Gosh, I'm just a Cat III Forever parking lot racer, not anything like a pro, but I once had a dumbbell intentionally hook me coming around the last corner of a crit, and his fashionably-but-stupidly forward- facing rear skewer handle snagged a spoke in my front wheel. He kept going, even tightening his line (really really really trying to take me down at that point) and dragged me along, front wheel sliding, for say, a quick count to three, before I came off, spoke bent to a new shape, wheel wobbling all over the place, my handlebars pointed well to the right. He got third, I think, I got seventh. Yes, it was "very hard to overcome", but we were sprinting anyhow, you know? Fortunately, my club had some good riders who knew what they were doing, and taught all who would watch, listen, and learn. Not entirely altruistic on their part, of course! <g> Dusty can only wonder at "club rides" that feature crashes. There's at least one famous one here in Austin, going on for years. Haven't been, personally. I'm such a chickenshit, I missed the Death Ride in Houston every time I had the chance (Tuesdays, IMS) to attend during our four years there. > If he barely touches you, of course > you have a chance, but if his momentum carries him 6" across your > wheel you're screwed.

However, as I noted, it's > doubtful anyone has fast enough reflexes. I'd guess that some good percentage of such crashes feature "brakes on" activity. You get a grip, steer into the bike ahead, the one you're overlapped on. Maybe gently, maybe with everything you've got. You get your balance back together with your course of direction, and slide off the wheel. There's no "complication" to it. Beginners especially should not be allowed to overlap wheels, especially when they don't know what "overlap wheels" means in the first place. And you have to show them, not just talk about it. Dang, I keep meaning to post about the kewl front wheel slide my old mentor and riding buddy did a couple of months ago now. We rolled right up to an off-camber, well-polished 90deg corner, leaving a busy street. He followed me instead of the usual other order, and didn't take the good line. We've been through there lots faster... Anyhow, I heard a noise from behind that lasted maybe a little less than a second, by immediate "playback" ("one thousand..." IOW, maybe not quite long enough for the "one") But maybe it was more than one second. A good long Scraaaape! but no bang/ooof. Went back, saw spots on the pavement from AC condensate maybe, or diesel/other fuel spills, but no obviously slick spots, tested with bike tire for "slippery". His front tire was well-scuffed all the way up the label on the slid side, all the way around. Dragged it real good. Rode home more carefully. Tire went to the Hall of Fame. Well, sometimes it's better to just go ahead and crash but I have a story or two for that one, too, as do we all. First thing you gotta teach the newbies, if they'll let you, is not to overlap and what to do when you get caught for it because you let yourself get overlapped even after being told not to when you shouldn't have been overlapped in the first place, especially when it's on another newbie who doesn't know what a "line" is yet. And you have to show them, not just talk about it. --D-y |

Long ago on the Tuesday evening training race (Bustop ride) from Boulder, I was in a train moving forward just before the final sprint. Someone tried to switch abruptly to the wheel I was on and we bounced off each other for a while. Neither of us crashed but we both got knocked out of the sprint. I later found out that his front wheel had ripped an adjustment screw out of my rear derailleur. It was Scott Berryman who was one of the top match sprinters in the country. I'm guessing that he weighed about 220 lbs at the time. We're rolling along together and I'm griping at him about switching over to the wheel like that without looking to see if it's occupied. His answer was that I should ride track and then I wouldn't get so excited when things like that happened. Then he tried to sell me a track bike. I remember thinking that I didn't need to get used to that. Over twenty years later I ran into him on a training ride. He's the same gregarious fellow and we had an interesting conversation. I mentioned the Bustop incident and found he has no recollection at all. Anyway, I think Potter should build a velodrome in his backyard. If you build it they will come. Bret |

If I may: the point being that part of "the fight" is being aware that there are options. Time slows down-- did you see the TV show where they dropped a "volunteer" guy into a net from pretty high up, and he could read faster than "normal" (not falling) from the random numbers being rapidly sequenced on a screen he was holding, while calling out said numbers into a microphone on the way down? True, not a well-controlled experiment, maybe more a demonstration. Moot! We've all experienced the phenomenon. (begging the indulgence, please): Out for a fine, blasting ride in the Midwest cornfield countryside one day, when: "Ooops, we have arrived at speed at a jink in the road, and our line through the ess has turned out to be piled high with river bottom gravel. Ball bearings, as usual. We're sliding and fishtailing through it, trying to stay up, no way to make the corner now, since we can't turn without sliding out. OK, let's stay up here! Damn, this is gonna be close! But look, Paul, who was riding just ahead of me, has ascertained that his momentum will carry him through the gravel (and no, we can't ride in this stuff at all, as usual), and well past what has revealed itself to be a very narrow solid shoulder on the other side of the road, and down into the vertical-wall bar ditch which looks to be some six feet deep, or more. Reluctantly, he acquiesces to a painful low-sider, bike toward the ditch, just in time to avoid a really bad fall into the unknown, since we weren't able to see the near side of the ditch or for that matter, the bottom, which could have had "anything" in it. For myself, not wanting to run over my friend and teacher (who is on the ground now, and grimacing at the impact and the grinding), or, although I do maybe have an open line past Paul, go down into the ditch myself, which looks worse the closer we get to it, I will slap it down real quick right here! Ow, dammit! Crap! I'm OK. Hope I didn't scrape up the bike too bad..." Got up, said some words while picking out gravel, (crap, you just can't see that stuff sometimes), checked out bodies/bikes, no severe damage anywhere, rode back to town and got mostly happy before we got home. Minor road rash, a little bruising, nothing compared to what could have been. One of the best riding lessons ever! Can I get a witness...? --D-y |

If you can keep your balance you can stay up. I'm just saying that their rear wheel can easily push your front wheel aside, but no matter how good you are, you can't simply push someone's rear wheel aside with your front wheel. Some reasons why this is true: * most of their weight is on their rear wheel, and most of your weight is not on your front wheel. * the rear wheel is held firmly in the frame, requiring no strength to hold it straight, where your front wheel is easy to deflect. * if they are turning into you, they have momentum you'll have to overcome. * the front edge of your front wheel is like a lever their rear wheel is pushing. * the rotation of the wheels is going to tend to lift your front wheel, giving you even less traction. If your front skewer catches his spokes, it can lift your front wheel off the pavement. * there's very little time to do the right thing. As soon as his rear wheel pushes your front wheel aside you are falling. I've seen it happen, and been amazed at how fast the trailing rider went down, and that the leading rider didn't even realize what had happened. One thing you can do pro-actively is don't let a gap open in front of you. Stay on someone's wheel. What I've seen happen is someone swings into that gap to try and improve his position, not realizing your wheels are going to touch. Also if some novice is swerving around in the peloton, tell him to knock it off. -Paul |

Or send him to the school of hard knocks and let him find out first hand why swerving around isn't wise ;-) Somebody swerving in from the side, I call gettting taken out, not touching wheels. To me, touching wheels means when I through some inattentiveness let my wheel contact the wheel already in front of me. That need not result in a crash. Joseph |

You're slightly shifting the discussion. The core issue is staying up, not pushing the other rider's rear wheel away. A number of people in this group have fought to prevent their wheel being turned and stayed up. And/or seen it happen. It's very doable, esp. with a little practice, willpower and perhaps a touch of luck. >* there's very little time to do the right thing. As soon as his rear >wheel pushes your front wheel aside you are falling. Not necessarily. Usually, but not necessarily. Practive and willpower can help reduce the likelihood. |

Novices are usually open to constructive criticism. It's much worse with more experienced riders who should know better but for some reason are still wild swervers. Novices who are unpredictable, I will let know in a friendly way that they should clean up their style. Old hands who are unpredictable, I just avoid. Easier said than done. Joseph |

Dumbass, I crashed once from "undercontrolling," or just being "too relaxed." Not as contact with anyone, but by hitting an "invisible asphalt knot" coming out of a corner. I was almost out of the corner and started to stand to respond to a gap that had been allowed to form (not by me). Right at that moment "something" knocked the handlbars out of my hands, for which I had a relaxed hold on. Of course, at that point I could not steer and went into the opposite curb. It sort of hurt. I had to go back over and look closely at the road to see the knotted up section, as there was no crack and not much discoloration. I could not explain the loss of control any other way. It was sort of like an inverted crack would be if your front wheel hit it. I was not looking down, but forward to the riders and the gap at the time of control loss. My dumbass lessons were: 1. wait till being all the way out of the corner before standing/ accelerating 2. if not waiting, keep a strong hold on the handlebars unless the pavement is known to be very good. Or just keep a strong hold for that sort of move in any case. It sucked. |

Usually that means pushing back with your wheel, but being ready to stop doing that the instant there is separation. " Stop trying to bullshit me. There is a science to this. If you can keep your front wheel under your center of gravity you can stay upright. If someone's wheel barely touches yours, sure, you have a chance to do that, but if they nudge your front wheel even an inch to the side your bike will turn sharply and gravity will take over. I'll be happy to demonstrate this at $100 per lesson. Or if you're so confident that "it's very doable" I'll give you odds. How about 4 to 1? If you can stay upright 50% of the time, you can make some real money. -Paul |

You prevent your front wheel from turning, to keep your COG under you and going the same way (approx.) the bike is going. ('nother story): I had a 100lb. female following me, traveling down a road where there was traffic, and suddenly the shoulder ended, with a dropoff-- some kind of deal where they were going to add a lane on the RH side. Whoops, there we were. There was some traffic, with a turnoff coming up. Nowhere else to go, so we hustled along to get off that road. I thought I was over to the left plenty far, when we got hit with a blasting sidewind which moved me over right, and right into her. She knew what to do, and good thing, because I promise I moved her over a lot more than an inch while I fought for control and moved back over to the left. I was 180lbs plus bike, and she moved *me* over back left after I moved her over to the right <g>, fighting to not get crashed off the edge of the slab. I would have felt really bad and really stupid if she'd gotten hurt, as I had some experience at least by that point and she was a beginner. We're back to the "fight for it" thing here, is the object. Hammer hammer hammer. Beginners often don't have that concept. --D-y |

I was thinking about a specific incident at the beginning of a criterium. The guy hadn't affected me...yet. But he was ahead and to my left. I was thinking if he took down someone ahead of me, there could easily be a pileup that might include me. That's the only time I can remember actually yelling at someone in a race. And he did knock it off. -Paul |

Hammer > hammer hammer. Beginners often don't have that concept. --D-y Was this your rear wheel clipping her front wheel or something different? Sure, riders can survive a bump, we see guys leaning on each other in sprints all the time. It's a whole other thing when someone clips your front wheel. If you think otherwise, I've got a lucrative bet for you up there. I guarantee my rear wheel will easily turn your front wheel and you will fall. My bike is effectively a lever, with the long end being the distance between my axles and the short end being the rear half of my rear wheel. That's a hell of a lever. It can easily deflect your front wheel. You can "fight for it" as hard as you want, I'll hardly notice. That's why, as the original poster says, "everyone who does it on the club rides that I go on always does crash." Besides, are you gay or something? Real men always ride behind the woman, to enjoy the view. I like the ones with long braids down their backs, tight lycra shorts... Yeah baby! ;-) -Paul |
