Peter' reply to newsgroup only said:I am a 79 year old senior citizen, but I am still able to ride my almost 50
year old three-speed "Made in England" bicycle.However I have been unable to find a bicycle helmet that is held onto one's
head without the strap under the chin. Unfortunately at my age that strap
is not tolerable for me.Hence I wonder if anyone in this group might have some suggestions for a
bicycle helmet that can safely be used without the use of chin straps.
You don't mention if you still have hair or not. If not, I suggest
purchasing some rubber glue from a carpet store. This will hold the
helmet quite firmly and is surprisingly comfortable. (I was going to
recomend using tubasi, but as you describe your bike as a "made in
England" three speed, I assume you are using clinchers.)
If you still have a full head of hair don't worry, all is not lost.
Screws designed for particle board will work great. The trick is to
first drill a properly sized pilot hole (not too deep!) and to file
the points off the screws to avoid piercing the dura. I have had
problems with the steel or plated screws rusting. Stainless is really
the way to go, especialy if you ride a lot. Unfortunately, stainless
steel particle board screws can be hard to find. A workable
compromise may be to use ordinary stainless capscrews, as these are
redily available in bike shops. I do, however, have my doubts as to
how well these would hold in a crash.
Done properly, screws can be as comfortable and durable as the carpet
glue, and some even claim additional benefits:

But I feel the evidence for this is lacking.
