Best Internal Cable Routing Tutorial

Road Cycling “It is by riding a bicycle that you learn the contours of a country best, since you have to sweat up the hills and coast down them. Thus you remember them as they actually are, while in a motor car only a high hill impresses you, and you have no such accurate remembrance of country you have driven through as you gain by riding a bicycle.” -- Ernest Hemingway

Best Internal Cable Routing Tutorial

i recently purchased a new 2012 Ridley Noah RS frame on the cheap and I am trying to build it up myself. I did some searching and couldn't find any clear videos or written tutorials on how to install internal cable routing. Could someone point me to such a tutorial? specifically for the Noah RS.

Building up a hidden cable bike is little different than installing cables on an external cable bike...only difference is routing the cables through the frame.
So here are the three most popular methods of routing cables:
1. Most new framesets sold with hidden cables come with what look like long straws that are conduit for pushing the cable through the frame. A new hidden cable frameset will come with these straws installed and held in place with tape.
2. Use an old inner cable. Cables have spine to them and can be used to fish fresh cables through. Start in the entry port at the top of the downtube and push an old cable through to where it exists the BB. With a piece of tape...tie the fresh cable to the old cable and pull the fresh cable through the frame.
3. This method takes a simple small vacuum hose. Take a piece of string and start at the top of the downtube and push the string into the top port and into the down tube. The vacuum applied at the bottom of BB will suck the string through the downtube. Attach the fresh cable to the string and pull it through the downtube.

Same approach above applies to both sides of downtube...and through the drive side chain stay...and/or through the top tube for rear brake routing.

Here's a tip. A novice will invariably drop a long straw into the downtube. This is inevitable. Don't panic...they are easily retrieved and simple to reinstall as conduit to route a fresh inner cable.

Above is about all you need to know if you have basic cable installing skills. With Specialized bikes...best cable routing is called the California cross...google it if interested...whereby front and rear deraileur inner cables when routed are physically crossed inside the downtube.
Poor shifting is almost always associated with a poor set up.
Hope that helps.

Another method is just to drop the cable down to the bottom from the top hole, shine a bright flashlight in the lower frame hole at the BB to see the cable. Reach in with the j-bend of a spoke, hook it, and pull it through. For some reason, the string/vacuum doesn't work on my Fuji.
