Now without toeclips this would also depend on the weight of the cyclist
Quote from: Soul Surfer on 17/01/2008 11:06:07Now without toeclips this would also depend on the weight of the cyclist I'm not sure that is quite true, why not change gear and pedal faster?It is true that light cyclists are generally better climbers so you would suspect the reverse is true. In the Tour de France, in years gone by, some light cyclists used to collect a bottle filled with the lead before they began a long decent and then threw it away when they reached the bottom. That trick doesn't seeme to be used anymore...probably due to the high price of lead.
Air resistance is generally considered to go up in proportion to the area intercepted which is the square of the linear dimensions of an object whereas mass goes up as the cube of the linear dimensions so all things being equal heavy cyclists should go downhill faster freewheeling but then if the cyclists were pedalling and had high enough gears it could depend on the extra force that the cyclist could put in.
So the skinny but more muscular person could be about the same weight as the fat person, in which case the greater drag on the latter should make the difference.....
i have an addition to this - me and a friend used to go rollerblading down this hill near my house, we both had the same rollerblade (Bauer FX1's incase you're interested) and both used to use pledge on them to keep the friction to a minimum...starting at the top we would just freefall down the hill, now, she was around 11 stone, i was around 6and a half, and every time she would hit the bottom first (unless i cheated and pushed myself forward when she wasnt looking)i know its a little different than a bike but....i wonder if swapping our skates would have made a difference. hers were 2 shoe sizes bigger...who knows.
Interesting. You are approximately the same height?(P.S. what kind of weight unit is "stone"?)
In a practical test while out cycling with my daughter we stopped on a slope of about 25 degrees then released our brakes at the same time and over a distance of about 200 metres without pedaling I was about 20 metres ahead, I am 12 stone my daughter is 9 stone. Although we are not fat I think that proves that weight wins.
