Lost track of which thread I was in. Nevertheless it is perfectly fine in my book to try to race the Tour de France with a recumbent. Just try to ride down those Alps roads fast enough to make up for the time lost on the climb. Note: Opinion stated as fact. Here is Tom Sherman sounding like JimmyMac. He should find a different way of saying it. But Mr. Kunich is right. No way you can make up going down what you lose going up. This is as true of small hills as it is of mountain passes. Hey Ed, Jim McNamara picked up the phrase from me, not the other way around. Ever see a race stage that was all climbing and descending - no, I have not either. The assumption that the speed penalty climbing would be equal to speed advantage descending is overly simplistic and unrealistic. You will be stuck forever maintaining various esoteric points concerning ultimate speed on bicycles as can be demonstrated in races. I am not interested in that as you may have surmised by now. I am only interested in the real world of bicycle touring. Then why is Mr. Ed Dolan commenting on a discussion on how recumbents might fare in a professional stage race? The world wonders. When I do a bicycle tour I get rather well acquainted with most all of the recumbent riders and many of the upright riders as well. These are serious, advanced cyclists, but they are not racers. What I see over and over is that recumbents get dropped going up hills and then they really have to step on it to make up for it downhill and on the flats. But they never do catch up because the world is full of hills small and large. I have yet to see a recumbent overtake an upright going up a hill. I can't do it and neither can anyone else. I think your time could be put to better use explaining why it is that recumbents are not able to keep up with uprights over a long distance. Just report what you see with a common sense explanation. Most of us are not into racing nor are we ever going to get top of the line bicycles. Request is based on a false premise. My own observations are that recumbents can stay even with uprights on the flats, but not on hills. This observation is based on 10 years of participating in week long organized bike tours every summer. One summer I did 5 week long tours. Believe you me, I wanted to be as fast as anyone, but hills defeated me and all the other recumbent cyclists. Even small grades will slow you down on a recumbent that you would hardly notice on an upright. That is what you have to explain if you are going to be credible. A aerodynimic recumbent will slow more on a hill than an upright, even if climbing ability of both bicycles is equal, since aerodynamic drag is a smaller portion of overall resistance at lower speeds. I have given up on speed on a recumbent. They are for comfort. If I can average a speed of around 15 mph, that is as good as it is ever going to get for me. Many serious upright cyclists can average around 20 mph. I tried it once and just about killed myself. Try harder next time. -- Tom Sherman - Holstein-Friesland Bovinia “Mary had a little lamb / And when she saw it sicken / She shipped it off to Packingtown / And now it’s labeled chicken.” |

But they are dangerous in a close pack and they are slow up hills. Has TK ever ridden in a close pack of recumbents? I have and short wheelbase recumbents can be less dangerous than uprights. When drafting, hitting the rear wheel of the bicycle in front with one's front wheel can cause a diversion fall, but hitting the tail fairing of the lowracer in front with one's foot [1] is no big deal.

IIRC the main thing he'd found is if you hit the bottom of the hill doing 10 mph more than you'd be doing without the fairing, that was often enough to get you over smaller hills, and a good start on bigger ones, before the weight disadvantages cut in. Indeed. A faired recumbent is great on a series of short rolling hills. -- Tom Sherman - Holstein-Friesland Bovinia “Mary had a little lamb / And when she saw it sicken / She shipped it off to Packingtown / And now it’s labeled chicken.” |

Faired uprights are rare to nonexistent - and for good reason. However, recumbents with fairings can also get blown all over the road in strong winds. In certain situations, it is extremely dangerous to ride a recumbent with a fairing. I've been out on a faired Rotator Pursuit in 40-50 mph winds. It was fun but a lot of work. Cold, too. It would have been much nicer in warm weather. Steeing was OK and there was a bit of lean to make up for sidewinds. YMMV. I have always wanted to try a faired Pursuit. Only rode an un-faired Pursuit once, and its reputation for poor low speed handling seemed greatly exaggerated. -- Tom Sherman - Holstein-Friesland Bovinia “Mary had a little lamb / And when she saw it sicken / She shipped it off to Packingtown / And now it’s labeled chicken.” |

Who cares whether an upright is a few seconds faster than a recumbent or visa versa? I am stating as clearly as I know how that recumbents don't climb hills worth a ****. This make them overall slower on a bike tour with other cyclists who are riding uprights. Is Mr. Sherman a bicycle racer? Don't make me laugh!

For the sake of argument, let us assume that that a particular recumbent is 20% faster on the flats and equal on the climbs to the group members' uprights. If the recumbent rider is just the equal of the group on the flats, that means he is a considerably weaker rider, so it is no wonder he gets dropped on the hills. What is being demonstrated is not the poor climbing ability of the recumbent (which is typically the false conclusion made by the upright riders), but rather its performance advantage on flatter terrain.

At best, it is possible that a recumbent will be only ever so slightly faster than an upright on the flats, but even that is debatable. What is not debatable is how freaking slow they are climbing hills, even small hills. Case closed as far as I am concerned. Obviously Ed Dolan has never ridden a state of the art lowracer, or he would not post such nonsense. The real life Johnny NoCom could set him straight on this matter. There are middle aged guys out there who would get dropped in a Cat 2 race who are riding 4 hour centuries on lowracers WITHOUT any drafting help. -- Tom Sherman - Holstein-Friesland Bovinia “Mary had a little lamb / And when she saw it sicken / She shipped it off to Packingtown / And now it’s labeled chicken.” |
