Is it safe to wear a helmet without a plastic covering?

One thing the plastic is designed to do (and for which it doesn't need to be thick) is to have low friction with the road. So if you come off your head slides rather than snagging. The friction that ...

Simply, I reject the premise of your question and I'm sure I'm not alone. I say that as someone who has a tourer and a hybrid, and commutes on both - the speed difference is much less than the ...

I have a 2nd broken spoke after 300km on a new bike, is it the wheel or me?
