Helmet Shapes

Now they're all spiral flourescent ones, because the power company pays to keep them cheap so we don't need another nuclear reactor, due to the energy savings over incandescents.

Lethal though. Mercury in them

so that whats wrong with me,my grandad had a big jar of mercury when we were wee boys and we used to play with it,we called it quick silver

So are older tooth fillings, an amalgalm of silver and mercury, IIRC

How often do you have to replace an old tooth filling with another of the same type though?

There is also a recycling effort for these bulbs, so the chemicals and elements stay in the process. Most home centers recycle the CFL bulbs.

... and the saddest thing is that these passed far stricter testing and offered more protection than any on the market today

And I think I still have one in my garage. And an Avenir from the same era in the basement.

you mean you have got electric bulbs,now theres an idea

What is this electrickery that you speak of? ( Courtesy of Catweazle!)

Light, without candles, yet having candle power.

I guess I buck the trend then. Still using my Bell MTB helmet complete with peak/visor when out on the road bike. It might not look pro, but it's a good lid and I can't imagine I'd get any really appreciable value, with the type of riding I do, if I spent a load of money on an aero helmet.

 

[Racing roadkill]

I spend lots of money on lids. I've got a Casco Warp Sprint, and a Casco speed time, at present. The speed time is very cleverly designed, it's about as aerodynamic as it gets, weighs less than an empty crisp packet, the advantage is most noticeable on a fast descent. The reduction in buffeting is noticeable, as is the fact your eyes don't water, and you don't have the annoyance of glasses slipping down your nose, every time you hit a bump in the road.

 

[Rob3rt]

I very much doubt the Casco Speedtime is anywhere near "as aerodynamic as it gets". For a start it is a stubby helmet, stubby helmets are not as fast as proper full blown teardrop helmets on the vast majority of riders. Stubby helmets are good at accommodating a wide range of rider positions adequately (but not optimally) and for events where you will be looking around a lot, which is certainly not true of a time trial (the discipline for which that helmet is intended) where you head will be in the same place for the duration of the race bar the turn or a couple of corners.

Found this in the loft.think it's from late 80s or early 90s

 

[bpsmith]

That's pretty cool with today's standards in fairness!

 

[tyred]

Never bettered.

Is there less wind noise with an aero helmet?
