can i ride a road bike on crushed stone?

Your legs as well if you happen to fall.

 

Pea gravel is just as bad.

 

You can ride a bike on any surface. I prefer really big stones. I did manage to rip a 2.5" tire completly off the front wheel of my Rocky last year, but I had a hell of a good time doing it!

 

That is why I tell the wife I have 3 bikes, thay are like tools, you nead the right bike for type of rideing you are going to do. I am still thinking about getting that single speed.

 

I had trouble finding "street" tires for my mtn. bike because of the 26" rims. had to settle for lightweight 1.5" tires.
My wife's bike has 35c tires on 700 rims. They're fine for streets, but would be a little skinny for trails. Maybe on a really well packed trail, but if I were trail riding I'd stick the 2.25" tires back on my bike.

 

I have 8, that's why I'm divorced.

 

Sure you would, get a bike that is fit properly for you and you should have no problem. Heck there are competitions out there for the MTB that are 100 miles. Set it up for you and ride like the wind.

 

The wife don't care about what I buy allmost any bike is cheeper than the race car.
I rode my Jamis Explorer 2.0 62 miles it has 26 x 1.95 tires I don't see what the problum is. I would ride the Quick 6 on a stone path and that has 700 c 38 tires. I think thear is more than 1 way to get down that path.

 

Sure you can, I've done it lots of times. Although it's not a hardcore mtn bike with rear suspension and all. It's a hardtail with lightweight hydroformed hardtail frame. Then modified with lighter tires.

I'd think the bigger decision would be wheather to get a bike with either 700 or 26" rims. There just aren't any off road tires available for 700 wheels. Plus a mtn bike has a better seating position for off road.
