This combined with my excessive gear changes means that I need to replace the rear gear cable about every 3,000 km. Normally I wait until it becomes\u00a0painful\u00a0to change gears for the small bits of frayed wire sticking into my hand. But this time I decided on immediate action. Some time ago I purchased a pack of rear gear cables as I knew I was going to need to constantly replace them. But this simple task turned out to be quite a fraught one over two days. Here is the sequence of events.<\/p>\n<ul>\n<li>Sunday evening. Remove the old cable. This turned out to be very hard. Normally it just comes out. But this one I had to use the pliers to get enough force. I was worried that the outer sheath had started to rust. Even though there was no proof on the removed cable.<\/li>\n<li>I cannot thread the new cable into the outer. Even using the pliers it will only go in 10 cm and I put some kinks in the cable.<\/li>\n<li>I ride to work with a 9 speed trike. Not impossible. But well short of my normal 81 speeds.<\/li>\n<li>Monday Lunch I purchase a new outer\u00a0sheath\u00a0from <a href=\"http:\/\/woolyswheels.com\/\" target=\"_blank\" rel=\"noopener noreferrer\">wooly&#8217;s wheels<\/a> and some cable ties from Miter 10. The latter did not have the size I wanted so I\u00a0purchased\u00a0the smaller size.<\/li>\n<li>Going home I got up the 30% gradient of the car park in 5th rather than 1st gear but I needed a run-up.<\/li>\n<li>At home I remove the old outer sheath. This turns out to be very easy.<\/li>\n<li>I put in the new sheath, which also turns out to be easy. It is about 10 cm too long. But it turns out I do not have anything strong enough to cut it.<\/li>\n<li>The cable ties are way too short to be of use. But I am able to thread the cable sheath though the old cable ties.<\/li>\n<li>I put in the new \u00a0cable anyway. But it does not come out of the end of the sheath.<\/li>\n<li>It also turns out that I have the wrong ends on my cables. There are two arrangements and I have the wrong one with the barrel normal to the cable where as the trike needs one with the barrel parallel to the cable.<\/li>\n<li>I am about to give up when I notice a bit of inner cable sticking out of the old outer sheath.<\/li>\n<li>It turns out that when I removed the inner sheath, I had left behind one strand. The stand\u00a0coming\u00a0off was what made the inner hard to remove and prevented the new cable from going in.<\/li>\n<li>Using some pliers I\u00a0extracted\u00a0the single strand of wire.<\/li>\n<li>A quick test shows that the new cable fitted easily into the outer.<\/li>\n<li>I went upstairs and got a new cable to replace my kinked cable.<\/li>\n<li>I put the old sheath back on the trike.<\/li>\n<li>I put the new cable, even with the wrong barrel, on the trike.<\/li>\n<li>I trued up the rear derailleur. Here I found that it was easier to do this with the trike on it&#8217;s side.<\/li>\n<li>The gears are working again. (Fingers crossed. They did on a short test ride.)<\/li>\n<li>I need to get gear cables with the correct barrel end.<\/li>\n<\/ul>\n","protected":false},"excerpt":{"rendered":"<p>Well one of the flaws on the trike, is that it does tend to fray cables for the rear derailleur\u00a0at[&#8230;]<\/p>\n","protected":false},"author":2,"featured_media":0,"comment_status":"open","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[11],"tags":[1499,2912,3285,3488],"class_list":["post-10018","post","type-post","status-publish","format-standard","hentry","category-gt3","tag-gear-cable","tag-problems","tag-sheath","tag-strand"],"_links":{"self":[{"href":"https:\/\/yewenyi.net\/wp\/old\/index.php?rest_route=\/wp\/v2\/posts\/10018"}],"collection":[{"href":"https:\/\/yewenyi.net\/wp\/old\/index.php?rest_route=\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/yewenyi.net\/wp\/old\/index.php?rest_route=\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/yewenyi.net\/wp\/old\/index.php?rest_route=\/wp\/v2\/users\/2"}],"replies":[{"embeddable":true,"href":"https:\/\/yewenyi.net\/wp\/old\/index.php?rest_route=%2Fwp%2Fv2%2Fcomments&post=10018"}],"version-history":[{"count":0,"href":"https:\/\/yewenyi.net\/wp\/old\/index.php?rest_route=\/wp\/v2\/posts\/10018\/revisions"}],"wp:attachment":[{"href":"https:\/\/yewenyi.net\/wp\/old\/index.php?rest_route=%2Fwp%2Fv2%2Fmedia&parent=10018"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/yewenyi.net\/wp\/old\/index.php?rest_route=%2Fwp%2Fv2%2Fcategories&post=10018"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/yewenyi.net\/wp\/old\/index.php?rest_route=%2Fwp%2Fv2%2Ftags&post=10018"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
