Dropping it off a cliff is the cheapest, but there are higher end alternatives. Surprised you didn't mention bearings. hambini kind of dismissed ceramic, but for real cheap you can replace two rubber seals with non contact labyrinth seals. It would be nice to have some data on it though. lube. You've covered wax, but different drip lubes have a couple of watts of difference in tests. Bigger tires and lower pressure on real roads. A more forward seat position allows more power. Aero bars work too obviously if suitable. As mentioned above, buying clothes a size smaller costs nothing.

@ GCN Tech During the 80's in NSW Australia when I used to race 40km in 42mins (57.14 km/hr avg) in A Grade road races & 1km in 52 seconds (69.23 km/hr avg) in A Grade cement velodrome track races which I'm not sure if current races are much faster but who knows. My road bike was a Reynold's 531 frame that I asked the shop to tell the builder to make it so that the front tire would sit around 1cm away from the frame & to use forks that you would use on a track bike that were extremely responsive instead of the larger raked forks of road bikes. I had one of the first Aero Reynolds 731 frames for my track bike, both bikes were laced with 32 spokes, tubular rims, stick on singles tires brand name Clement 12's for road, Clement 9's for track. Both bikes I could lift with my pinky finger, very light, 44T-54T to 21T-11T Durrace AX gearing for the road, I think I rode a 93 inch gear for the track bike with Campag hubs. But none of these things were the reason for high speed in races & I think most people out there have lost this knowledge so I will pass along some tricks that no one really has tried much. When you build up Muscle Mass or Bulk up then your muscles are not as flexible as you need them for High Cadence so what everyone does is have a balance, well this is wrong to do, you need to bulk up but do Martial Arts stretching exercises which allow you to also do a standing splits with your bulky legs. You also need to trick your mind also because when you use a lightweight training bike your mind & body becomes lazy & will only allow you to push yourself to what you believe you can do. To do this you need to either train with a much heavier bike up mountains in 52T-13T gearing or put leg weights around your ankles & also do the high gears in the mountains going very slow off the saddle. When you are training on a weighted bike & legs then swap them for your racing bike it will be like you are pushing nothing every time. The extremely high gear you trained on will help with sprints, high cadence & low speed for 80km - 160km will help with your endurance in long road races at the front of the pack. I lost my chance at the 84 Olympics due to a hit & run accident which broke my back so it basically wrecked any future of cycling.

It is little known, but means of tripping the boundary layer (via "trip strips") were actually used in 1982 by the US Olympic cyclists. I was an engineer on the team that developed the first of the aero bikes used by the US team for the '82 Olympics, under Dr. Chester Kyles. Rules were different back than, and it was not such an obvious bit of tech, so likely no one knew what we were up to back than. Wind tunnel tests confirmed measurable reduced drag over ordinary looking typical frame, component, and helmet shapes with the addition of a trip strip. Your description was not quite accurate BTW, though granted it is a complex fluid mechanical process that is not easy to intuitively understand. It does not reduce turbulence, but actually increases it slightly. It has been found experimentally that within certain narrow Rynold's number ranges if you slightly increase turbulence on the surface, the net drag actually goes down. The Rynold's number is a measure of a kind of "turbulence" rating. It does not work at all speeds or with all areo shapes, but if you are trying to reduce drag within that particular Rynold's number range, it does work. Bicycles (and golf balls) just happen to operate right within that special range.

Mount a playing card to the seat stay with a clothes pin. Angle the card so that one edge just touches the spokes of your back wheel. Attach a sticker which reads “turbo” to the seat stay just above or below the point where the clothes pin is mounted. The sticker is a vital component. Without the sticker, you will not experience the same amount of boost.

Trip strips are actually there to trigger turbulance, not prevent it as commonly thought. They work by starting up the turbulent flow early on which in turn reduces friction by breaking up the boundary layer of air closest to the surface of the frame and therefore reducing drag.
@kiva7296
5 жыл бұрын
Mmpeaceofcandy May be its more clear like that: trip strips trigger laminar to turbulent boundary layer transition earlier. Turbulent boundary layers are more energetic and they tend to resist flow seperation. Due to reduced separation and wake region around the bike, drag is reduced. This is happening even though turbulent boundary layers have more friction in it. Try to have a more streamlined position on the bike 😃

Geek knowledge: Trip strips actually don't decrease turbulence, they increase it. Laminar airflow has a tendency to detach from the frame tube much sooner than turbulent flow, which causes higher air resistance due to a lower pressure behind the tube. So you actually try to increase the "bad" turbulent flow because in this special situation, it is better than laminar flow.

Trip strips actually doesnt work like dimples on a golf ball, they allow to control where the boundary layer separates from the surface. They're a bit comparable to deflector placed on cars at the rear (like on the recent Land Rovers). I should add that Jon placed them on the right tubes but not at optimal places, the frame is already very aerodynamic and probably doesnt need trip strips. However it would work much better on frames with round tubes if you place them correctly. PS : I did my final year research project on analysing aerodynamically where to place a deflector on a cylindrical body.

Bryce Dueck Makes sense. By switching to a more efficient gear ratio in terms of chain alignment and “feel”, keeping a good tempo should be more comfortable. And comfort is key. You won’t keep to a certain wattage or cadence if it feels awkward to you.

You certainly can quantify it: www.bikeradar.com/road/gear/article/friction-facts-free-speed-from-proper-shifting-44016/ And it's about 2.5Watts, which will mean you go about 0.4% faster, but most of that is not from cross chaining but from using the 11t cog. The big big cross chain combination only loses about 0.75watts. If that's a massive difference to your perspective then great, but for actually winning races or just getting around effectively, gears are MUCH better. And obviously for going downhill fast, the drag of a freewheel is much less than the wind drag of holding your feet up in the air, never mind the drag in chainring and bottom bracket while your pedals fly around at 200 rpm. Fixed is for fashion, not for cycling.

“Remember the days” (I sound like an old man - I’m only 28 lol) when you used to tell your dad that it’s a fast bike, and he’d say “it’s only as fast as your legs”! My suggestion: pedal harder!! The physical weight of the bike (including heavier aero wheels) doesn’t have an impact on flats and aerodynamic efficiencies are only achieved at higher speeds, which in Beijing in absolutely impossible btw!! I can definitely notice the gains in a slammed poison (simply by maintaining your cadence and observing how your speed changes relative to your position) but is not something I can take advantage of very often due to where I live. Initially, I was skeptical; however, it’s surprisingly comfortable!
@acousticgearhead7820

Yes, ruin your position and comfort to save 50W while loosing 100W because you can't put your max power out anymore. Instead of stupidly narrow handlebars, try tribars where allowed. Alot faster and definitely more comfortable. And if you actually need to corner you can still resort to nice wide handlebars. Another option to the dinnerplate-chainrings. Maybe consider using appropriate gearing for your body instead of imitating the pros and ruining your knees. Try building a custom cassette with a larger smallest sprocket. I run a 13-36 cassette with a 48-32 on the front for gravel. Switch to 50-34 or even 52-36 and you got decent gearing for mostly everything if you are not at the high-performance end of the sport. Larger sprockets at the back also have a higher impact on efficiency than on the front because the percentual difference in "wrap-radius" is a lot higher. I appreciate these videos for showing literally EVERY option you have, but PLEASE atleast point out the drawbacks as well. There is more than enough misinformation in the world today...

Which is why the word optimization exists. The best solution will not be at your highest power output. It will be at the point where the drop in power output per mm is equal to the reduction in wind power. Above that point the wind gains will be higher than the power losses. However this is also why you should move your seat and bars forward. You can get a more open position for the same aero profile.

Trip strips do not act to reduce turbulence. They accelerate the transition from laminar to turbulent flow at supercritical Reynolds numbers. Since a turbulent boundary layer has a distinctly different profile to the typical Blasius laminar boundary layer, adverse pressure gradients in the flow occur at a later stage in the flow and so flow separation is delayed. This means that the wake angle is smaller and hence rear pressure is reduced less, resulting in lower drag.

It's odd that this channel is called the Global Cycling Network and all the topics discussed are about racing bikes, or getting faster, food for performance to make you faster, what the pros do, or be like the pros, racing oriented new tech. This actually discourages a lot of people from cycling and I feel if this channel is trying to promote cycling then more emphasis needs to be given to the practical side of bicycling and the bikes or cycling that most of the population are going to relate to. Show people more ways to use their commuter bikes as not only an exercise bike or part time recreation gadget but as transportation and utility means of going shopping and such. How to use their bikes to be more social and interactive. Cars separate people from one another and I think so does focusing on training on a bicycle. I never spent more time alone as I did when I was always trying to get faster on a bike. I'd like to see more people getting healthier and using their bikes as a form of transportation and feeling safe doing it. Then we would also most likely see a decline in road raged car drivers. We would have more people getting more involved in changing their cities to be more bike friendly. Either that or you guys should change the name of the channel to something else like Global Sport Bike Network.

@@MicroageHD it means you ultimately have the potential to be faster than someone with, 50/11 and 175mm crank. Ex: to hit 64 kph with a 50/11, you need a cadence of 111. To hit 64 kph with a 80-11, you only need 70 cadence. the longer crank increases torque force; decreases your watts, and since you're pushing a big gear, cadence isn't as big of a factor. this is especially true for downhill. you'd spin out at 60 kph with a 50/11. with an 80-11, you'd be hitting 70-80 kph

Instead of slamming the stem and riding on the hoods, how about you leave the stem where it is and ride on the drops?
@nicolasjulou8081
5 жыл бұрын
If you ride on the hoods with the elbows bended you have more support on the wrist and even the forearm. The aero position is a lot more sustainable this way and can be as aero as the drop if you are low enough and long enough on the bike. If you let your stem high and ride in the drops all the time, it's fine, but you will probably experience wrist pain. Furthermore, with a slammed stem, the drops are low enough to get you in that aero sprinting position a higher cockpit would not allow.

@@nicolasjulou8081 I beg to differ, that aero hood position with the lower arms parallel to the ground is far more difficult to mantain than simply riding in the drops and is also more susceptible to make your wrists hurt. I can ride for 10-15 minutes straight in the drops without any discomfort whatsoever, but everything hurts after 2-3 minutes in the other aero position. It is more aerodynamic though, no argument there.

With regard to Aero drag. Mini Vortex generators or model airplane stall strips would be something you could play with. Also here's two interesting links. www.boardmanbikes.com/bb_en/why-boardman/technology-1/r-d/aerodynamic-surface-trip.html wingsandwheels.com/turbulator-dimple-tape.html There's a point of diminishing returns on handlebar width, it's not going to be a linear gain as you go narrower. You have to test a whole bunch of different sizes and configurations in a wind tunnel to get the actual coefficient of drag numbers and subsequently the Savings in wattage.

If slamming the stem forces you to exceed your hip, glute, or hamstring ROM, then it will not be faster. Aerodynamics are useless if you cannot sustain power output for the required ride duration. Bottom line, get a proper bike fit. One that involves a physical assessment in order to account for body structure and range of motion. Simply mounting up narrow handlebars and slamming the stem might slow you down and might also cause serious injury to the rider.

well said. i'm tired of seeing GCN bro-science making people into believing that going lower, narrower and longer would make them faster. in fact, it will make them go slower and end up in a hospital. it's funny to see world's top pros have more relaxed, upright fit compared to many wannabe amateurs.

rararroro Not all pros have a more upright position. Many are quite low, BUT....they are young, flexible, and PROS. And not all pros are going full slammed aero tuck all the time. Because not all people (including pros) can ride that way for hours on end.
@bigring6424

This depends on how you define exceed. In the end exceeding ROM translates to breathing restriction because you'll keep your hips open but compress your chest to get there. But regardless, as power starts to drop faster there will be a point where it drops faster than aero gains increase. That cross-over is the optimal. One might say that's already beyond your ROM. Of course this applies if you're bent on going as fast as possible. Nobody said winning races is the most pleasant way to ride.

Big Ring Range Of Motion is the angle of maximum extension and the angle of maximum flexion of any joint or joints in the human body. It is limited by bone structure, tension of the muscles, tendons, and ligaments, injuries, and surgical modifications. After fit corrections are made, output typically will drop for a period of one to three weeks depending upon ride intensity and durations, then once the rider has acclimated to the new position power output typically rises above pre-fit levels. This is why you cannot use power for fitting. I am a Retul certified Fit Tech.

A. Garcia, everything you said is fine, but in the end there is still, in the long term a position that pushes past the edge of your bodies limits and reduces power but improves aero, and the optimum for a TT will be somewhere on that slide. No, you can't find that in an hour on a wattbike in a fit shop.

I dont think the trip strips will work on bikes very consistently. I think what they are supposed to be doing is acting like a gurney flap on racecars - introducing a turbulence , that keeps the air from creating a prominent tear-off edge behind - in this case - the headtube or the seat tube (or in case of racecars use that turbulence to create more downforce). But this effect is highly dependent on the airspeed and relies on the flow around the structure being as close to laminar as possible - so the stripes around the seat tube most likely have absolutely no effect. The stripes on the headtube can work, but you have to consider, that they also introduce drag. The engineers that designed the frame made it as smooth as possible in order to reduce drag and turbulence. And while the stripes may work, they surely mess with that surface quality and most likely you will end up with worse overall airflow than without them. Also notice how the headtube is not round, but has an egnineered cross shape. This is to improve airflow and those shapes are really fragile to changes. Meaning if you change the shape even slightly - it may not work anymore. So adding those strips to modern frames is 99.99% not a good idea. I think the aerodynamicly best bike is the bike you feel most comfortable with (at least as long as you dont have access to a wind tunnel ;D) Edit: apparently its "strips", not "stripes" ^^

Perhaps to something like 36cm C2C, with a reach of 70mm or lesser (I have a petite build with a rather short torso). Where can I get any? Most brands only make 40cm narrowest. I've also heard of custom handlebars, but I don't know who makes them.
