Flat Tire Pollen
I picked this up with a 2-inch magnet on a 750-foot traverse over a shoulder I ride frequently.


Posted 45 mph.
I couldn't see any of this walking, much less riding.
I'm now amazed I don't flat much more often than I do.

Where do you ride?
Much construction in our area. Things falling off of trucks.

Ha! Nobody drives 45mph on that stretch I bet! Around here anyway, a road like that would commonly be driven 55-60mph, regardless of posted limit. Do you think speed has something to do with wire bits and other magnetic debris on the road? I guess it makes sense that greater forces would knock more stuff loose, but I’ve never thought about that kind of thing before.

I don’t think speed has any relation to debris accumulation.
Probably biggest factor is slope to wash off debris in heavier rain.

Bikes: too many sparkly Italians, some sweet Americans and a couple interesting Japanese
Very common steel belting from steel belted tires. Most roads are only crowned at 2% so it takes a good rain to wash the fragments off. Our retirement community runs street sweepers often and has lower speed limits and it really helps compared to the city/county roads.
