I ride my bike indoors on the trainer for about two thirds of my total miles.  When I ride inside I sweat a lot, even though I ride with a monster fan trying to keep me cool.  All that sweat is a potential issue, when it comes to stopping corrosion of critical bikes parts.

A lot of sweat falls from my head and lands in the area of my front end and headset.  In order to try and stop the sweat getting into my headset, I have resorted to the set up in today’s photo.

Firstly, I use packaging shrink wrap, to surround the whole area around the stem and headset.  Then, I place a small towel over the top of the whole area.  Two years ago, when I first got my trainer, I just used a towel and it didn’t protect my upper headset bearing.  I had to replace it in the spring before riding outside. 

Hopefully, this set up has worked a little better.  I’ll be checking out the bearings, as part of the upgrade to my whole cockpit.  That process will start next week, so I will know the answer shortly.

I’m interested to know how others deal with sweat on the trainer.  Let me know in the comments section, if you have any good tips.
