Shimano Full Hydraulic Brake Kit

It actually stops now!

The stock drumb brake on the stacyc 12e is atrocious. My 3 year was struggling with the high lever pull force and limited braking, especially on downhills. Installing this disk brake kit is a game changer, lever pull is very light and nicely adjustable to suit small hands. Install is a bit if a pain in the butt due to the stayc rear and design but certainly doable in a couple hours. I did not have to bleed the new brake, but that might be necessary which requires some specialty tools. If you're taking your little one on anything more than a cruise around the neighborhood this is a worthy investment.
