Armour - Spine and body?

[Winston001]

Any advice about armour to protect the whole spine as well as the body for general road riding?

I'm sitting here with a fractured C4 vertebrae and wondering what would have helped prevent it. I'm a very very lucky man.

[R1madness]

yep thats a nasty 1. unfortunately noone really uses good quality back protectors on the road even tho there ar lots to choose from. the best i have used was the dianese body armour mesh suit. went under your jacket and was a little like mx body armour but made for the road. i think i am goin to save up 4 a airbag vest sort of like they use in motogp only a bit bigger lol.

[aahsv]

Check out the Alpinestars Track Vest or the Sidi Defender - both have combined chest and spine armour - very comfortable under leathers.:2thumbsup

The C4 thingy sounds like a lot of disscomfort.

Hope you put that behind you asap.

I have looked at the back protector thing myself. I thing it has to be a question of just how far you are going to go. The big hump on your back thing is a bit OTT for general road riding however you never can be too safe.

If you feel that the type of riding you do makes coming off quite probable,
then you need to go as over the top with protection as possible.

You need to somehow find a balance between safety and practicality.

There is no "big hump" with a back protector I use my Spool back protector any time I ride on the road

[p.dath]

I got a back protector for use at AMCC track days. Since I have one I now use it anytime I know I am travelling on 100km/h roads. I don't bother on 50km/h roads.

I'm not sure that back protectors add so much protection at lower speeds.

I guess there are too things to consider.
It will provide abrasion resistance if you end up sliding on your back, and are wearing a two piece, and that two piece separates (common if they don't zip together).
If will provide some impact protection if while sliding you hit something, like a curb, or perhaps something it sticky out of the ground like a stick. Obviously it only protects against impacts to your back.

So I guess consider what kind of accident you want to protect against, and then get gear that will help stop it.

Gear wont stop an accident you silly man.

Dear Dainese/Santa,

For Xmas this year I would like gear that protects me from the kind of accident that would kill me, or leave me with a permanent disability.


Thank you.

[vifferman]

I'm not sure that back protectors add so much protection at lower speeds.
What?
That is to say, WTF?!?!

I've never crashed on the open road. My last crash (car u-turned into me), I bounced off the car onto my back, and was VERY glad of the built-in back protector in my jacket (not one of those thin foam pads, but a reasonably substantial moulded item). My back hurt, but was not even bruised.
Oh wait - I was imagining that it protected me; I was not actually going fast enough for it to do any good. Perhaps the built-in speed sensor was faulty. :rolleyes:

My current jacket doesn't have a decent back protector, but I do have a Teknic back protector in the cupboard. I don't wear it while commuting because I think it would be over the top, which is errant nonsense. I guarantee that most crashes happen around town, due to the sheer number of vehicles and the appalling standard of driving. If you crash on the open road, most times it will be due to pushing it too hard for the conditions or an incident such as crap on the road.

As for back protectors being bulky, mine is not one of the new slim-fit jobbies, but one of the jointed armadillo types, yet even though my jacket is pretty snug fitting, the back protector fits under it comfortably, and is barely noticeable. I'd like to get one of the newer ones, partly because they're a better more unobtrusive design, but also because they protect more of the spine. Mine stops before the top of my shoulders and doesn't extend down over the coccyx region, unlike most/many of the newer types.

[Sidewinder]

a hump isnt a back protecter lol. alpinestars do a mean back prtecter

[enzedone]

So are any of these o.k or a complete waste of money then?

That makes it much easier when selecting gear then. Because your not concerned with low speed slides, loosing chunks of flesh (abrasion protection), or minor breaks to bones.

LOL.

[p.dath]

Gear wont stop an accident you silly man.

Increasing your visibility may prevent (or stop) an accident. But granted, gear is normally used to reduce the seriousness of injuries.

Looks good. My only reservation is I've read that mountain-bike and motocross armour aren't up to highway protection. Still, worth considering.

Its hard to protect against every possible accident but it strikes me as a useful exercise to discuss optimum protection. I haven't described my own accident here yet because I'm concious members bin every day and I'm no-one special.

For the record, I have no memory of the event. My helmet and leathers indicate sliding on my face across bitumen and then gravel. This involved major impact to my head transmitted to the upper spine, and then translated across both shoulders. Spinal compression but thankfully insufficent shearing and swelling to hurt the spinal cord. Bit of nerve damage to my left side. Fractured C4 vertebral process which is healing. Concussion and head injury. Effectively lost a week of my life. :D

So. If I had armour which prevented compression of the top of the spine, and spread that force elsewhere, I'd be a much happier chap.

What do F1 racers wear? They walk away from horrendous accidents.

[enzedone]

Thanks for this information.

I'm not talking about a 'controlled' environment where your 'sliding' off around a corner or something onto nicely prepared 'hotmix'
I'm worried about exactly what happened to you, flying over a bonnet onto sharp/hard bitumen. Totally different situation. I am NOT a bike racer. I have not had experience 'falling' correctly.
I need to be sure that in a situation which will be a surprise and I will not have time be thinking about 'how' to land, my gear will be there to at least help with the impact.
This is why I will not buy a jacket before I have decided to go with some sort of body suit or not.

Personally I dont think the body suit is the way to go, reason its bulky and hot, and they arent made to go under a Jacket.
Most reputable jackets have good armour systems in them, ie Shoulder and elbow, combine this with a good brand back protector (not a non tested cheap one off TM) and you are all good, good idea is a chest protector as well

http://www.quasimoto.co.nz/products/knox-body-armor/knox-chest-guard

For me I wear this combo and I have crashed in it 4 times, so far all good.

Remember tho that whatever jacket you get go up a size from your actual chest to allow for this gear ok, other wise it will be to tight.

You can protect yourself so much thats all you can do, rest is up to the crash dynamic.

good luck

And as posted already, my Chest Protector: http://www.quasimoto.co.nz/products/knox-body-armor/knox-chest-guard

Used for all country rides... and awesome stuff. Chest protector has even doubled as a bird deflector! I've had several birds hit me on the chest, closing speeds above 100kph, and I barely feel a thing.

Went for a slide on my chest earlier this year... not one bruise or sensitive spot.

Once everyone gets used to having back protectors, we'll need to get them used to chest protectors. :2thumbsup

Lucky for them they are in cars, so they wear a carbon-monocoque chassis with a survival cell, well-fitting seat, 6-point harness, HANS device and a Helmet.

Unlucky for us thatd be pretty much impossible to incorporate into bike gear, but i do think a back protector sounds like a good idea! I should definitely get one :D

Dammmmmmm sidewinder, I'm not that way inclined, but you look gooooooood brother. Have you been using one of them ab pro thing dingy's

Do you get the red pen with the unit or do you have to buy that separately? from a specialist sports equipment shop or something.......;)

My mother in-laws got some of those pants too, do you know her...:whistle:

Quite frankly, I don't see that given the type of impact you had, that you'll find anything to prevent injury of that sort. However, you'd be REALLY unfortunate to strike that again.
If I were you, I'd just get something of the kind that Quasi sells, making sure that it gives you protection from as high up and low down your spine as possible, and add a chest protector if you want protection from frontal impacts as well. AFAIK, there's nothing (apart from a good helmet) that protects from compression injuries of the kind you were subject to.

Apparently though, there's an auto-inflating neck brace for motorcyclists currently under development, that should help a lot with preventing neck and upper spinal injuries by reducing skull rotation.

Yeah, I know that. I was talking about the thing that was posted on here (?) a few weeks ago, that deploys to support the neck and stop over-extension of the neck due to the skull moving around.
Looked like a blardy good idea to me, and unlike the jacket would be fairly reasonably priced.

[Winston001]

I was wearing a 4yr old FFM flip-up (el cheapo) and so far as I can tell it saved my life. The lower lip ripped off at some point but despite sliding on my face (lots of gouges on the left front of the helmet) the only facial injury was a minor gash to my chin. Few stitches and it is completely healed now 2 1/2 weeks later.

The real damage was caused initially by compression of my neck, and then I suspect, extension of the neck as the head was forced forward under my body. Must ask the surgeon what he thinks. Was too full of happy juice and euphoria at not being paralysed to delve into matters with him. :2thumbsup:2thumbsup

A miracle really. What surprised me was the surgical guys brushed aside the fractured vertebrae as incidental. Their point was if enough force was imposed on the cervical spine to break bone, where did that force go and what did it do to the spinal cord? Enter the MRI - which is a tale for another day.

The conclusion was a little cord damage - hence hypersensitivity in both forearms, plus extreme stretching of tendons and nerve root paths across shoulders to the arms. My upper back and cervical spine are still very tender and I'm in a philadephia collar for 6 weeks. A small price to pay. :D

[MaxCannon]

Paid $100 for my Tecknic back protector and use it whenever I ride.
It's basic model and I'll be looking to grab a Knox one from Quasi soon (along with the chest protector)

It takes 5 seconds to put on and could be the difference between walking away from a crash and being carried away.

I'm so used to wearing it these days that if I'm not wearing it I feel like I'm naked.
Both my jackets have built in back protectors but neither extend down to the tailbone.

I've never crashed my motorbike but have come off road / mountain bikes several times. Tarmac is bloody solid stuff.

I've got a KBC head aswell, I've been using my old ARC helmet for the past week while the KBC was being disassembled and cleaned. The ARC is shithouse, the KBC fits like a glove, I've tried on Sharks/Arai's/ridden with a shoei and owned/binned in a HJC and nothing comes close to the KBC (VR2). I think its more of the fitment around the jaw than the head that nudges it ahead of the rest. Do you find the same thing Maha?

[Dean]

I just bought me a nice back protector and a kidney belt, awesome stuff :).
Next is leather pants w/t kneesliders, sidi boots.

I have two, only used the new one a couple of times which is alot snugger (is that even a word?) but I always grab the one thats coming up five years old. But yes, the new one, I can feel the difference around the jaw and check area. KBC aint the dearest or the cheapest, they seems just right.

[Anakist]

I fractured L2 - L5 sliding into a light post a couple of years ago. Bike slid unobstructed and stopped maybe 1m past my light post. Pretty fucking low speed impact I would guess.

I have been looking for back protection since, the only one I have found to be CE level 2 approved is the T-Pro L2 by Forcefield. I am currently trying to buy one. It is 99 GBP (188 or so AUD), or about $300AUD locally.

Eeerrr um....if I could go on topic for a moment, my question is whether there is any armour which protects a riders head and cervical (upper) spine in an accident. Both James II and I have landed on our heads. It can't be uncommon when you consider a riders head is the highest point on a bike and the torque of a bin will throw the body headfirst at whatever is available.

The collar airbag sounds good, if high tech. I notice mountain bikers can buy collars but they wear very insubstantial helmets compared with motorcyclists.

[Reckless]

I was thinking about this when you first posted Winston.
Sounds like you need a Leat or an EVS neck brace like we use on the trails.
Stops compression and whiplash!
I think some of the racers use them as well??

I have an EVS for Moto X and trail rides and use it constantly!

There may be others the road racers know about?? Do a Google there plenty of vids on them on the net.
Dunno if its what your after but Hope it helps??

PS if you go this way best to try on with your gear as they may not fit to well with leathers.
I'd expect the more expensive Leat Prob would be better for road??

I am always surprised at the twats who wear back protectors and back packs, presumably on the assumption that one will negate the other?

[Geemsee]

Always wear a back protector, bigger the better really as long as you can get it under your leathers! The one day I didn't wear mine 'just nipping out for a bit etc' yep you guessed it big get off, broken pelvis (by the cockix .. spelling?!) not sure if it would've helped all that much there BUT always wondered what if!?

[Hitcher]

You mean "back packs ......or......Back Protectors?

Both. I think that the wearing of back packs (i.e. luggage attached to one's person) is dangerous and possibly a practice worthy of banning.

I think that back protectors are probably a good idea for those feel like wearing them.

I think that wearing the two at the same time is completely strange: a desire to protect one's back in one breath, combined with a desire to break one's neck in the other. Either a rider wants to protect their health or potentially destroy it. What I struggle with is an apparent wish to achieve both goals simultaneously.

As a rule there aren't any trees around F1 tracks. Also they are heaps fitter then thee or me (and they are lots lighter than me!).

Their cars have crumple zones designed to absorb much of the initial contact. Didn't help Ayrton Senna though.

Is it the impact resistance or abrasion resistance that you think is adversely affected? I'm guessing impact?

Is it that your concerned about someone coming off, sliding on their back, and then hitting something with their back and having the backpack contents rammed into their back?

[grotto]

I often wear a back pack with my wet weather gear in it.
I can't see it doing any damage, and thought it would be some extra padding over and above my back protector.

Maybe I'm wrong?

I'm sure Hitcher will be along shortly but in the meantime, my mental picture is of a rider landing on his back which immediately twists and bends unnaturally because of the attached pack.

At the risk of irritating some easily offended members because I have dared to express a personal opinion, I think that landing hard on a backpack has a significant whiplash risk. A helmet adds at least 1.4kg to its wearer's head. That exacerbates moments of inertia which could see a broken neck, in addition to the spinal cord generally being bent the wrong way as it's stretched across the pack beneath.

Additional stresses and strains could come from the pack moving around, exerting leverage on shoulder joints, collarbones and arms generally by means of the shoulder straps.

And ATGATTers should realise that a backpack obscures any implied benefits from their fluoro vests.

I understand why some riders use backpacks, just as I understand why some people ride in shorts.

[Quasievil]

The Crash Dynamic is variable ATGATT is the winner on the day.

A backpack can......dependant on the crash dynamic, cause you to roll, ie the pack can turn an easy slide into a high speed roll (not good). Also what ever is in the back pack can cause an issue to, unfavourable, or dependant on the crash dynamic favourable........fuck who can tell.

But I see people putting cellphones and keys into there jacket pockets, dependant on the crash dynamic this can be a problem to.....but again who can tell.

Get the best you can afford and do yourself the favour and wear it.

there are a billion + situations in a crash dynamic, you cannot prepare for them all...........alot is about luck

I bought a really tiny phone and a really skinny wallet for just these reasons.

My phone makes phone calls. It doesn't do any of the other useless shite modern phones do.

Buy Quasi's gear Winston. I'll vouch for it (you've seen me wear it)
