Bike mechanic told me: Gear cable too "springy"

Bike cable housing come in two varieties, one of them is used for brakes and has an internal wound metal structure, usually, with an inner liner to reduce friction. If you'd strip the housing from its ...

What's the strongest way to bond a cable stop to an steel frame?

Don't use cable stops. The biggest load those stops will ever see is when you grab your brakes hard for an emergency stop. So you're likely to find out that whatever you did to bond the stops to the ...

What's the strongest way to bond a cable stop to an steel frame?

Beside a professionally done welding, clamp-on cable stops should be a reasonably reliable solution.

What is the proper way to cut brake cable housing?

There is a proper tool that is probably the best solution. They cut so that it does not smash the ends or the metal inside of the housing. Many also have an awl in order to help reform the end if any ...

What is bad with using the wrong cable housing?

spiraled brake housing would compress when shifting which would diminish the accuracy and using lengthwise cables for brakes can't handle the stress and split wherever the tension is too great. this ...

What tools do I absolutely need to replace brake cables?

What tools do I absolutely need to replace brake cables?

There is nothing special about Park Tool's side cutter pliers. I would guess that they re-brand reasonable quality generic ones rather than make their own. Any decent quality, sufficiently heavy duty ...

Why does the rear brake bowden have no housing below the frame of the bike?

You do not really need the housing functionally, the bowden runs straight between two fixed points. There is nothing that could compress or deform. It just works well as is. You only could add it as a ...

Why does the rear brake bowden have no housing below the frame of the bike?

Racier bikes do it above all because it's weight that can be taken away. That may sound trifling, but you get to a light bike by marginal gains in lots of little places. On other bikes it's about the ...

What are these cable "unions" called

Not sure if there is a tradition term for these. At the time of writing I found Some products simply called cable splitters or separators and Ritchey quick disconnectors

What is the quantifiable benefit of compressionless brake housing?

It's about distance, not force. Coil housing is not at all impaired in its ability to transmit force once any distance between its coils has been taken up (so no to your second question.) On any rim ...

How to pick the brake cable housing size?

5mm is the standard for bike parts made since I don't even know when, 1940s-ish. 6mm was an early MTB thing and is found on some 80s brake parts and frame housing stops. Don't worry about it unless ...

Housing cable keeps moving and gets tighter on the derailleur after jumping

It's happening because some area where the housing contacts a frame member or housing port is pulling on the housing when the suspension actuates, but not releasing it on the return. There is no ...

Question/ PSA about wavy shifter cable

Normal-ish, yes. It's normal enough that when one sees that kind of kink or distortion on a housing, it's assumable that the wires are likely to be pulling through somewhere. Yes, reasonable and then ...

Cutting brake cable housing - should initial cuts be cleaner than this?

No that's about normal. The inner liner is mushed over to one side, this always needs fixing with a pointed probe. The outer spiral winding looks rough, but remember you're cutting some springy steel ...

What should I do when my rear derailleur cable guide is too narrow?

You need a stepped shift ferrule. You have no reasonable options if you're using compressionless shift housing. On the left is a picture of a 5mm to 4mm one, which Jagwire is the main remaining ...

What is the proper way to cut brake cable housing?

While the Park Tool is the ideal tool, it is sort of a one trick pony. Meaning using it for anything other than cable housing and inners will likely damage it. I use a Dremel (brand name for an ...

It looks like you have 4mm housing put into ferrules designed for 5mm housing. The black plastic ones should be the right ones.

Why does my vintage Shimano rear derailleur come with brake style cable housing?

I assume that you have a friction shifter? A friction shifter is one that does not click into an indexed position. You just adjust it until the derailleur is lined up where you want it. Assuming this ...

How to run full length cable housing to front mech on a frame without cable stops?
