The Editor Launches A Frenzied Attack On His Keyboard A Sort Of Hors d’Oeuvre Not much new to report since the last issue, especially as the only event we’ve actually attended has been the European Championships. Missed Hayes because the weather was so horrible - went home to watch the British GP and the World Cup Final instead. Missed Lancaster due to being en route to the Europeans. Missed Kirby and The Lakes due to not having recovered from illnesses picked up while at the Europeans... Anyway, the Europeans were as much fun as usual, and you can’t read all about them in this issue, as there’s insufficient space available. I’ve discovered one thing, though, namely that riding a long distance to an event is not necessarily the best training for racing. Put another way, I didn’t go any faster... Of Boing, Bars And Bottles Following the decision by those eminently sensible chaps at the UCI to ban monocoque frames, further acts of idiocy have crossed my computer screen recently. Firstly, a couple of the US Postal Service team were told prior to this year’s Paris-Roubaix race that their bikes were illegal. Their crime? Having suspension... Next we read that those Cinelli bars with the sort of mini-tri-bar bit in the middle have also been banned. And the crowning glory; the makers of the Camelbak drinking system developed a soi- disant “aero” version for time-triallists. An independent test showed that the difference it made was negligible. However, this wasn’t good enough for the UCI, who have now banned all strap-to-your-back drinking systems, whether “aero” or not, from all road races and time trials. Next week, how pneumatic tyres give an unfair advantage... ...However... ... it seems that the UCI are not the only people around who want to stamp on innovation. A while back, the organisers of one of Sweden’s biggest mass cycle rides decided to ban recumbents, because, appar- ently, they are “dangerous”. In what manner they are “dangerous” was not specified. But, the event takes place on unclosed public roads, 300 km around the one of the largest lakes in Sweden. So the local recumbent enthusiasts decided that they would exercise their right to use the public highway... by riding round the same lake, at the same time, but in the opposite direction! Then there’s the Trondheim - Oslo saga. You may remember Gooner Fehlau’s article describing how Bram Moens set a new record for the event. Sadly, this seems to have had Repercussions: Time to Defend the Future of Recumbents Last year the leading endurance ride in Norway, the Great Trial of Strength, was won by Dutch recumbent rider Bram Moens. This year recumbents were banned. By Ernst Poulsen Only a handful of races are as tough as the Norwegian endurance event - The Great Trial of Strength. The distance is a staggering 540 km across the mountain range - or fjell - between Trondheim and Oslo. And just to make it a serious riders only-event, the time limit is 30 hours. Usually the ride attracts some 3000 cyclists - including the best riders in Norway, many foreigners, - and a handful of recumbent riders. For years none of this constituted a problem, until the Dutch HPV-rider 3 Bram Moens shattered all records, and won the 1997 event with a full one hours and 45 minutes in front of number two. But instead of celebrating Bram Moens as a winner, the organizers gave the first prize of $2000 to another rider - and to top it all off recumbents were banned in the 1998 event. “They simply ignored me, when I arrived”, explains Bram Moens, who later went back to Norway and used part of his vacation to speak to the organizers. This didn’t change the decision. Örn Ulf Pedersen from the event organization, admits that HPV’s never constituted a problem - earlier on. They were only a rarity. Bram Moens’ fast ride changed this: “This isn’t a competition - it’s an endurance event1", explains Örn Ulf Pedersen, who admits that the 1997 event did have a special “record group” which competed for prizes. Recumbents were allowed to sign up for this group, and the rules - which state that helmets must be worn, and that Triathlon handlebars are not allowed, did not state anything about recumbents. Apparently the organizers underestimated the speed of the recumbents. Only one or two minutes before the start, Bram Moens and the other recumbents were taken out of the record group, and were told to start 10 minutes later. This soon became a problem, when several of the recumbent riders had to overtake the entire record group soon after the start. At the finish line in Oslo, two of the recumbent riders finished way ahead of the rest of the pack. But the fact that recumbent suddenly proved to be much faster than the record group, also constitutued a problem. “The cost of police patrolling is also of importance. We pay 180000 Nkroner (20000 Euro), and it gets more expensive when some of the riders arrive that early, as the police have to follow them too”, Örn Ulf Pedersen explains. The organizers did get an early warning that recumbents would be faster than all other riders. Bram Moens participated in the 1991 event and was ahead of everyone else - until 50 km from the finish line, when a serious stomach ache took him out of the race. But according to Örn Ulf Pedersen, the organizers never realized this: “We only see the final results”. Despite the dispute this year - the door may not be entirely closed to recumbents in the future. “As we see it, recumbents may be back next year. We would of course like to see as many participants as possible”, explains Örn Ulf Pedersen, who hopes to meet with HPV-riders later this year. A Potentially Useful Gadget While golfing2 the ‘net recently, I came across a product called the “Shockster”. This is a device cunningly wrought to convert your boring old hardtail mountain bike into one with rear suspension. It attaches to your existing rear dropouts and cantilever bosses, and gives you of the order of 3.5” of suspension via a coil spring / oil damper arrangement. Ed Gin in Chicago has already fitted one to his Lightning SWB recumbent bike, and reports himself well-pleased with the result. As well as the canti bosses, you need some sort of rear triangle, so all you lot fantasising about putting one on your Kingcycle can stop right now. Ed has a detailed report on the fitting and performance of the thing on his Web page, at http:// www.mcs.net/~gkpsol/shockster.html, while the manufacturer’s site is at http://www.shockster.com/. I don’t know if it’s available in this country yet, but I’m sure that if you contact the makers, at [email protected], or BikeControl Inc, 9640 SW Sunshine Ct., Suite #700, Beaverton, OR 97005, USA, they’d be delighted to sell you one.
