Review on ZYAMY Bicycle Hydraulic Housing Clamps by David Dugas

These holders are only suitable for brake hoses. You can't hold the shift cable. Some bikes have exposed cable wires in places like the top tube. Usually the mechanical brake and shifter cable wires are bare so you want to upgrade to hydraulic brakes and they have hoses. Why not have a brake hose and sleeved shifter cable (no exposed cable), well this type of holder won't hold a smaller diameter shifter cable so you'll want to wrap tape around the shifter cable? No, it's Mickey Mouse. These guys who make this holder have to make two sizes, one for the brake and one for the shift. Also, most open wire bikes only have two brackets, one on each end. The hydraulic brake line on the top tube side must have at least three holders. So buy a stick for the brakes and shift cable holder, wash the paint with alcohol. If they come loose, peel the tape off the mount and frame, then use clear silicone glue and stick the mount to dry overnight.
