I pinched flat this weekend going over RR tracks.
I am fairly new to road riding.
What's the trick?

Thanks!!!

It's not that much of a trick....biknben

Slow down. Get your butt up off the saddle. Bend and relax your knees and elbows to absorb the impact. Let the bike bounce around under you. Don't fight it.

Some times you really have to slow down if the tracks are bad. Tracks are also a common cause of crashes so people tend to slow down anyway.

If you're flying you could bunny hop over the tracks. Try that at your own risk.
How much pressure? Tire size? Weight? Should be easy. nmSpunout

I weigh 220 and had 110 on the rear and 105 on the front for the ride this weekend. This is only my 10th ride on the road and I have tried several different tire pressures.
I mountain bike 3 to 4 times a week and know the bunny hop, it's just the road bike seems so fragile compared to my Enduro!

at a comfortable pressure. Instead of running 120 psi, can you try 25 or even 28 mm tires? These are the widths the pros use in Paris Roubaix, for such reasons!

Or, 25mm tubulars.

You may want to check the size of your tubes. Too large of a tube for the tire will contribute to this problem.

I frequently hop the cattle guards on one of my local rides. I'm 210 now but I've hopped them when I've been around 225. It's not like clearing a log. If you have the speed you just need to barely get off the ground and float over them.

Actually, this is my second flat!retbchboy

My first one was on my first ride. I ran over some rocks that were washed out of a driveway. It's funny because in the back of my mind was the mountain bike mentality "See Rock, Go Over". I didn't even think to go around.
How do you know the correct combo of Tires/Tubes?

Thanks!!!
You're learning the hard way...biknben

Yeah, the MTB mentality may get you in a little trouble. Road bikes aren't "Fragile" but they are compared to a MTB. You can bunny hop, ride off a curb, and go over tracks, you just have to be more delicate. If you time it wrong, you'll be changing many more tubes.

The tire is the only means of suspension on a road bike, other than your body. As Spunout said, you may want to consider getting wider tires which will give you more room for error when dealing with debris and obstacles. At your weight and tire pressure, you can't afford to ride like a MTBer.

Don't sweat the tire/tube combos. The sizes of road tubes are similar to MTB tubes. One size fits "almost" all. The generic sized tube is 700c x 21-25c. I use them on my 28c commuter tires.
