    How come there’s no fucking mention of sexism against fucking Xavier Disley and fucking James Bracey? His attack on their fucking credentials were far more scathing.🙄

  2. syamsul arifin on October 9, 2020 at 3:58 am

    Great sharing

    Dr Disley is claiming Carbon fibre chainrings he sells are comparable to wear life of aluminium chains and that they have superior friction properties. 
    CFRP has a hardness of 16BHN.
    Aluminium 6061 has a hardness of 95BHN.
    Aluminium 7075 has a hardness of 150BHN.
    This guy is a fraud and a liar.

    Imagine reporting Hambini for some mean words. Unsubscribed.

  6. Quinn Taw on October 9, 2020 at 4:01 am

    Blatantly and objectively bad science. Sad.

  7. Peter Grant on October 9, 2020 at 4:05 am

    What a load of horse s#@+, there is nothing scientific or relevant about that content – taking areo biased road helmets and testing them in a velodrome, using questionable data fields. Conducted by a coach who doesn’t appear to have any credentials in aeronautical engineering or testing. And the most insulting part is the so called journalism – it just regurgitated the marketing copy from the manufacturer.

  8. quality clickb8 canser on October 9, 2020 at 4:06 am

    Anyone, with or without a degree in aeronautical engineering, can tell you that an ENCLOSED VELODROME will not have air that behaves the same way as it does outdoors…. when you are outdoors, everything you pass interrupts flow… not even close to science.

  9. Ever Ruiz on October 9, 2020 at 4:07 am

    way too much talking just show me the results… =)

  10. Robert Gardner on October 9, 2020 at 4:07 am

    Your site is now no different from GCN, BikeRadar, slotwitch, or roadbikereview. All 4 sites are loaded with bullshit artist shills for marketing based cycling products whose site operators and regular forum participants desperately attempt to portray themselves as being honest, objective, aerodynamic experts, independent, unbiased, and/or a slew of other qualities their delusional minds convince themselves they are. In actuality of course, they are rarely if ever any of those things.

    Hambini is better than all of the previously mentioned shill site hacks noted above. He backs his claims up with actual tests, proven engineering principles, and sound unbiased facts. He’s neither a bootlicker for the marketing departments of cycling component makers, nor a gullible placebo infected idiot who chose to buy into the marketing crapola of Zipp’s decal covered dimples as one of dozens of such laughable examples. Hambini’s approach of unbiased engineering analysis of bike frames and components is an entirely foreign concept to the 4 joker sites and their “regular” forum participants noted above. Their idea of an “aero expert” is a clown whose entire knowledge of aerodynamics is evidenced by the fact he was part of an aero design team who designed a wheel with some “supposed aero dimples that they then covered with logo decals or another self imagined expert/idiot who built some wheels from pre fabbed parts and by doing that suddenly thinks he’s an aerospace expert or even the equivalent of a first year undergrad aero engineering student. Hint: he isn’t!

    ROTFLMFAO if you choose to consider such dubious sources of information “informative.” I’ll take Hambini and his approach over the hacks mentioned above 7 days a week. 😃

  11. Nade Ruadan on October 9, 2020 at 4:10 am

    You lift should lift your journalistic standards and stop selling out to advertisers instead of taking Hambini to court for hurting your precious feelings.  Rampant Feminazism IMO. Get the ban hammer out, wouldn’t want to let people know what you are really like.  You do yourself no favours by being so precious.

  12. Angga ZID on October 9, 2020 at 4:12 am

    I was here because of Hambini. Thumb down for you guys.

  13. jm D on October 9, 2020 at 4:13 am

    most comments here agree with Hambini

  14. Allan on October 9, 2020 at 4:14 am

    Not a lot of wind in the velodrome, but certainly a lot of hot air!

  15. colin doyle on October 9, 2020 at 4:15 am

    just going for an hour long ride from London to Brighton and back, will try not to take much more than an HOUR lets put it on STRAVA just to rub everybodys nose in it

  16. Richard Allesee on October 9, 2020 at 4:15 am

    You have lost your credibility

  17. Jay Bonner on October 9, 2020 at 4:16 am

    Cycling weekly is a joke , you are just getting paid by your mates to promote there stuff. People are dying yet you think you are so special that you don’t need to follow the rules. Disgusting editors both of you. Nothing to do with gender but the woman is not fit to be a public figure

  18. Mandy on October 9, 2020 at 4:18 am

    Poor testing protocols leads to GARBAGE IN, GARBAGE OUT! P.s. what’s with the overt displays of sexism – “token attractive woman”. Total rubbish!

  19. space monkey on October 9, 2020 at 4:22 am

  20. Lyndon Pung on October 9, 2020 at 4:23 am

    Lol Aerocoach what a proper bellend

  21. Simon R on October 9, 2020 at 4:26 am

    The negativity in this comment section is truly horrendous. I don’t know what Hambini said in his video, but if watching him has that kind of effect on you, you should really stop and go for a ride instead.
    I really don’t get all the comments saying that "the velodrome isn’t comparable to the outdoors"… duh, neither is a wind tunnel. The main difference is yaw angle caused by wind direction, but that was simulated to an extent by having the riders turn their heads. Obviously it is impossible to have accurate and consistent aero measurements on the road, and a controlled environment can never be exactly similar, indeed it is meant to remove some variables from the equation.

  22. Bike Curious on October 9, 2020 at 4:27 am

    feck off karen

  23. DC _Cycling on October 9, 2020 at 4:29 am

    This is a massive let down from you guys at cycling weekly. If MAB can’t clearly take a bit of banter she’s in the wrong field of work…

    Playing the sexist card is a joke hambini is the same in ALL his videos reguardless of your sex, race or religion.

    All his done is shown that your testing and many others testing in the bike industry is marketing bs..

    I think u need to stop with this personally after following you for many years I have now unsubcribed along with thousands of others….

    MAB has done cycling weekly no favours at all imo. It went downhill after Bridgewater went.

  24. doug brown on October 9, 2020 at 4:29 am

    This is the most irrelevant video that I’ve ever seen! As someone else said, this is marketing. It is product marketing and product placement. What garbage! Velodrome compared to the real world … get REAL! And,oh, yes, as well, Hambini was totally correct in his criticism of the methodology of this aero helmet test.

  25. T4 Tips & Guides on October 9, 2020 at 4:30 am

    This video is very misleading, I hope no one takes it seriously.

  26. CaptainPrice29 on October 9, 2020 at 4:30 am

    these guys should consult Hambini before publishing any videos

  27. colin doyle on October 9, 2020 at 4:31 am

    call the cops

  28. Dangerous One on October 9, 2020 at 4:33 am

    The only non-aero helmet in your testing came in 2nd best? Did you get any angry calls from the losing manufacturers?

  29. shinracorpable on October 9, 2020 at 4:35 am

    Just admit you make entertainment content and stop calling it reviews and get over it.

  30. Wei Liap Lay on October 9, 2020 at 4:35 am

    They have no idea what they are talking about

  31. CaptainPrice29 on October 9, 2020 at 4:36 am


  32. Robert Chung on October 9, 2020 at 4:36 am

    First off, it should be unnecessary to say this but I have no connection with Cycling Weekly or Aerocoach (or Hambini) though I’ve met Xav and I’m familiar with the testing method that he uses.

    Second, I’ve done a fair amount of testing outdoors on real roads under real world conditions, and also on the velodrome in much more controlled conditions — and also have observed wind tunnel tests of the same equipment. In general, the results from all three are very close — the differences are in the amount of time it takes and how easy it is to test different setups, not in particularly in the CdA you get. For example, a nice thing about testing on the road or velodrome is that your legs and body are moving and you’re turning your head left and right and up and down whereas in the tunnel you’re typically much more static. That said, the proof of a pudding is in the eating of it, and the predictions of speed for power you get in the tunnel or in the velodrome (or in field tests) match up very well against actual performance.

    Third, one needn’t be an aerodynamicist to *measure* aerodynamic drag, just as a physician needn’t be an electrical engineer or trained in fluid dynamics to measure heart rate. The people who designed the Track Aero System used in this test are indeed engineers (with PhDs in Aeronautical Engineering), statisticians, and physicists.

    In summary, I think this video is actually pretty well done, and there is good information here.

  33. Dekab naeb on October 9, 2020 at 4:36 am

    Nonsense video. Though hambini may have been unsubtle in his criticism his analysis was reasonable. Disliked.

  34. Nade Ruadan on October 9, 2020 at 4:37 am

    If you want conditions which match outdoors go outdoors genius.

  35. Kionne Potter on October 9, 2020 at 4:39 am

    Cycling Weekly, is it true you ban aerodynamic experts from commenting on your aerodynamic testing videos? If yes, why would you do that?

  36. Nev Kemp on October 9, 2020 at 4:39 am

    "its won a lot of races"…… seriously. Helmets do not win races. Riders wearing helmets win races. Now unsubscribed!!

  37. Neil Bathe on October 9, 2020 at 4:41 am

    In your expert reviews in the future, would it possible to include the relative advertising revenue each brand pays to Cycling Weekly, so we can have a relatively objective scale to apply to the efficacy of the actual product?

  38. dragade101 on October 9, 2020 at 4:42 am

    Hahah. There is free speech. well the idea of it. But what "third parties" do on youtube is freely up to them. Like they actually follow up the first time around and talk about it their reasoning. Cant say you have done the same. Like honestly I would ask if you are racist yet I doubt this conversation would go anywhere as it would be censored.

    I do challange #MichelleArthursBrennan #JamesBracey or #CyclingWeekly to have an open discusion that isnt censored.

  39. Chris G on October 9, 2020 at 4:42 am

    I feel sorry for CW. Looks like they’ve opened a bag of worms by sueing ppl. All they’ve done is given free marketing. They could have handled the situ way better

  40. DS on October 9, 2020 at 4:47 am

    Her voice sounds a bit too nasally, are you sure she doesn’t have any sort of viruses that could spread for all the people working there? It’s for the best of all that you don’t work closely to other people during a worldwide pandemic. Right, this is essential work, just like riding cross country in a bike for several hours and filming also during a pandemic. Got it.

  41. Paul Roche on October 9, 2020 at 4:47 am

    Hambini knows best

  42. Ben WS on October 9, 2020 at 4:48 am

    BREAKING NEWS – NASA has stated they will use a velodrome to perform their testing and train astronauts. Apparently, being inside the velodrome is just like being in space. 😉

  43. Bharat Singh on October 9, 2020 at 4:48 am


  44. Retro Dude, Old man on his bikes on October 9, 2020 at 4:49 am

    This video is total bs. Hambini is correct. And no it’s not useful it’s misleading

  45. Louis Pitt on October 9, 2020 at 4:49 am


  46. glen riley on October 9, 2020 at 4:50 am

    Hambini (age 5) ripped Benedict apart he has not a clue what he is talking about. But unfortunately, Michele /cycling had youtube remove it 🙄

  47. Christopher Railwah on October 9, 2020 at 4:51 am

    Lost a sub . Bad look going after a fellow YouTuber. Acknowledge your mistakes or provide data to support your claims

  48. Darrin Cunningham on October 9, 2020 at 4:51 am

    This is bullshit. As an aero engineer the science is crap!

  49. Cycling Weekly on October 9, 2020 at 4:53 am

    We have had some comments on this video instigated by a third party on YouTube, which we would like to address briefly here.

    1. We welcome criticism; all passions benefit from a multitude of voices, and criticism helps us do our job better. However, we do not condone personal abuse, particularly when that abuse stems from a difference in gender, background, race, religion etc. Life is stressful enough at the moment without our employees and associates logging in to find horrible and highly personal comments from someone they have never met or had any contact with. We hope everyone can agree about this.
    2. All of our branded content and promotional videos are clearly marked as such.
    3. Although it isn’t directly relevant to this video, it is being mentioned by some commenters so: we absolutely support the lockdown in place by the UK government regarding coronavirus. Cycling is explicitly permitted by the regulations in place at the time of writing and we are abiding by them at all times. We do not view cycling as an inherently dangerous activity, and by following social distancing at all times we have never placed ourselves or others at risk, and we are riding with extra care in order not to place the NHS under any strain. Moreover, it should not be assumed that videos were filmed on the same day as they were published as we film ahead of time in order to reduce strain on our small team.

    We hope the above makes sense, and we’d like to thank all of our magazine readers, website visitors and YouTube subscribers for their support during the current coronavirus crisis. We feel that our aim – to inspire, inform and entertain cyclists about their passion – is more important than ever at the moment, and we’ll continue to try our hardest to deliver in these difficult times.

  50. Ray Thorn on October 9, 2020 at 4:54 am

    Hahaha yep……you’re screwed #freehambini
