Last time I rode out of the airport Sat, 21 Nov 2009 04:56:03 GMT John S.

Here's a big one, half a mile from my home. No problem to ride Sat, 21 Nov 2009 04:56:02 GMT John S.

Short wheelbase, small wheels, C of G high and close behind the front wheel -- header bait. Art school craziness pumped up with seductive marketing. John Sat, 21 Nov 2009 04:55:19 GMT John S.

No problem to ride through, using vehicular technique. One mitigating factor though is that Fri, 20 Nov 2009 14:56:52 GMT fred http://sports.groups.yahoo.com/group/chainguard/message/28234 http://sports.groups.yahoo.com/group/chainguard/message/28234 The price is astonishingly high for something that looks like a cross between a design contest entry and an art show entry. Maybe that's why the price is high.

There is a very large mulilane circle that I routinely use and it isn't a big deal.

Here's what Adventure Cycling's Bike Bits had to say about it: YIKES! That's precisely what we might Fri, 20 Nov 2009 12:47:13 GMT avery http://sports.groups.yahoo.com/group/chainguard/message/28231 http://sports.groups.yahoo.com/group/chainguard/message/28231 Hi Jeremy, Back in the mid-1970's I worked on contract in the UK and lived less than a kilometre from the roundabout on the Broadway in Letchworth. I passed Fri, 20 Nov 2009 00:44:41 GMT Peter Rosenfeld http://sports.groups.yahoo.com/group/chainguard/message/28230 http://sports.groups.yahoo.com/group/chainguard/message/28230 I thought they were called "circuses" in London. Seemed like a good name for them. Southern New Jersey, where I live, is also very fond of circles. But they Fri, 20 Nov 2009 00:01:43 GMT John Forester http://sports.groups.yahoo.com/group/chainguard/message/28229 http://sports.groups.yahoo.com/group/chainguard/message/28229 In 1985, Dorris and I cycled through the magic roundabout in Swindon, just coming to it on our way though Swindon during a tour, and the ride was easy as pie.

Maybe so, but if you have been approaching the roundabout at 85 mph, and your car is pretty good at Thu, 19 Nov 2009 12:59:06 GMT Kat Iverson http://sports.groups.yahoo.com/group/chainguard/message/28227 http://sports.groups.yahoo.com/group/chainguard/message/28227 Multi-lane roundabouts do sound dangerous. First, John Schubert sounds right in his description of the difficulty maintaining a curving lane and scanning Thu, 19 Nov 2009 12:58:32 GMT avery http://sports.groups.yahoo.com/group/chainguard/message/28226 http://sports.groups.yahoo.com/group/chainguard/message/28226 First of all let me declare my bias.

For these reasons one should drive quite slowly in a multi-lane.
