How To Stop Pinch Flats

Use thicker tubes. I think it's Kenda that make nice thick ones. Try to land a bit softer too! Since I cut half the tread off of each side of my Maxxis, I've been getting pinches all the time, although I run stupidly low pressures, like 12psi or something...

Get the Kenda tube. http://www.tartybikes.co.uk/product.php?pr...;category_id=32

I was in the same boat as you. Gapping and landing on the edge very rough and getting pinch flats.

The Kenda tube is MASSIVE, haha. And so strong. I did a gap to a metal railway line from a wall and landed so rough a dented my rim, but I didn't puncture.:)

Saying that though, I have punctured it 3 times since i've had it. But I am very ruff. :P

actually its not just how smooth you are. four things effect this bike wise...

-tire

-tube

-rim

-psi (of course)

First off running a wider rear rim reduces pinch flats dramatically. consider using the onza 128H rim its the widest rim out there, you will be surprised a couple mm goes a long way

second off for tire its been my experience that every product ever made by monty is defective though I never used the monty tire its lighter than every other type by a lot, my creepy crawler was about 3 to 4 times more puncture resistant than my echo tire. The material, and thickness, and stiffness of the tire effects it a lot.

third consider cheng shin tubes or a medium weight tube. They are only 50 grams heavier than a regular tube but about 2X more puncture resistant, while the super heavy duty tubes aren't much more puncture resistant than a mediunm weight tube but dramatically heavier.

Rider wise...

-you could loose body mass this is the only one I could recommend if you are heavy because usually you can loose mass and maintain the same strength to weight ratio you have.

-you could be smooth all the time (worst solution in my opinion as it restricts your progression dramatically and limits the things you can try)

-you can do more calculated gaps. Example a 7 foot gap onto a round rock won't pop your tire so you can hit it rough, but a landing onto a sharp corner like a 90 degree street ledge will.

In my opinion do the bike solutions, you shouldn't have to not try stuff just cause your afraid of damaging your bike. Once you can't progress your riding any more worry about getting smooth and more or less nobody stops progressing even pros.

Good post. Was very imformative. But surely that can't be truee. ^^^

The heavy duty ones must be a bit stronger or else they wouldn't make them?

well what I find is for most anything a medium weight tube works, the only way they pop is if you bottom out the tire so hard to the point where you are denting the rim, but in this case dh tubes even pop sometimes, so I think medium weight are usually good enough.
