I've cycled fully loaded in the UK and though I wanted to a few times in Wales, I never got off and walked. There are a few very steep, relatively short climbs I remember as being effective at getting the heartrate up, but they only lasted a short time. I also remember some bodacious headwinds. Rosedale chimney (North Yorks moors) was the one I most remember. Can't remember if it's the steepest hill you're allowed to ride up in the UK - but it's certainly close. At a guess, you're not touring with a double chainring and corncob cassette :-) Definitely not a double chainring or corncob casette ( it was a bit of time before casette/freehubs even existed). But, I was no TdF class athlete either. IIRC, my lowest gear was 28 in the front and either 32 or 36 in the rear......Suntour Winner freewheels....and Shimano Biopace chainrings. Never a failure either. (Harlech in Wales has one which is marked at 40%. That's pretty darned steep. It's no entry at the bottom, but since it's a very quiet road you can just give it a go. We couldn't make it in one go - stopped for breath half way up, and that's on the tandem with some pretty low gears). 40%...that's incredible. Climbing on a tandem is more problematic than on a single. Even with my absolute most compatible stoker and the lowest granny gear, there were times when I had to abandon the climb on my tandem....by the way, does the Cyclist Touring Club still exist in the UK? They were invaluable in helping me plan my various tours back in the day. cheers, clive |

Actually in this case we did better than our friend on the single - the long wheelbase helps a huge amount when it gets that steep.

They were invaluable in helping me plan my various tours back in the day. Yup, still going strong, still doing great stuff. They're now called the CTC, to reflect the fact that they do more than just touring these days - they're involved in campaigning etc too, eg their recent success at getting the dreadful draft of the highway code changed. cheers, clive |

Despite what's been said in this thread, motorcycles do it all the time. Different game: you have more speed, so there's more benefit to the rider from comfort of keeping the airstream and accompanying bugs and rain off them, you don't have any weight issues to speak of, and there is no need to make room for pedalling action. But no one bothers to add fairings to uprights, since most people interested enough in such speed tricks are also interested in racing, where fairings are forbidden. The most common partial fairings on motorbikes are for comfort, not speed. i.e., all motor scooters. In IHPVA competition they're not forbidden, so if there was mileage to be had from faired uprights over faired 'bents you'd see a lot more of them than you do. And in the real world outside racing, with no rules and no notion that racing defines what's best, uprights outnumber recumbents more than a thousand to one, even after about a century of recumbent evolution. But given the history that just doesn't prove anything. Windows desktops outnumber Linux desktops by orders of magnitude, so Windows must be miles better, or a de-facto monopoly actually does a lot for market position? But there's no law against starting a no-holds-barred anything-goes bicycle-race organization to find out what's "best". That'll be the IHPVA. Their record sheet is dominated by recumbents. Just a lack of interest. A few armchair enthusiasts can't produce the Tour de France. But they can produce 81 mph undrafted. Pete. Dear Pete, Well, yes, the Varna Diablo II can produce 81 mph undrafted and is the "best" in some sense . . . At the billiard-table flat Battle Mountain highway. With an assisted start and a 5-mile run-up. For 200 meters. With no wind. If we want to go _over_ 81 mph on a bicycle, then the "best" becomes an upright behind a pace car. Here's Marquet in 1937 at 86 mph: http://imageevent.com/dernysportuk/s...=0&w=4&s=0&z=2 *** Neither "best" has shown much practical application for events like the Tour de France. Small groups of faired recumbents do tour, but I don't think that they try to compete against each other. Motor-paced bicycle competition, on the other hand, was quite popular in city-to-city races in Europe. For example, Paris-Roubaix used motor-pacing for the first few years. The 12 km/h drop in average speed in 1901 marks the ban on motor and tandem pacing after the fast but crash-riddled 1900 race: http://www.bikeraceinfo.com/classics...x/prindex.html http://www.bikeraceinfo.com/classics...ix/pr1900.html Here's 1949 motor-pacing in Paris-Bordeaux: http://www.wooljersey.com/gallery/v/...ca_BP.jpg.html Putting the gas tank on the handlebar improves the drafting and allows the pacer to pedal the contraption, but the real advantage is the easily visible advertising for a certain French periodical. Darn that L'Equipe upright de facto monopoly! Once we sue Henri Desgranges, the wicked Bill Gates of the two-wheeled world, we can put everyone on the "best" recumbents! Cheers, Carl Fogel |
