Installing cable donuts

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

They'll all pretty much end up clustered at one end anyway and thus only useful for those with OCD.

Better to get a piece of clear tubing with an ID of about 1-1.5mm and about an inch shorter than the gap between the two housing stops. That will actually protect you paint and stay there. Best is for builders to put the housing stops under the top tube...

That was my experience.

No, the best thing is for frame builders to copy what Calfee did on my Luna: Instead of a cable *stop*, it has cable *holders* on the tube tube, through which the housing passes. i.e. the housing is one continuous piece from the brifter to the rear brake. I had never seen this before, and was skeptical that it might result in a mushy lever, but that fear was unfounded.

Really? Like this?

I didn't think anybody, except vintage style steel builders, did that any more because it adds weight, can reduce breaking performance, and is completely unnecessary.

So that makes the frame stronger or weaker? How?

Get a small ID o-ring. Slice one side, install, super glue closed. You can even glue to a dry cable so it won't slide around.

I removed all the donuts, cleaned the cable with water and alcohol, and then I molded blobs of ShoeGoo onto the cables. So far, they haven't moved since they are bonded in place. They're not as quiet or discrete though.

You haven't worked on a lot of older bikes, have you?
