The 30 mph Aero Challenge - How Fast Can Ollie Go?

Показать описание
Cycling fast is the goal of all cyclists, but how easy can we make it? Ollie has teamed up with Nopinz to find out. Beyond training and hard work, there are aero gains - new aero bike, deep rim wheels, aero bottle cage and aero helmet. But many people don't think about their clothing! Will a custom Nopinz skinsuit finally be the key to Ollie reaching 50km/h? How fast can the Aero Dork go?!

Can I just say that, as time has gone on, Ollie has become a really good presenter. Great enthusiasm and "down to earth", enough of a nerd to relate to many of us and a good sense of humour. Keep up the good work.

In order to go 48 km/h on a smooth flat road on a calm day with no interfering traffic at or near sea level, you need a ratio of Watts/CdA of ~ 1500 (slightly more if the road isn't flat or the surface isn't smooth, slightly less if you're riding on a dual carriageway with lots of traffic to push you along, a fair bit less if you're riding at altitude). So if Ollie had averaged 326 watts, his CdA would had to have been in the range of 0.20 or 0.21 m^2, which is a nice improvement from his starting CdA of 0.26.

He even used long aero socks. He's more dedicated than when he did his hour record

As much as Ollie gets kidded about his biking fitness that was some seriously impressive power. Well done Ollie. If only us mere mortals could go as fast as Ollie.

What ALWAYS amazes me is the ability of the the presenter to speak clearly and with well controlled modulation while explaining technical details as he pedals his bicycle at speed! That takes a special sort of person!

Solo effort, no way to get dropped :D

Nice video. I can see several comments regarding:
1. Facial hair. Facial hair doesn't seem to matter as much as arm or leg fur, especially leg fur since the lower leg is a cylinder that churns through the air while the face is mostly "static."
2. Recumbents. Most unfaired recumbents have (surprisingly?) higher CdA than Ollie was reporting on this TT bike. Only a handful of unfaired recumbents have CdA < 0.20 m^2, and they often have other issues including high drive train losses and/or less than optimal tire rolling resistance. The only recumbents that are clearly better than an optimized rider on a modern TT bike have fairings -- streamliners can have a CdA < 0.03 m^2 -- but most commercially available recumbents have a CdA in the range of 0.25 - 0.35 m^2. As a reference, on Ollie's original road bike, he reported that his CdA was 0.26. A few low racers have CdA's in the range of 0.17 m^2, but they often achieve that with odd tire sizes, long chains with idlers, and reduced turning radius.

I want to see those that make fun of Ollie, because he has been dropped in other challenges, to ride that bike with the same average speed. He was not a pro cyclist and he is a machine. GCN is very lucky to have him in the team, very knowledgeable and makes very good and entertaining videos

Wow, aweomse video! One of the most informative and interesting video's you guys ever produced! Super relevant for me as i can relate to the numbers. Thanks!

"I want to be as legit as possible" I like this attitude by Ollie!

The best part was the sense of joy Ollie had at the end when he achieved his goal.

Cracking video! Besides Ollie’s charisma I really enjoyed the science and the effort put into making this clip. Grand tours are won and lost in a time trial.

That was a great bit of practical science from the GCN team and as always Ollie adds his own enthusiastic twist to the production. Chapeau Ollie and well done !

Kudos again Dr. Ollie for not only your accomplishment but using and explaining the maths and science behind your attempt. Also using the Siborg;s HIVE-born technology was an added boon, but your human updates were impressive as well. Thanks you for pointing out the edge sparking water gives humans in their quest for hydration. Love the vids and am looking forward to the Siborg smashing all expectations. All will be assimilated. Resistance is Futile. The HIVE requests the link to said updates to the Siborg's machine.
