  4. This video is way to scarily relatable for me. I have had two mild concussions over the last 3 months that have driven me crazy. I have horrible short term memory now which i have no clue weather it is going to improve and on top of that no one seems to certain as to whether it's safe to be back on the bike. Does anybody know more about the stress issues he was talking about (4:30) because I think I might have them? Concussions are really serious now that I'v had to deal with two of them and I advice everyone to invest in an overkill helmet with actual research put into it because I don't know If I trust my Bell super DH anymore.

  5. I like everything being said in the video, but I'd want to add one more thing: dont't buy non-MIPS versions of helmets anymore. The Virginia Tech university does independent crash tests of bike helmets and has made a top list that you can view online (go to: helmet.beam.vt.edu, then select bicycle). In their tests all the top scoring helmets have either MIPS or Bontrager Wavecell technology. These don't have to be expensive, some cost less than 100$ dollars and outperform 200$ POC helmets without SPIN technology. I'm not saying all MIPS helmets perform good, you'll have to check on their website, but in general these helmets offer way better protection. I kinda wish this was mentioned in the video or maybe GMBN can mention Viriginia Techs research in a future video. This way, many viewers will be informed of this safety rating. Otherwise people have no way of knowing how safe a helmet is before they buy it. A positive thing is that the top scoring helmet only costs 75$ and shows that safe doesn't have to mean expensive!

  6. Dave Mirra, BMX freestyle and x games hero had so many concussions that it was the reason he committed suicide, it is a real concern for bikers and awareness must be a part of our sport. Thanks GCN for bringing attention to this sad part of cycling.

  7. Had a big one yesterday, front wheel folded and I hit the floor before I could leave Go of the bars. Little headache today, my shoulders and ribs though, that’s another story. I was debating full face or trail lid, so glad I opted for the full face. Thank you 100%. Other brands are available 😂

  8. I had a nasty OTB on my mountain bike 2 months ago, I got diagnosed with a grade 3 concussion as well as a lot of other injuries. My broken bones are just about healed but as a result of the concussion I have been suffering with BPPV :s

    Reply

  9. Had one about 8yrs ago I got knocked out, only for a few seconds ,put up with intense headache for a week before I went to my doctor he sent me staight to hospital.The doctor I saw there went completely mad at me for not going immediately, luckily for me all the scans and test came back ok .He said my helmet had done it's job . DON'T BE A DOUGHNUT WEAR A HELMET

  10. Just speaking from personal experiences… Wear your brain buckets! And wear good ones too if you can, please — although something is always better than nothing, it's often a case of "you get what you pay for" when it comes to protecting against concussion (and not just superficial wounds).

    Reply

  11. I have a question is it better to drive a wheelie with a hard or soft damper?🤔 And nice video 👍

    Reply

  12. Most important info for MTB at the end, ride within your abilities and don't take unnecessary risks. Send it culture with advanced/pro riders making things look easy with their skills is hard to resist the urge to push it.
    But, we all do. The buzz of landing a newer bigger gap or trick is why we take chances? Faster, higher, further, (obvs with more roost) All we can do is protect our bonces with higher quality helmets. @gmbn Maybe it's time for a name and shame video of the brands and models to avoid? Won't be popular but if it stops one serious injury it's worth it right? Or some things to look for when buying helmets for more advanced riding? We all try to balance safety with economy as not everyone can afford a POC helmet. Especially not for every member of the family.
    Great vid, again (even though presented by roadie!) Made me think about concussion a lot more, so one score there.

    Hey, at least we are not boxing, it could be worse!!

  13. My mate went over the bars and broke his neck, he was partially paralysed and comitted suicide a year later.
    I guess its far too much to ride with a neck brace..but Id like to see some advice how how to build up your reactions to ensure you automatically protect your neck when over the bars faceplanting.

  14. Great video about a very important topic! To be aware of the danger of head injuries and knowing the symptoms and longterm issues is important for every rider. This video explains all of this really well and quite indept. Good work!

    Reply

  15. Some new info: if you get a concussion you need to shut down for at least 5 days, no t.v. internet, or anything that uses brain power..darkened room..just rest

    Reply

  16. Literally yesterday got into an accident. Slammed my head against the ground. Luckily I was wearing a helmet otherwise it could have been a very different story. Thankfully now I'm only dealing with roadrash and bruising. I've been saved by cycling helmets twice in my life now. Always wear a helmet.

    Reply

  17. I'm skeptical about the claimed protective benefits of a helmet. Even the new technologies like MIPS probably shouldn't be talked about as if they'll protect you from smaller concussions. Instead, it should be said that they're just better than nothing. I wish I could find the article, but there was a study of snowboarders and head injuries which appeared to show that helmets really only protected against cosmetic damages and didn't significantly reduce brain trauma. In other words the concussive impacts still transferred through the helmet enough that it didn't matter, and it really doesn't take much force to cause an injury. It's probably true that MIPS and wavecell do help disperse forces better, but I'm doubtful that these should be considered adequate prevention of injury rather than (once again) better than nothing.

  18. Just to be clear helmets cannot stop concussions, however they can stop you splitting your skull open so wear one and check yourself out if you fall off with one on because you can still be concusses

    Reply

  19. Great video, but first statement is not so accurate. Non impact crashes where the brain can strike the inside of the skull and traumatize the brain even without the skull coming into contact with anything

    Reply

  20. #askgmbn can helmets without mips still protect your head. Are there helmets out there to avoid getting. And should one get a neck brace if they get a full face helmet. Finally can a cheap helmet work or should one always invest into a higher end product like poc

    Reply

  21. As someone who got a concussion little over a month ago, it fucking sucks.

    You look completely fine, but can't do shit.

    Reply

  22. Dump the bike if you have time to react and feel like you’re about to wreck. As much as it hurt financially, I avoided a much worse wreck by ditching and letting the bike take the damage. I was able to mitigate my injuries by controlling my landing. I’d rather have scars than an injury that will keep me off the trails permanently.

  23. My front wheel slipped on damaged road which had a small edge while turning directly into my work place. Was on my gravelbike and was wearing a 2nd generation Met Parachute. Despite riding at about 20km/h or so while turning I broke the radius head in my ellbow, my cheekbone and my eyesocket. I dont remember how it exactly happened. Got a connuction too. The main symptom I noticed was that I was often extremy tired weeks after. I like to believe that without a full face helmet it would have been much worse. I can really recommend those for city riding. Replaced it with a Fox proframe. Sadly I can't use it on training rides on the road because I need to be able to drink and eat while riding.

  24. Next week: Understanding Mountain Bike Concussion while riding a Mountain Bike with a Concussion which was caused by watching the Understanding Mountain Bike Concussion video while riding a Mountain Bike trying to avoid a Concussion

  25. Great video, very informative and very important to all people. I see so many people on my commutes to from work not wearing helmets or wearing them improperly it is scary. I will not get on bike with out a helmet, I have had that philosophy for over 30 years. I like say “ I wear a helmet when I ride my bike, so I don’t have to wear a helmet every day if I don’t.

    Reply

  26. As a radiographer working in a trauma hospital in Australia, and receives a significant amount of cyclists and mountain bikers post fall, thank you for highlighting the significance of concussions and what the industry is doing to minimise it 👍

  27. This is very interesting, could we see a video on how to keep your bike safe in terms of storage and locking techniques so on

    Reply

  28. I’m so glad you made this. My injury was a severe TBI instead of a mild one, which concussion counts as, but my helmet saved my life. I have permanent damage, and I relearnt a lot, but I lived to ride again! Wear your helmets!

    Reply

  29. Gotta risk it for the biscuit I guess but definitely risk it while wearing the proper protective gear.

    Reply

  30. I washed out on the first corner of the first run of the day at skyline rotorua which resulted in a mild concussion, my advice is learn the grip before riding fast.

    Reply

  31. 5:35 I was waiting for this words. The only thing I'd add or correct is not to use "add up", repetitive brain injurries synergize, though the MD elaborated it later. He elaborated it even before talking about inflammation, which goes wild after the second impact.

    Reply

  32. You can get concussion even without direct impact at your head: any fall, especially hard, must be assessed for the possible consussion.

    Reply

  33. Great vid. Got me thinking, Like everything else in life there are a ton of options when it comes to buying anything. There are many helmet manufacturers with MIPS and versions like it and are certified or pass a test. Is there a thresh hold in testing helmets where they pass a test or way surpass the expectations of said test and are way above the rest? I guess my question is because a helmet has MIPS it is the best regardless of manufacturer?

    Reply

  34. One time at my local pump track I basically cased a double with just my back tire and it bounced forward making me go over bars, landing on my face with it scraping on the ground , and then my bike landing on my leg. I kept falling over randomly and I don’t remember anything from the start of the crash to the next day. I only know how I fell because my brother saw me fall.

    Reply

  35. Yep, twice as a youth playing Rugby, three times (one bad) from cycling, in the last 5 years – those were all whilst mountain biking.

    Reply

  36. Great awareness vid! My 2 Bontrager MIPS helmets have saved me and my friend from serious head injuries. Always wear a helmet, especially with MIPS.

    Nice to see Chris Opie on GMBN. Still need to see proof that he can ride a MTB.

  39. I got a concussion from water polo and i was out of school for a month. My balance and focus and things like that were way off

  40. I’m 14 and I recently got a concussion playing AFL. I was really worried that I wouldn’t be able to go Mountain Biking for ages so I did hours of research but never got a proper answer. This video helped me out and it’s a no brainer that you should always wear a helmet.

  41. Went to Trek World in Karpacz in Polen with a collegue. He crashed hard testing the 2019 Slash 9.9, shattered his helmet (lightweight road helmet), and we had to carry him down the mountain for 40min until we got cell service to call mountain rescue. This is 9 months ago, and his still only working 70% and is easily fatigued and gets headaches all the time. Walks around work with a noise canceling headset all the time to block out noise.

  42. As a head injury therapist I can't agree more with the information in this well presented video. Will be recommending some of my clients watch this. Still amazes me that British cycling still produces videos of cyclists without helmets when the advice is clear on the reduction on the consequence after a head injury. Thanks GMBN keep it up.

    Reply

  43. I cracked two helmets within a month. First time I had headache for a few days afterwards, second time just walked away with no pain. Helmets saved my day. I haven't hit my head before or after that so even though you think you'll never fall that unlucky you just might. Wear helmets! Messed up hair is the new thing 😄

  44. I have had a crash in 2011 which cut my nerve to right inner ear and a concussion and whiplash. I had some treatment but was never got advice, I did what describe in the video and carried on riding, since then I had 3 more concussions. I came in August because concentration problem and broke my arm tried riding again last Tuesday and fell off. It being taken seriously now but this a great video to high light the problem, I will never be able to work or go out because of the symptoms described in the video so take care people!

  46. Jerry quarry was a great professional boxer who can't remember how to tie his shoes. Literally. Look him up. I concussed 50 years ago at 13 and again at 27, now 64. I think I have consequences from those 2 incidents.

  47. 2 From rugby while in school
    1 from road bike commuting (crashed into the back of a van)
    2 from motorcycle crashes
    2 from falling off the mountain bike
    and 1 from playing squash

    Admittedly all over a span of 30 years but I am sooo f*cked!

  48. Great video! A helmet has saved my life mountain biking. Better trashed helmet then a dead head

  49. lol.. channel that routinely shows "sends of the week" / "fails and bails".. / expert pro riders doing huge jumps / tricks .. now tells me to not crash / ride within my skill / comfort level..

    I mean.. no worries for my part ..I'm 49yrs old with arthritis and a variety of previous injuries.. I'm pretty determined to keep the rubber side down at this point..

    years ago a helmet clearly saved me from serious injury or worse… messing about on paved embankment in the wet back tire washed out on some leafs or whatever and went down 20~ft or so I could hear the back of my helmet bouncing off the concrete the whole way down.. must of been 8~times or so.. thank god it wasn't my skull bashing into the concrete the whole way down.

  50. I have had concussion a number of times, but had much worse non-cycling injury resulting in a TBI. That’s a traumatic brain injury. I worry about long term consequences, and struggled after it with awful fatigue and inability to cope properly with some emotions and empathy, I also lost around a months memory previously. My deep regret was not getting better treatment and crucially rest. I was chronically fatigued but forced myself harder into work. Subconsciously this was my brain avoiding complexity like emotions and falling into understood patterns like work. I never gave myself chance to fully heal, and the fatigue was a message to rest, not doing so hindered my recovery. I still don’t fully always feel the same, and this is a long winded way of saying ride hard, wear a helmet, and if you do get a concussion seek medical attention ASAP even if you don’t think you need it, rest, rest and rest, and let you loved ones know what has happened, they may spot things you don’t realise. In UK there is a great group called Headway, top guys. Hope this gets shown on GCN as well, tricky subject handled well.

  51. Thank you for this, not enough videos about the subject..and yes ive had a few and ive never been to the dr for them but i sure can tell some side effects from it

  52. That's really great info. All mtb riders should see this video, this is really important, I had no idea about the symptoms. Thank you poc you rock

  53. I got severe concussion just over two years ago. I was hallucinating the first 12 to 24 hours in hospital and became hyper sensitive to noise and light. Even the conversation level of the other patients in the ward was impossible for me and I had to go walking down the corridor to get away. The normal hospital noises made the place sound like a factory.

    After three days the doctor was prepared to discharge me if I had somebody looking after me – I'm widowed and live alone. So friends had me in their spare room for another week – it took that long until I could hold a normal conversation. They said my conversations were all over the place until then.

    Two years later and I still have problems with concentration and motivation. I used to write books but have not even read a book since the injury. I can get through a YT comment like this, that's about it.

    Trying to find somebody who knows how to deal with concussive brain injury in my city has proved impossible. I made contact with the medical research centre but all attempts to contact the brain injury people went unanswered.

    Reply

  54. I still dont understand the long term effects. He went on and on about there may be long term symptoms, but he did not actually say anything about what they are. GMBN you guys need to go back to your roots when your vids were to the point without this vague BS. This is so effing vague. What consequences? The content quality has been so vague this year.

    Reply

  55. I did half a front flip and landed on my head on a 6ft double and wearing a helmet protected me enough just to get a mild concussion.

    Reply

  56. Great stuff GMBN. Will you be following this up with some more info on how to recognise concussion and more importantly what to do if you think you have one? Maybe get EWS or Downhill medico/physio staff to give some tips on how they triage and treat and how the average punter can do something similar if their mate smacks their head. Helmets are awesome but they're only part of the story.

    Reply

  57. Completely agree and having had a few head injuries and concussion I always get the best helmets. But still have to ask why the best protective helmets still cost so much?
    I know all (most) helmets have to meet the same basic safety standards but why are companies, POC being one of the worst, charging so much to protect our heads when we have to replace the helmets every time we hit our heads.

  58. This is the story of how I got a concussion resulting in retrograde amnesia

    Me and my friends live in a small village out the back of a small town in nz and there are a few hills around us that we go and make trails and session there are Benches and tabletops big boulders logs and fast short tracks to ride all made up by our imagination one day it was just my brother and I out and I came down a hill that tooled on to the ones street in the village my front wheel got caught in the gutter this is coming off a 85 degree slope and I went otb landing on my head with lots of speed I mocked myself out for about 30 seconds than came to but I don't remember anything for thr 3 hours it took for the ambulance to come I had gathered the whole village there and thay where all looking after me I don't remember any of the 3 hours waiting or about 10 mi it's before the crash I am also a sailer and I wasent abel to do Eather sailing or mtb for 4 months and then only very coutiouly because of my conclusion the the respective rotrograde amnesia it gave me I'm all back now and shredding like I used to

  59. Michael Schumacher was wearing a helmet, but u all know what happened to him. Dangerous sports should be illegal, especially for kids. Or coaches should be forced to inform their students, that they might fuck up their brains if they do this kind of activity. They should teach this at school that the brain is the most fragile organ and u should take care of it. I personally received a blow to the head a year ago at a sport event and my symptoms don’t go away. I wish I was more aware of this topic before destroying my life….
