Good work Dave, needed said. I read a thing years ago written by a Shoei race technician demonstrating the importance of fit and how force is transfered across a gap, it was roughly:
"Stand up straight, with your lower arm perpendicular to your body. Make a fist and walk to a wall and once your fist is against the wall, punch as hard as you can. Now take a small step back and repeat. That's why you need a helmet to fit."
IMHO the plastic adjusters at the back of helmets are only there to keep costs down, you can buy a basic motorcycle helmet in 5 sizes, yet most cycle helmets are only available in a couple of sizes. Top end motorcycle helmets use multiple shell and lining sizes, cheap ones use one shell and 5+ linings on one shell, for the same sort of money as a mid market cycle helmet.
Maybe I missed it in the copy, but these products are on the same (UK) website. Normally I'd be a bit grumpy thinking this article was advertising, but they have quite a few things I've never seen before and I placed an order. Then there was a link in the order confirmation email to the owner, with their dog, saying thanks - nice touch. Happy Winterval!
Wool tights or 3/4's under the lightest weight summer shorts you can find. If it's actually waterproof enough to keep you dry you'll sweat them out and end up wet inside anyway. The wool will keep you warm when wet, I'll take warm and wet any day over wet and cold because nothing short of a rubber suit is actually waterproof. The light summer weight shorts shouldn't hold much water when they are soaked.
Unless you're just banging shuttle laps, then just take some cheap over pants and cut them off at the knees and pull them on overtop your regular riding gear.
I Googled "Wool Tights" and despie three hours of checking the results, still didn't find anything that I have the figure for. Have you any recommendations?
