Routing hydraulic cables through internally-routed frames can be a (big) hassle. Not only do you need to get the hoses through tiny holes in the frame, but there’s a chance for brake fluid to drip on (or into) stuff. What looks great at the end can have you looking pretty rough by the end of the install.
Lucky for you, we found a couple patents that help to ease the pain – if you are a Shimano or Campagnolo customer.
Shimano’s protective hose cap patent
First up is a very lengthy patent from Shimano. Among other things, it mentions a protective hydraulic hose cap (above). Not only does this serve to plug the end of the hose to prevent fluid leakage, it also has a hole in the end through which you can insert a cable or other guiding mechanism.
Of course, there are other ways to skin a cat if you have a system other than Shimano on your bike – it just may not result in quite the same leak-proof protection.
