Nope. Drafting AKA Tailgating is a crime and punishable by a fine. There is a significant increase in risk of harmful injury, property damage, and expensive medical bills when travelling too close, too fast, and on wet roads. I am not an actuary but I imagine that as the size of the peloton increases so does the risk of a larger crash for the man in the middle or the back of the pack.

Drafting behind even larger vehicles such as a bus or a semi-trailer can not only reduce your drag to pretty much zero but also (if you’re willing to get close enough) provide you with thrust due to the vortices that are shedding behind in the low-pressure zone creating a suction effect. Just ask Evandro Portela… he managed to draft a semi-trailer on a freeway at 124km/h. Look up “bike draft 124km/h”… just remember, don’t blame me if you try it yourself and end up in a hospital.

informative video as always is to be expected from Ollie. I remember once while I was touring with a front and rear panniers, about as aerodynamic as Connor Dunne on a brick bike, I was flying down a long hill fully loaded, probably reached about 65kmh, which is a lot with panniers on. I am managing the bike and staying upright and the wind noise is pretty much blocking everything else. I notice by the side of me a small car passing me and as soon as he has his nose just in front of my wheel it was almost like cycling in a vacuum for a hair of a split of a second and then I felt a severe block of wind resistance coming in from the opposite side where the first car passed me. I almost lost control of my bike and nearly swerved into the next car passing me. A real life education in drafting and cycling into a wall of air at speed.

Solo I really like traffic assisted aero. I can get a 5mph boost from a large truck on a large shouldered highway. At a stoplight the truck gathers a large entourage behind it prolonging the effect especially when heavily laden. A crosswind magnifies the effect. Vary the position on the shoulder toward the edge for traffic going the other way. Never push your luck in the traffic area though. Connor is much like a tandem team. He has The power of 2 riders but not twice the frontal area. Reynolds number is also lower than average ,similar to a ship with a longer waterline. Finally the weight and aero drag of the bike are minuscule proportionally to a smaller rider. He must have been a great domestique!
@gaborozorai37143 жыл бұрын
When the peloton fills a wide road from edge to edge, doing 60 kph in the run-up to a sprint finish, they must be pushing a lot of air. So what is the effect on those riding at the front? I've always wondered how the same lead-out riders can keep those speeds up for several minutes, so it must be significant.

Hey Ollie, need your help! I recently purchased a 2020 Scott Addict RC30 road bike which I love. Except for one part: the disc brake rubbing. When I'm out of my saddle putting the power down and rocking my bike side to side, on a sprint or climb, there's an annoying rub that has become louder and louder. It even happens when I'm hit by a big gust of crosswind. It seems to come from one side, but I'm not sure. I believe this is due to the fork flexing and thus the pads coming in contact with the rotor due to the little amounts of tolerance. I have flat-mount Ultegra hydraulic disc brakes. I've been to the local mechanic twice to no avail. The rotor is straight, the calliper is centered, the rotor is torqued correctly to the hub and the thru axle is tightened enough. My last thought is that maybe the pads need to be removed and the pistons cleaned with some degreaser. Is it possible the pistons aren't retracting enough? Please help, this is the last thing stopping me from fully enjoying my new ride!
