I need to go redo some chains right now- infact, I rode today and was thinking about needing to get out the crockpot!
That said, I have only felt one drawback with the waxing- rain. If things get wet, about a week or so later things go squeaky. Not a bad thing, but, something I need to stay on top of.
Recently, I took a bike on a century, got rained/poured on, needed to take it out again, but it was needing some attention so I just tri-flowed it to get to the ride, but it made a mess and now I need to clean it all back off to get back to the waxed way of life.
The "triflow mess" meaning how I got through the first 40 years of my biking life.
Somebody even noticed the dirty drivetrain and commented- which was odd b/c I'm about the only one who goes through the trouble of waxing my goods!
I was thinking "Why are you singling me out? I usually have the cleanest drivetrains here, and in a world going to hell in a handbasket, why notice my triflow?"
In my current setup, a desnap the chain, fill a "7-11 big gulp cup" full of kerosene, drop in the chain in the 7--1 cup into the ultrasonic of dirty kerosene (good for the chainrings) and let it clean. It's about down to a science, and takes little time at all. The longest time is letting the chain cool down before I can grab it to reinstall without burning myself!
