i couldn’t get a close enough camera shot; but I didn’t know how meticulous the cabling process requires; now i know when i get brake adjustments at whatever bike shops i’ve been to, the adjustment is solid for on avg two days..they are not putting in the precision you are. I have to learn to do it myself. thnx..
If you aren't grinding the ends of the housing flat & perpendicular, then you aren't doing it right. It's an entire additional step, but worth it. Cutting housing, especially wound brake housing ends up with an angled end. And worse: oftentimes the wire will fold over on itself, so you have to really pay attention to removing that AND grinding. When the ends aren't flat & perpendicular, that's when you get flex in the system, leading to squishy braking and questionable index shifting.
You should do a review of those shimano cable cutters.there is no YouTube review of those
Put the camera closer so we can see what you're doing
Why plastic ferrule caps? It is the easiest I can find to buy on Amazon, but my Google searches say to buy metal, as they have less squish and are stiffer so the tension you set on the derailleur stays steady.
Wanker.
No offense, but as opposed to wasting a bit of my time there at the end of the video (it was actually even longer since I found myself having to replay that last part a couple times to figure out what the hell I was watching seeings how the informative portion just ended abruptly) You could have taken a moment to go over using that crimping tool for those of us who haven't used one before, which I'm going to go out on a limb in assuming that refers to the majority of us watching this video to begin with yeah? I'm not trying to be a cynic, it's just that was the whole reason I'd clicked this vid to begin with & you failed to even cover it...
I used this method for pushing the end-cap (Jagwire) on the housing (Jagwire) and... there are still 5mm of gap inside. Really, make a test and see for yourself. Your method is VERY VERY WRONG.
A premium ferrule/cable/housing assembly, as mentioned by Simon (below) goes like this: Insert Cable into housing pulling out sufficient excess to work with. Place hard plastic seal ring seating sleeve onto cable. It fits around the cable and into the ferrule. So it is a very small part. Next, work the rubber dust & water seal ring (even smaller) onto cable. Insert prepared cable into ferrule. The compression of the rubber ring by the pressure of the housing keeps everything nice and dry.
OK but not remotely close to a guide to ferrule fitting, eg. did you know that there are ferrules that have in-built washers to exclude water & dust?
