Have not tried them, but I've had lowers years ago on a larger bike. I did not like them. Too damn hot due to lack of air flow. Plus, I'll be honest, I looked at the Madstad page just now and I didn't like the look. IMO the T120 just doesn't lend itself to lowers, but that's just me. Madstad screens look nice and I have thought about one for my 120, but I think 18" is to tall. If they had a 14-16" option, maybe. I use a (kind of ugly) National Cycle Mohawk screen. Not much to look at but works pretty well. It allows some breeze but not enough to be uncomfortable.
