Hello Commuter Forum,

Newb here with a few questions.

I haven’t done any riding other than leisurely short rides around the neighborhood with the wife and kids (7 and 9) on and old mountain bike.

I have an old Trek 2120 that’s been sitting around unused in the back yard for 15+ years. My work has bike tuners onsite once a month so I brought it in for some tuning. After a 6 mile cruise, I decided I could ride it to work.

On Sunday I rode the route. Now I’m planning to start riding in to work a few times per week. One-way is 16 miles. 3.6 miles of that is dirt/packed gravel.

Tires are 700 x 25mm Continental Grand Prix inflated to 95PSI front and back. With clothes and back-pack I’ll be riding around ~170lb.

Will these tires be OK on the dirt/gravel portion?

Should I carry a spare tube, or a patch kit?



Thanks in advance,
