Here on Oahu we have lots of paved concrete highways. Maybe its just me but the bike always feels twitchy on concrete in turns. Do concrete roads offer less traction than asphalt?

It's probably the "lines" in the concrete that makes the bike feel twitchy. They use a huge machine to grind the concrete smooth but it leaves vertical lines that play hell with a bike. You get used to it after awhile.

not only does it feel twitchy but it also feels like theres less traction on concrete.

Well that's because there is less traction. You're actually riding on a series of parallel ridges. Ever ridin across a corregated steel bridge? :icon_lol:
Yes, I avoid it now. scary for me.

Makes my tires feel like they're floating across the road when I hit those concrete sections of our freeways. Scared the hell out of me the first time I got back on my bike after going down because of a flat tire. Same EXACT feeling from the tires.

also, before I get flamed... I hit a patch of nails and it punctured BOTH tires as well as 40-50 other cars because a construction truck dropped a box of them out the back.

concrete DOES in fact have less traction (coefficient of friction) than asphalt. I stay away from leaning too far on concrete roads.

same as wet asphalt

I was told in my MSF class that dry concrete had about the same traction as wet asphalt...not sure how accurate that is but concrete does have less traction than asphalt.

I thought the grooves in concrete were put there on purpose so that when it does rain it gives more traction. I would not want to ride on wet, smooth concrete

kakashi74, that is correct.

The grooves in concrete act just as the grooves in your tires in the wet; both help to channel water away from the contact surface. This is why slicks are not prefered in the rain. Also, I do not believe that concrete is as porous as asphalt, so without the grooves you would experience more pooling of water on the surface.
