You are right, everyone does these things, both in their cars and on their bikes. The point is safety and driving according to the conditions that exist at the time - if I roll-through, it is safely - if there is any traffic, I stop Yes, I believe in PR stops too. Cars at 4-ways often wave me thru. (how many actually bring their cars to a complete stop at a 4-way?). My view is there is more risk coming to a complete stop on a bike because I have to keep my balance. As for sidewalks, very rarely I take them, but occasionally I will because it is safer - for example - the Laurier St bridge. I take the middle of the lane.

Re: [obc] advice on new rear wheel
Roger Guillemette ([EMAIL PROTECTED]) writes: Greg's point is well taken. The breakage of spokes on new rear wheels can be due to poor construction, new spokes loosening up, or weight extremes (such as carrying heavily laden panniers with groceries on or touring gear). Judging from your description Derek, it may be just loosening of new spokes which aren't being attended to. This problem increases with wider gear blocks (i.e. 9 or 10 cogs on back versus 6 or 7 cogs). This may or may not be a contributing factor. The problem is the ratio of the tensions in the non-drive side spokes compared to the drive side spokes, which is in the opposite proportion to the angle of the spokes from the vertical (to be really fussy, it's actually WRT to the sine of the angle, but there's not much difference at the angles we are discussing). As the gear manufacturers gave us more cogs, the hub manufacturers increased the width of the hubs - 120 mm for 5 speed, 126 mm 6 speed, 130 mm 7 speed, and I think 135 mm for 8 9. These figures are for road wheels - mountain bike wheels have frequently been one increment wider. This is one way that the manufacturers have sought to reduce the imbalance in spoke tensions. In addition, on many recent hubs the non-drive side flange is considerably further from the dropout than used to be the case with the traditional 5 speed hub. The critical factor is the ratio of the distances of the two flanges from the centreline of the hub. So for any given number of cogs and width of hub, the hub with the non-drive side flange furthest from the dropout would be the one with the least differential tensions between the spokes on the two sides. As always there are other negative effects that follow from this SNIP -- Peter James Ottawa, Ontario -- To unsubscribe, send a blank message to [EMAIL PROTECTED] Club Office: [EMAIL PROTECTED], (613) 230-1064 Web/mailing list: [EMAIL PROTECTED]http://www.cyberus.ca/~obcweb Newsletter: [EMAIL PROTECTED] http://www.cyberus.ca/~obcweb/Newsletter ==^ EASY UNSUBSCRIBE click here: http://topica.com/u/?aVxiDo.a2i8p1 Or send an email To: [EMAIL PROTECTED] This email was sent to: archive@jab.org T O P I C A -- Register now to manage your mail! http://www.topica.com/partner/tag02/register ==^
Re: Road Safety Training was [obc] Sidewalk Cycling
Yes, yes, yes. I agree with Peter's observations/conclusions - and I really wonder how many people with marginal traffic sense luck out and pass motor-driving tests... Celia Peter James wrote: But in today's society, children rarely interact with traffic. At home they are bundled into SUV's, unable to see the traffic ahead because of the headrests on the front seats. Very little opportunity here to learn how the traffic works. At the mall they are sheperded from the parking stall to the entrance, with no concept of roads, intersections, or who has right of way. When they go to school they wait at the side of the road for the school bus - and if it's on the other side of the road all the traffic magically stops so that they can cross the road. No chance to learn to cross the road safely. Then at school the bus probably lets them out in a restricted-access area. Again, no interaction and no learning. Finally, arriving back at home they again cross the road, this time from in front of a parked vehicle - which in any other circumstances is the most dangerous place to cross, being hidden from traffic approaching from the rear. I have taught children (other than my own) and their lack of traffic sense was, in short, terrifying. At first I wondered if their parents were blindfolding them in their vehicles! My younger son, 8 at the time, came to one of the classes, and he too noticed this. It was from those experiences that I developed the train of thought I've summarized above. It's an indictment of society that we've taught childern to be afraid of traffic, instead of understanding the rules and how they work (or don't). A simple example of this is crossing the road. I'm convinced that most children now don't learn how to cross the road - because it's a skill related to walking to school and to shopping in a neighbourhood street, not in a mall. But even so, it is North American practice to force pedestrians to cross at an intersection - where traffic is coming from as many as four different directions, and visibility is often poor. Now granted sometimes you have to cross at a intersection, but often you don't. In the UK we were discouraged from crossing at intersections, and encouraged to cross mid-block. Here traffic only comes from two directions, visibility is better, and drivers aren't distracted by the other challenges asssociated with negotiating an intersection. -- To unsubscribe, send a blank message to [EMAIL PROTECTED] Club Office: [EMAIL PROTECTED], (613) 230-1064 Web/mailing list: [EMAIL PROTECTED]http://www.cyberus.ca/~obcweb Newsletter: [EMAIL PROTECTED] http://www.cyberus.ca/~obcweb/Newsletter ==^ EASY UNSUBSCRIBE click here: http://topica.com/u/?aVxiDo.a2i8p1 Or send an email To: [EMAIL PROTECTED] This email was sent to: archive@jab.org T O P I C A -- Register now to manage your mail! http://www.topica.com/partner/tag02/register ==^
Re: [obc] Results-handicapping
I like the idea of always making an extra age/gender handicap page available for each TT - but I'd want the handicapping method to be better justified than what we currently have ( http://www.cyberus.ca/~obcweb/Racing/TimeTrials/Results/tt/2001/age-gender-hcap.txt ). I know of a British age-standards table (don't know what data it was based on) for men (I think it was for 25 mile TT's), but I haven't found any standards table for women. Has anyone else? So far as a separate handicap event, I definitely lean towards personal handicaps. We already award medals on the basis of performance for the CCA age/gender categories (and could still award the special age/gender handicap trophies on the basis of best time from the age/gender handicap pages constructed every week) , so why not do something else with a handicap event? I always felt that the idea of a handicap event was to try to place everyone on an equal playing field so that everyone has a good shot at the top/bottom or any other spot. The idea is that this provides more fun and more competition for all. This can push all - from fastest to slowest - to PB's.
