In 1998 I came off a Team Marin - hard. I still don't know exactly what happened, but I think I was following Ant too closely - a bad habit of mine - on a very very fast long downhill outside Brighton, above Rottingdean. These are baked-hard chalk runs with a scattering of gravel and huge flints. You need to be alert. I remember things from an hour before - passing group with the guy who broke his QR by over tightening it whilst replacing a wheel, the valley we dropped into with nothing moving and no one in it, and early morning breakfast - but then nothing....until late that evening. I have a flash of sitting on the ground looking across to Lewes, in the sun, with a collar bone protruding through a hole in my shoulder, and a flash of being stretchered into the ambulance. But that's it.
Eight hours of amnesia - and apparently being conscious but talking complete nonsense - and then lucidity returning when someone asked whether I wanted a cheese sandwich. 'Yes' I said - and the consultant said 'Ah, you're back....we were getting worried about you...'. She confirmed that I had a serious concussion, a 'moderate brain injury'. This I interpreted as good - 'moderate' is like 'moderate rain' which is fine for riding in. 'No' she said 'that's BAD'. Mild is OK-ish, Severe is gross impairment of function, 'moderate' means some thing lasting, but potentially not life-changing. I recovered, returning to work far too quickly, dealt with the headaches and fug, and was amused by my inability to recognise certain words - such as the incredibly challenging 'it' and 'they'. I recovered - or did I? Who knows, really. Most people THINK I am the same person so I probably am.
As a result I became interested in concussion, and read a lot of research and talked to a lot of medics. And from 2000-present the realisation has grown in sports that stuffing huge energy into your skull is a Very Bad Idea - particularly that which invokes rotational brain injury. Rotational brain injury occurs when the brain twists in the skull, and brain tissue is good at resisting perpendicular force (the anvil test of most helmets) and terrible at resisting shear forces, which just rips brain tissue apart (imagine a deck of cards - hold the pack vertically and bang them directly on the table, and the pack stays intact; hold them at 45 degrees and the pack shears apart).
Hence MIPS.
We were early adopters of helmets - mid 80s - the early Bells and Giros - just EPS with a lycra cover. And ignored the fools shouting at us from cars. Few people realise that the thin ABS cover now on helmets is to stop the helmets from grabbing as they hit the ground - that's what induces rotational injury. The plastic is designed to make the helmet skid on the ground. That day in Sussex, my helmet worked - the consultant said 'that helmet saved your life'.
I've upgraded constantly, not because helmets age - there's research which says that they don't, if kept out of endless direct sunlight - but to get better function. In 2019, due to the council putting down the wrong grit, I had a huge facial injury (along with 9 others in the city that evening) but the massive blow to the head was fine - the new Bontrager MIPS helmet really did its job. I wish that I had been wearing a full face, which I wear off road now all the time - my maxillo-facial surgeon said 'if you lose teeth again we won't be able to do much'. The nerve damage to my lip and face is defying prognosis and getting better month by month. Which is good. Without my high-performing helmet, it wouldn't have been that which I was worrying about, but something far more serious.
So....perhaps take the risk of concussion seriously, and ride a retro bike but a very very non-retro helmet. Yesterday we were riding single-track trails which we could never had ridden on retro machinery, and it felt safe and controlled. And I was sure happy I was wearing a full face with MIPS.
This is an interesting one:
