Hi--I'm usually browsing the Road Bike forum but am here to ask for some advice.

I'm finally considering commuting to school; it's a University and is 7 miles away and takes me around 26 minutes.

I want to commute in my (spandex) cycling shorts/bibs with chamois, then change into regular clothing to go to class which is about an hour and 20 minutes. Then I commute back.

My question is; is it safe to commute in my cycling shorts, let them hang in the locker, go to class for an hour & 20 minutes, change back into the shorts, and finally ride back?

I've heard reusing shorts can cause saddle sores and other unwanted business down there, so that is my main concern.

But here are some things to consider:

- I will shower (at home) before every commute.
- My commute time to school will be at 11:00 AM and I will commute home at 1:30PM
- I live in San Francisco where most days are around 57 degrees to low 60s
- The ride TO school is favorable; tailwind and mostly downhill
- I can use the locker room to rinse off after commuting there.

And finally, I do not sweat like a pig. In fact I may be able to ride to school with minimal to no sweating.

I just want to be safe though, and would love to hear from people who commute with their spandex too, and how they go about changing.

Thank you in advanced.

Edit: I forgot to mention that I want to be in my cycling gear so that on my way home I could just drop off my bags and continue on riding.
