How much glass don't we see?

We've all tried steering through/around a patch of broken glass to spare our precious tires. But
we only see what's reflecting sunlight at the time. How many shards that we don't see are we
riding through? Has anyone ever done a study or analysis? How wide a berth does prudence dictate a
rider take?

(Personally, I ride on "tank treads," slime tubes AND kevlar liners. I think the tread will wear out
before I have to replace a tube. [Probably just jinxed myself.] They've lasted 1200 miles so far,
and as long as I stay away from stopwatches, they're fast enough for me.)

I've ridden over 2,700 miles on my Micheli Axial Carbon/Victtoria Rubino Kevlar combo so far.

I have over 5000 miles on my Performance K2 700 x 23 tires (bought for $8 each) with no flats and
plenty of tread left. I've raced on tires costing $50 per and these cheapies and can't see a
difference other than the more you pay the less they last :-(

I usually get about two flats in the 4000 mile life of my Hutchinsons (Profile U w/kevlar).

But then I'm conscientious enough to avoid what I can, and brush the tires with a gloved hand to
catch what I couldn't.

May you have the wind at your back. And a really low gear for the hills! Chris

What's the big deal with an occasional flat?

I ride 26mm "racing tires" and suffer infrequent flats. The trick is to ride where the cars drive.
There, your likeliness of encountering sparkles is miniscule.

I'll second that, expensive tyres are nice for racing but pick up little pieces of stone and glass
like sticky tape on training rides.

You ride your bike on the highway?

I've been trying to do that also, but I'm having problems with the rear tire. How do you do it
without falling off or getting your hand caught in the brakes ;(

Front tire is of course easy.

Inconvenience, and frankly I change tires so infrequently that I'm not entirely sure I remember all
the little tricks to doing it right.(!)

I love being able to take the bike off the wall, ride it, hang it back up, and think about
maintaining it eventually. I get around to the maintenance part at least once a season. It's a great
bike (2002 Lemond Tourmalet).

Because *if* there's something on there that's loose enough to brush off, you've got 50% chance of
banging it in instead of taking it out, and 50% chance of having it pierce your gloves and making
you remember when you last got tetanus shots. Especially glass shards go through gloves like a hot
knife through oil.

I loop my thumb around the seatstay, then lower hand until gloved palm contacts the tire.

Really ? I have never seen a case of that. Have you done it?

I once saw a guy using his index fingertip to keep his front tire clean. Couldn't decide whether he
was tough or stupid.

In addition to my last response (it has not effect), you also create a risk to yourself. This is
especially important for newbies to not learn as it creates hazard with no good result.

More directly, because it has no effect on incidence of punctures, as indicated by my God (and don't
think I'm kidding) Brandt.
