It's that wonderful time of year every cyclist loves...shorter, colder, wet days...winter. Otherwise known as trainer season. We know "everyone" is getting a Peloton this year, but some folks still suffer inside on the traditional trainer. Fortunately, trainers have come a long way and programs like Zwift make it a more interactive experience than binge watching Breaking Bad, again.
There is one thing that will never change, and that is you sweating all over your bike. So, what's the big deal? You sweat in the summer riding outside, what's the difference? When you're just sitting over your bike stationary there is no wind to effectively disperse where all those droplets go (generally onto the poor person in your slipstream). Without wind, gravity takes over and drops all that hard work onto your bike slithering its way into all the nooks and crannies corroding bolts, aluminum handlebars & seat posts, and potentially into your bottom bracket. Check out this article from Zwift for more details.
There are a few things you can do to help prevent damage to your bike and make riding your trainer a little less awful. Set up a fan or two in front of you to simulate the wind from riding outside and put a towel or cloth over your handlebars and top tube. Enter the Sweat Net from Blackburn. For $15 you get a pad that Velcros to your handlebars and top tube, making it easy to put on and take off to wash after each session, and you don't have a towel hanging around your legs getting in the way. We have them in the shop, pick one up and save your stem bolts and headset. Even if you use a carbon frame there are still bolts that can corrode.
