Gawd you guys take the biscuit. I have repeated the same thing a number of times and people still like to totally distort it to fit their own stupid prejudices..
simply put – a cycle FF helmet has no poly to absorb impact in the front – so does not offer protection against serious frontal impacts and the sticky out chinbar provides leverage which can create rotational forces in an oblique impact which can cause both spinal injuries and diffuse axon injuries. Teh weight is also significant in wiplash type spinal injuries
all this is proven fact. Poc helmets for example are desigend to reduce rotational forces
With a cycle FF helmet you are reducing the chances of a sore / damaged face, possibly reducing the energy of a serious impact slightly and increasing your chances of spinal injury and diffuse axon injury
Quantifying any of these altered risks is impossible with current knowledge.
As for the brakes – the theory and that is all it is is that if you use bigger rotors than you need the bakes never get into the working temp range so you get excessive wear – a theory based on a lot of research.
You see – unlike many on here I like to follow the science not anecdote and surmise and guesswork. Everything I have said here is backed bey real peer reviewed research
Of course – as it goes against the orthodoxy I will be shouted down as a heretic.
