These are a huge upgrade from drum brakes which are useless to a 2 year old with how hard they are to pull. Install on these was kind of a pain. The YouTube directions from h & s are kind of hard to follow, you can’t run the line through the frame unless you open up the line and have a special mountain bike brake bleeding kit to bleed after, and to boot the line is about a foot longer than it should be for the 12” Stacyc so you have to zip tie a coil of it out of the way. Not sure if you need special tools to resize the line.
