TE/TC dumb question but i have to ask

The new rear subframe that's made from plastic how strong is it?

I'm a 300lb rider?

What if the rider puts his kid or chick on the back and go for a little ride?

Now modern plastics have a life expectancy??

Example, the new plastic pistols of today have a fourty year life expectancy. But there not in the elements.

What's the safety factor or is it just enough to get by?

Can I get a steel subframe replacement?

You won't have any trouble with the subframe, I had a good crash already where the side and subframe took a good pounding. No cracks or bending it all just springs back. If it had been aluminum or steel I'd be buying a new subframe.

I've got 62 hours on mine and I am 220. It's really a composite, not plastic. It is tough stuff.

The only way you could get a steel replacement is if you made it. I wouldn't sweat it at all. Like LandofMotards said, pros pound these thing WAY harder than we do.

Holds my 250 lbs of geared up fat arse for over 60 hours. No signs of weakness so far.
