Steel plates are slippery when wet(7 posts)

I had to ride over some steel plates at a road construction site last night. Some very light rain (mist really) made them wet. I know they are slippery (I've spun my car's wheels on them) but on my bike it was worse than ice. Basically, I won't try to do anything but coast over these things again in similar circumstances.

Fortunately I wasn't turning--I am afraid that any lateral g's would end badly.

I was crossing a wooden bridge which terminates with about 6" of flat steel as a transition to concrete and starts directly into a tight right turn. It was raining real rain here in NM and I swear I was being careful, but the rear kicked out instantly and I knew I was going down hard. In those darn milliseconds of clarity (apparently my allotment) I even knew what my palms were gonna look like when it was all over. But then a miracle as the tire grabbed traction on concrete and righted the bike just as quickly (Pro Race).

So a little gracious reminder that wet steel is every bit as slippery as ice was welcome. I'm hoping that I won't have to re-learn each year on that happy day when it rains.
so are groves in concrete, railroad tracks, painted lines..nmcyclopathic

I know exactly what you're talking about with the metal plates as the streets in my town are constantly torn up. Some other stuff that will get you sideways on the bike.

- Wet leaves
- Smooth tar coat style pavement after a good rain (common on many MTU around here)
- Manholes

All of these are features of my daily commute. I just keep the bike pointed straight and don't corner as sharply as I did during the summer months.

Two weeks ago I was riding around my usual route when all of a sudded I was cought by some pretty heavy rain. On the way back there is this road that has several pedestrian crossings that are decorated by cobblestones across the entire crossing. There is one of them in particular that is about three times as wide. I had never passed over them when wet so I just blasted accross as usual. All of a sudden I felt a tatal loos of traction and the rear wheel just slid to the left hard. It felt like the bike was going to do a full 180. The rear must have swept about 45 degrees when I got that feeling that only takes a millisecond but actually feels like an eternity when you say to yourself, you know what I'm going down hard and there's nothing I can do about it. Fortunately immediately after the tires touched the pavement again and straightened enough that I was able to get back in control.
