Maybe I'm lucky in that I can store my bike inside an unused office or storage area and there's no problem with my stuff disappearing, but I just hang my damp clothes on my bike to air out. No noticeable odor when everything's dry but a quick spray of Fabrize would work too.

Wow, lot's of great advice. Nice to know I'm not the first to run into the issue and that there are a lot of creative solutions. I like the camping towel idea. Looks like I'm headed to REI and will be doing a lot more laundry until I can add to my cycling wardrobe.

Thanks for all the great responses.

Would it be possible to hang your clothes in the shower area?
We have a changing area in the shower areas where some hang their stuff for commuting or lunch workouts. It even has a closet rod or two.
We also have lockers.

If you have as little as a desk - then folding laundry rack under the desk will do.

If you have nothing but a locker, put a clean change into a Ziploc bag and damp morning clothes into another bag, and wash both at night. In case you live in a humid climate and shammy does not dry overnight you will need another two changes. Every once in a while give your cycling clothes a nice soak in Oxy-Clean to guard against stink and rinse thoroughly. Stuff is high pH and will be pretty hostile to a sweaty skin.

The OP linked "sweaty cycling clothes" with two issues: a) "stinking up the office" and b) getting them dry for the return trip.

Stink should NOT be a problem if you are starting with clean clothes and a clean body. A little clean sweat, while maybe gross to your office mates, is not going to create a stink. If you start all nice and hygienic, you should be able to hang your stuff up to dry without worrying about the stink. And being able to hang stuff up to dry solves problem b).

If stink is a problem on the hanger, it's probably a problem before you get on your bike.

In summer months when you can't avoid sweating, you should be OK to just hang and dry those wet but not-necessarily stinky clothes. I think carrying a second set of clothes and hermetically sealing your sweat-damp but otherwise clean clothing is overkill. You only need to find a spot where your damp stuff isn't going to freak someone out visually. I've worked in a couple of different configurations from office to cube land and always managed to find a little niche out of people's way but with some air circulation. That's all you need.

I have bigger problems in winter and rainy days. You can and should dress to avoid overheating, so sweat / stink should be less of an issue. But you just have a lot more kit (in most locales), so more stuff to hang.

Make friend with the janitors or housekeepers or whatsoever you call them in youe office. These people always have access to some spare space where you can hang your clothes to dry.
