... In article , Where you do see bent riders is out on long, flat rides. Which is great. That's where adding a couple pounds of fairing looks like a great compromise. But the Earth is not flat, and when the ground turns upwards, bents become tiresome. Especially when you think about the headwinds typical in flat areas, faired bents look good, especially if there are no structures chopping up the inevitable crosswinds, but how many of us ride in those conditions? |

I would have to put 2 years into uphilling to really know. I'd be game to do though! But I live in Michigan instead of my old Colorado. Final two bits: most riding is done in moderate terrain.

But sooner or later you have to go uphill and there's no way to beat gravity. Best way to decide is let them in races. They were originally banned because they were faster than uprights. If they are faster people will switch. Slower and they go the way of Biopace chainrings. Jim |

The best way is to do as with the MTB, that the UCI ignored until NORBA had more members than the UCI, in the USA and elsewhere. If they were allowed in races, a flat TT would require that every rider also have a special TT recumbent. HPVA has shown that for flat record attempts, recumbents are superior. We don need no steenkin UCI to discover the strengths of recumbents. Jobst Brandt |

There are a couple 30lb fullfair carbon lowracers out there these days that I suspect would do great in very rolling terrain. My 60lb fullfair lowracer does great in modest rolling terrain---I mean 30-40mph average, what lovely momentum it has. Bring such a bike down to 30 lbs (as several do) and you really can increase the hilliness I suspect. But for steep climbing a 20 lb unfaired bent would be good to test for a couple years in each of a variety of geometry configs. Who knows. I just haven't seen enough data yet. I do recall some folks mentioning the need for big heatsinks for disk brakes for faired bikes in the mts. (Is that correct? Would disks need big heatsinks for controlling 80mph descending?) Best way to decide is let them in races. Maybe it's more like Jobst said, with a twist. You don't even really have to have their group get huge for them to be considered impt. Is there a huge tandem racing association? Yet there's a chance bents could be quite a bit bigger of a sector than tandeming. Without a big race group for them. They could just get bigger and bigger in terms of clubs and centuries. Probably quite a few innovations have caught on and spread in these places without them having races built around them. But of course the race angle could grow, too. (Tandem racing has grown some it seems, but tandem club riding has probably grown lots more.) -- Jeff Potter **** *Out Your Backdoor * http://www.outyourbackdoor.com for modern folkways and culture revival... ...offering "small world" views on bikes, bows, books, movies... ...new books featuring: XC ski culture, a Gulf Coast thriller folding bicycles ... with radical novels coming up! ...original downloadable music ... and articles galore! plus national "Off the Beaten Path" travel forums!

Because of the HPV community's attachment to fairings of various sorts, I have been unable to determine that unfaired 'bents really are any faster than normal bikes. I started with the assumption that 'bents must be faster, but their boosters' refusal to compare apples to apples got me wondering whether that was really the case. Now I just don't know, not having seen any good numbers for known unfaired bents in TT events. Well, the death-knell for recumbents in road racing as sounded by the UCI which thought the unfaired Velocar recumbent had a unfair advantage over riders on conventional bikes. Of course, that was decades ago and there was no quantification or actual analysis done. It would be possible to build a 'bent that would be legal in USCF races, both mass-start and TT. It would be an interesting experiment. |

IHPVA seems less interested in nonfaired records. In places like Lelystad, the vast majority competes with lowracers, though maybe most of those folks have a tailbox. A tailbox doesn't have very many practical disadvantages though, and it could make a useful cargo space...
