A few years back I put some Kenda Kwicks on my old Peugeot PN-10 so I would not have to pump up the tires so often for a 10 minute ride from the train to my office. Last weekend, I put the tires back on and went for a very light cross ride. Fire roads and non-technical singletrack. There is not a lot of clearance for the tires so mud rides are out of the question, but my question is...is this safe?

The frame/fork is one of the old Vitus 780 steel noodles. Am I going to kill myself on this? How safe is it to ride a converted road bike on light fireroads and non-technical singletrack. No rocks, no jumping, no high speed downhills.

Here is a picture, please disregard the mess in our garage:>



Thanks in advance!
