From Leonard Zinn’s colum on Velonews.com:
“Swiss trains are always on time, and their brakes don’t squeal when they come into the station, thanks to a special spray technicians apply to their brake pads that smoothes the friction surface with sliding platelets of molybdenum and graphite. Swisstop is sending the stuff over to the USA in large containers and having it canned in Georgia in aerosol cans so you, too, can quiet your bike’s disc brakes.”
If it really works this new spray for disc brakes made by Swiss Stop could be a big hit. I hate brake squeal and on some bikes nothing I’ve tried got rid of it [and yes I tried every trick in the book!] so I’d be happy to have a can of this in my bike tool box.
